Secrets of Grand Central Terminal








Grand Central Terminal, built in 1913 and the largest train station in the world, has a rich history and plenty of secrets. Explore the shady past, the hidden corners, and the many quirks of this New York City landmark.




The Whispering Gallery
The "whispering gallery" is located on the dining concourse near the famous Oyster Bar & Restaurant. Here, the acoustics of the low ceramic arches can cause a whisper to sound like a shout. Sound impossible? To test it out, you and a friend will have to stand in opposite corners of the large arched entryway. Now face the corner and whisper.
Your friend should be able to hear your voice as if you were right next to them, not whispering into a far-away corner.
According to experts, this happens because the whisperer’s voice follows the curve of the domed ceiling. The Whispering Gallery is a popular spot for marriage proposals – and a unique place to whisper sweet nothings to your main squeeze.




The Secret Passage
Underneath Grand Central Terminal, there are secret networks of underground tracks, steam-pipe tunnels, and storage areas. Hidden in these underground depths is a train platform with a secret entrance and an elevator straight up to the Waldorf-Astoria hotel.
President Franklin D. Roosevelt reportedly used this as his private entry into New York City – a way to get from his train to the hotel without being bothered by reporters. Unfortunately, you can’t currently see this secret passage for yourself. The door to the secret elevator is welded shut.




The Kissing Room
The Biltmore Room, located on the Grand Concourse across from Starbucks, was known as the “Kissing Room” during the golden age of train travel during the 1930s and 1940s. The Biltmore Room was where the famous 20th Century Limited train from the West Coast used to arrive. Passengers – including many celebrities and politicians – would get off the train and greet their loved ones here with kisses and hugs. Often, they would then go up the stairs into the famous Biltmore Hotel (now the Bank Of America building).




Oh My Stars
The ceiling over the Main Concourse, with its famous mural of the stars, is one of Grand Central Terminal’s most famous features. However, eagle-eyed visitors will notice that the zodiac on the ceiling is depicted backwards. Some have speculated that this was a mistake by the artist, Paul Helleu. The real reason, however, is that the painter was inspired by a medieval manuscript that showed the heavens as they would have been seen from outside the celestial sphere.
The famous ceiling has another, more recent, secret. If you look carefully, you will see a patch of dark on the carefully-restored blue of the mural. This patch shows the color of the ceiling before restoration. It was left as a reminder of how much work was done.

Birth order

From Wikipedia, the free encyclopedia

Will the younger sister be more pampered than the firstborn?The phrase birth order is defined as a person's rank by age among his or her siblings. Birth order is commonly believed to have a profound and lasting effect on psychological development. Although this assertion has been repeatedly challenged by researchers, birth order continues to have a strong presence in pop psychology and popular culture.


- Theories
Alfred Adler (1870-1937), an Austrian psychiatrist, and a contemporary of Sigmund Freud and Carl Jung, was one of the first theorists to suggest that birth order influences personality. He argued that birth order often can leave an indelible impression on the individual's style of life, which is a habitual way of dealing with the tasks of friendship, love, and work. Other factors that may be equally influential are: parental attitudes; organ inferiority, illness, and disability; gender confusion; or social, economic and religious circumstances. Any overburdening factor may intensify normal inferiority feelings and lead to unconscious compensations or over-compensations (i.e, an extremely talented older or younger sibling). Other birth order factors that should be considered are: the spacing in years between siblings; the total number of children; and the changing circumstances of the parents over time. Adler suggested that birth order does not cause any direction of personality development, but it may be used by the individuals as a building brick for their freely chosen style of life and fictional final goal. Many researchers, in attempting to prove or disprove the sole effects of birth order, cite the complexity of other influences.
The influence of birth order on the development of personality is a controversial issue in psychology. It is widely believed that personality is strongly influenced by birth order, but many psychologists dispute this. Personality psychologists largely (though by no means without debate) agree that the Big Five personality traits (also known as Five Factor) represent something like a natural taxonomy of human personality variables. Cross-linguistically the vast majority of adjectives used to describe human personality fit into one of the following five areas, easily remembered by the acronym OCEAN: Openness, Conscientiousness, Extroversion, Agreeableness, and Neuroticism.
In his book Born to Rebel, Frank Sulloway suggests that birth order effects on the Big Five are strong and consistent. He argues that firstborns to be more conscientious, more socially dominant, less agreeable, and less open to new ideas compared to laterborns. However, critics such as Fred Townsend, Toni Falbo, and Judith Rich Harris, claim to have refuted Sulloway's theories. An issue of Politics and the Life Sciences, dated September, 2000 but not published until 2004 [1] due to legal threats from Sulloway (who claimed its content to be defamatory, although it was carefully and rigorously researched and sourced), contains criticisms of Sulloway's theories, including studies that show conflicting findings.
In their book Sibling Relationships: Their Nature and Significance across the Lifespan Michael E. Lamb, Brian Sutton-Smith, Lawrence Erlbaum Associates make the point that sibling relationships often last an entire lifetime. They point out that the lifespan view proposes that development is continuous, with individuals continually adjusting to the competing demands of socialization agents and endogenous tendencies. Thus, even those concerned only with interactions among young siblings implicitly or explicitly acknowledge that all relationships change over time and that any "effects" may be eliminated, reinforced, or altered by later experiences.

Family roles govern the perceived expectations and responsibilities placed on children by parents and siblings. Children's perception of their place in the family constellation influences how they feel about themselves and how they interact with others (Koffman & Johnson, 1993 in Nims, 1998). It is also possible that children internalize roles and traits determined by their birth order.

- Firstborn
Firstborns are typically believed to be serious, conscientious, directive, goal-oriented, aggressive, rule-conscious, exacting, conservative, organized, responsible, jealous, fearful, high achieving, competitive, high in self-esteem, and anxious. They may learn the concept of power at a young age, and this can be expressed in their desire to help, protect and lead others. The firstborn may also have the need to regain praise from their parents that they received before their siblings were born. The first born may come to feel unloved through the perceived loss of mother's love to the new baby. Adler (1964) referred to this as being "dethroned" by the younger sibling. Later in life the firstborn may become authoritarian or strict. A firstborn's common feeling of a fear of losing the top position may make them more risk averse, and thus less likely to embark on a new venture.
There are several aspects of the family structure that pertain to firstborn children. First time parents are usually highly anxious and "sweat all the details." They document every milestone, celebrate each small achievement, and worry if it comes later than expected. They put the firstborn child under a lot of pressure to succeed. In addition to parental behavior, the firstborn child is often shocked by the introduction of a competitor into the family. This may lead to sibling rivalry. On the other hand, younger siblings often idolize the first born, putting the first born in a position of leader of the children of the family.

- Middleborn
Middleborn children have a diverse range of personalities. The habits of many middleborns are motivated by the fact that they have never been truly in the spotlight. The firstborn always seems to be achieving and pioneering ahead, while the younger sibling is secure in his or her niche as the entertainer of the family.
The middle or second born child or children often have the sense of not belonging. They fight to receive attention from parents and others because they feel many times they are being ignored or dubbed off as being the same as another sibling. Being in the middle, a child can feel insecure. This in turn will affect their relationships throughout their whole life. In some cases the middle child will see life from a hopeless standpoint will often become depressed or even lonely.The middle child often lacks drive and looks for direction from the first born child. Sometimes a middle child feels out of place because they are not over achievers and like to go with the flow of things.
Middleborn children are often believed to be natural mediators. They tend to have fewer pictures in the family photo album alone, compared to firstborns. Middleborn children may avoid conflict. They may also be highly loyal to the peer group and have many friends.
The middle born child may develop good social skills and have an easier time growing up with an other-centered point of view. It has been suggested that middleborn children are more likely to be entrepreneurs. Karen E. Klein, a Los Angeles-based writer, suggested that a middleborn's innate skills in diplomacy plus their flexibility in ideas make them more successful in entrepreneurship.
The middle child may have an even-temper and a take it or leave it attitude. Alfred Adler (1964) believed that the middle child feels squeezed out of a position of privilege and significance. The child is internally compelled to find peace within the family and may have trouble finding a place or become a fighter of injustice.

- Youngest
The names given to the youngest child are revealing: the youngest child of the family is viewed as the party animal, the enterainer who is unafraid to test his or her luck. They are also thought of as the baby of the family and an outgoing charmer. While this is certainly not true of all youngest siblings, proponents of this theory state that the youngest of the family is an endearing, and delightful friend.
The youngest child is often babied or "pampered" more than the other siblings. This "pampering," according to Adler, is one of the worst behaviors a parent can bestow on a child. "Pampering" can lead to dependence, and selfishness as well as irresponsibility when the youngest enters adulthood.
Youngest children may become manipulative and control-seeking if their sibling(s), parents, or other peers are overbearing or bossy.

- Only children
Main article: Only child
Only children may have characteristics of either the first born or the youngest child. Adler (1964) believed that because only children have no rivals for their parents' affection, they may be pampered and spoiled by their parents, particularly the mother. He suggested that this could cause later interpersonal difficulties if the person is not universally liked and admired.
Another view of only children, as noted by Alissa Eischens in her paper The Dilemma of the Only Child is that they learn to be children on their own, they learn to depend on themselves, and they have no problem being loners.
Naturally introverted only children may show extroverted qualities if he or she wishes to make friends. On the other hand, naturally extroverted children may learn to show introverted qualities by being content to focus on their thoughts when playmates are unavailable.

- Twins
twins tend to have one dominate twin, who acts as the first born. however this can sometimes not be the case. because of twins closeness, they tend to be alot more confident, however they often have trouble being alone, and get lonely easily. when one twin gets married this often causes seperation problems with both twins, and sometimes leads to depression. twins, especially identical twins, tend to be much closer than normal siblings.

- Personality research
Most of the claims about birth order have not been supported by scientific research. Indeed, many of the traits believed to be associated with different birth positions appear to contradict each other. Only children are supposedly more extraverted because they need to go outside of the family to meet other children, yet they are also believed to be more introverted so they can tolerate being by themselves. In fact, Extraversion and Introversion are stable personality traits, and they are related more strongly to genetic factors than to birth order. Firstborns are attributed with a variety of traits that do not even correlate with each other, much less with birth order. In general, birth order effects are weaker than commonly believed.
In practice, systematic birth order research is a challenge because it is difficult to control for all of the variables that are statistically related to birth order. Family size, and a number of social and demographic variables are associated with birth order and serve as potential confounds. For example, large families are generally lower in socioeconomic status than small families. This means that third born children are not only third in birth order, but they are also more likely to come from larger, poorer families than firstborn children. If thirdborns have a particular trait, it may be due to birth order, or it may be due family size, or to any number of other variables. It is often impossible to determine which variable is the actual cause of the observed trait. This methodological issue has plagued research in this area. Spacing of children, parenting style, and gender are additional variables to consider. Consequently, there is a large number of published studies on birth order that vary widely in quality and are inconsistent in their conclusions.
Literature reviews that have examined many studies and attempted to control for confounding variables tend to find minimal effects for birth order. Ernst and Angst (1983) reviewed all of the research published between 1946 and 1980. They also did their own study on a representative sample of 6,315 young men from Switzerland. They found no substantial effects of birth order and concluded that birth order research was a "waste of time." More recently, Jefferson, Herbst, and McCrae (1998) analyzed data from a national sample of 9,664 subjects on the Big five personality traits of extraversion, neuroticism, agreeableness, conscientiousness, and openness to experience. Contrary to Sulloway's predictions, they found no significant correlation between birth order and self-reported personality. There was, however, some tendency for people to perceive birth order effects when they were aware of the birth order of an individual.
In her review of the scientific literature, Judith Rich Harris (1998) suggests that birth order effects may exist within the context of the family of origin, but that they are not enduring aspects of personality. When people are with their parents and siblings, firstborns behave differently than laterborns, even during adulthood. However, most people don't spend their adult lives in their childhood home. Harris provides evidence that the patterns of behavior acquired in the childhood home don't affect the way people behave outside the home, even during childhood. Harris concludes that birth order effects keep turning up because people keep looking for them, and keep analyzing and reanalyzing their data until they find them.

- Intelligence
Summary of the findings of Belmont and Marolla. Scores on Raven's Progressive Matrices relate to birth order and family size.Since the 1970s, one of the most influential theories to explain why firstborns frequently score higher on intelligence and achievement tests than other children is the confluence model of Robert Zajonc. This model states that because firstborns mainly have adult influences around them in their early years, they will spend their initial years of life interacting in a highly intellectual family environment. This effect may also be observed in siblings who, although later born, have a sibling at least five years senior with no siblings in between. These children are considered to be "functional firstborns". The theory further suggests that firstborns will be more intelligent than only children, because the latter will not benefit from the "tutor effect" (i.e. teaching younger siblings).
Zajonc's theory has been criticised for confounding birth order with both age and family size, and alternative theories (such as Resource Depletion Theory) have been offered to explain the Belmont and Marolla findings. In a meta-analysis of the research, Polit and Falbo (1988) found that firstborns, only children, and children with one other sibling score higher on tests of verbal ability than laterborns and children with multiple siblings. This effect suggests that smaller families lead to children with higher test scores. Because there was no specific advantage for firstborn children, the results are consistent with Resource Depletion Theory, but not the confluence model.
The basic finding that firstborns have higher IQ scores has been disputed. One group of researchers examined data from the National Longitudinal Survey of Youth (NLSY) (USA), which gave them the opportunity to look at a large randomly selected sample of US families. The sample included children whose academic performance had been reviewed multiple times throughout their academic careers. This study found no relationship between birth order and intelligence (Rodgers, Cleveland, Van den Oord, & Rowe, 2000).
Researchers reporting in the journal Science in June 2007 found that "The eldest children in families tend to develop slightly higher IQs than their younger siblings." [1]

Big Five personality traits

From Wikipedia, the free encyclopedia


In psychology, the Big Five personality traits are five broad factors or dimensions of personality discovered through empirical research (Goldberg, 1993). These factors are Neuroticism, Extraversion, Agreeableness, Conscientiousness, and Openness to Experience. Each factor consists of a number of more specific traits. For example, extraversion includes such related qualities as sociability, excitement seeking, and positive emotions.
The Big Five are a descriptive model of personality, and psychologists have developed theories to account for the Big Five.


Overview
The Big Five factors and their constituent traits can be summarized as follows. For additional details, go to this section below.


  1. Openness to Experience - appreciation for art, emotion, adventure, unusual ideas, imagination, and curiosity.

  2. Conscientiousness - a tendency to show self-discipline, act dutifully, and aim for achievement; planned rather than spontaneous behaviour.

  3. Extraversion - energy, positive emotions, surgency, and the tendency to seek stimulation and the company of others.

  4. Agreeableness - a tendency to be compassionate and cooperative rather than suspicious and antagonistic towards others.

  5. Neuroticism - a tendency to experience unpleasant emotions easily, such as anger, anxiety, depression, or vulnerability; sometimes called emotional instability.


Some scholarly works refer to the Big Five as the Five-Factor Model. These factors are also referred to as the OCEAN or CANOE models of personality. When scored for individual feedback, they are frequently presented as percentile scores, with the median at 50%. For example, a Conscientiousness rating in the 80th percentile indicates a relatively strong sense of responsibility and orderliness, whereas an Extraversion rating in the 5th percentile indicates an exceptional need for solitude and quiet.
It is important to note that these trait clusters are statistical aggregates. Exceptions may exist on individual personality profiles. On average, people high in Openness are intellectually curious, open to emotion, interested in art, and willing to try new things. A particular individual, however, may have a high overall Openness score and be interested in learning and exploring new cultures. Yet he might have no great interest in art or poetry. Situational influences also exist, as even extraverts may occasionally need time away from people.

History
- Early trait research
Sir Francis Galton was the first scientist to recognize what is now known as the Lexical Hypothesis. This is the idea that the most salient and socially relevant personality differences in people’s lives will eventually become encoded into their language. The hypothesis further suggests that by sampling language, it is possible to derive a comprehensive taxonomy of human personality traits.
In 1936, Gordon Allport and H. S. Odbert expanded on the hypothesis. They worked through two of the most comprehensive dictionaries of the English language available at the time and extracted 18,000 personality-describing words. They then reduced this gigantic list to 4500 adjectives which they considered to describe observable and relatively permanent traits.
Raymond Cattell (1957) obtained the Allport-Odbert list and eliminated synonyms to reduce the total to 171. He then asked subjects to rate people whom they knew by the adjectives on the list and analyzed their ratings. Cattell identified 35 major clusters of personality traits, and then added ten more traits obtained from a review of the psychiatric literature. Cattell and his associates constructed personality tests for these 45 traits, and the data they obtained from these tests was analyzed with the emerging technology of computers combined with the statistical method of factor analysis. This resulted in sixteen major personality factors, which led to the development of the 16PF Personality Questionnaire.
In 1961, two Air Force researchers, Tupes and Christal analyzed personality data from eight large samples. Using Cattell's trait measures, they found five recurring factors. This work was replicated by Norman (1963), who also found that five major factors were sufficient to account for a large set of personality data. Norman named these factors Surgency, Agreeableness, Conscientiousness, Emotional Stability, and Culture.

- Hiatus in research
For the next two decades, the changing zeitgeist made publication of personality research difficult. In his 1968 book Psychological Assessment, Walter Mischel asserted that personality tests could not predict behavior with a correlation of more than 0.3. Social psychologists like Mischell argued that attitudes and behavior were not stable, but varied with context. Predicting behavior by personality tests was considered to be impossible. Radical situationists in the 1970s went so far as to argue that personality is merely a perceived construct that people impose on others in order to maintain an illusion of consistency in the world.
Emerging methodologies challenged this point of view during the 1980s. Instead of trying to predict single instances of behavior, which was unreliable, researchers found that they could predict patterns of behavior by aggregating large numbers of observations. As a result correlations between personality and behavior increased substantially, and it was clear that "personality" did in fact exist. Personality and social psychologists now generally agree that both personal and situational variables are needed to account for human behavior. Trait theories became justified, and there was a resurgence of interest in this area.
By 1980, the pioneering research by Tupes, Christal, and Norman had been largely forgotten by psychologists. Goldberg (1981) started his own lexical project with a new set of adjectives from the dictionary and independently found the five factors once again.

- Consensus on the Big Five
In a 1981 symposium in Honolulu, four prominent researchers, Lewis Goldberg, Naomi Takemoto-Chock, Andrew Comrey, and John M. Digman, reviewed the available personality tests of the day. They concluded that the tests which held the most promise measured a subset of five common factors, just as Norman had discovered in 1963. This event was followed by widespread acceptance of the five factor model among personality researchers during the 1980s, as well as the publication of the NEO PI-R five-factor personality inventory by Costa and McCrae in 1985.
One of the most significant advances of the five-factor model was the establishment of a common taxonomy that demonstrates order in a previously scattered and disorganized field. What separates the five-factor model of personality from all others is that it is not based on the theory of any one particular psychologist, but rather on language, the natural system that people use to understand one another.
A number of meta-analyses have confirmed the predictive value of the Big Five across a wide range of behaviors. Saulsman and Page (2004) examined the relationships between the Big Five personality dimensions and each of the 10 personality disorder categories in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Across 15 independent samples, the researchers found that each disorder displayed a unique and predictable five-factor profile. The most prominent and consistent personality predictors underlying the disorders were positive associations with Neuroticism and negative associations with Agreeableness.
In the area of job performance, Barrick and Mount (1991, 1998) reviewed 117 studies utilizing 162 samples with 23,994 participants. They found that conscientiousness showed consistent relations with all performance criteria for all occupational groups. Extraversion was a valid predictor for occupations involving social interaction (e.g. management and sales). Furthermore, extraversion and openness to experience were valid predictors of training proficiency criteria.

Extraversion
Extraversion (also "extroversion") is marked by pronounced engagement with the external world. Extraverts enjoy being with people, are full of energy, and often experience positive emotions. They tend to be enthusiastic, action-oriented individuals who are likely to say "Yes!" or "Let's go!" to opportunities for excitement. In groups they like to talk, assert themselves, and draw attention to themselves.
Introverts lack the exuberance, energy, and activity levels of extraverts. They tend to be quiet, low-key, deliberate, and less dependent on the social world. Their lack of social involvement should not be interpreted as shyness or depression; the introvert simply needs less stimulation than an extravert and more time alone to re-charge their batteries.

- Sample Extraversion items
I am the life of the party.
I don't mind being the center of attention.
I feel comfortable around people.
I start conversations.
I talk to a lot of different people at parties.
I am quiet around strangers. (reversed)
I don't like to draw attention to myself. (reversed)
I don't talk a lot. (reversed)
I have little to say. (reversed)
I keep in the background. (reversed) [1]


- Biology of Extraversion
Extraversion has been linked to higher sensitivity of the mesolimbic dopamine system to potentially rewarding stimuli (Depue & Collins, 1999). This in part explains the high levels of positive affect found in Extraverts, since they will more intensely feel the excitement of a potential reward. One consequence of this is that Extraverts can more easily learn the contingencies for positive reinforcement, since the reward itself is experienced as greater.

- Agreeableness
Agreeableness reflects individual differences in concern with cooperation and social harmony. Agreeable individuals value getting along with others. They are therefore considerate, friendly, generous, helpful, and willing to compromise their interests with others’. Agreeable people also have an optimistic view of human nature. They believe people are basically honest, decent, and trustworthy.
Disagreeable individuals place self-interest above getting along with others. They are generally unconcerned with others’ well-being, and therefore are unlikely to extend themselves for other people. Sometimes their skepticism about others’ motives causes them to be suspicious, unfriendly, and uncooperative.
Agreeableness is obviously advantageous for attaining and maintaining popularity. Agreeable people are better liked than disagreeable people. On the other hand, agreeableness is not useful in situations that require tough or absolute objective decisions. Disagreeable people can make excellent scientists, critics, or soldiers.
There is some criticism on the use of the terms altruism-egoism in this context. Evolutionary Biology has extensively researched the mechanisms of altruism and concluded that agreeableness differs fundamentally from altruism.

- Sample Agreeableness items
I am interested in people.
I feel others’ emotions.
I have a soft heart.
I make people feel at ease.
I sympathize with others’ feelings.
I take time out for others.
I am not interested in other people’s problems. (reversed)
I am not really interested in others. (reversed)
I feel little concern for others. (reversed)
I insult people. (reversed) [2]


- Conscientiousness
Conscientiousness concerns the way in which we control, regulate, and direct our impulses. Impulses are not inherently bad; occasionally time constraints require a snap decision, and acting on our first impulse can be an effective response. Also, in times of play rather than work, acting spontaneously and impulsively can be fun. Impulsive individuals can be seen by others as colorful, fun-to-be-with, and zany. Conscientiousness includes the factor known as Need for Achievement (NAch).
The benefits of high conscientiousness are obvious. Conscientious individuals avoid trouble and achieve high levels of success through purposeful planning and persistence. They are also positively regarded by others as intelligent and reliable. On the negative side, they can be compulsive perfectionists and workaholics. Furthermore, extremely conscientious individuals might be regarded as stuffy and boring. Unconscientious people may be criticized for their unreliability, lack of ambition, and failure to stay within the lines, but they will experience many short-lived pleasures and they will never be called stuffy (i.e. dull, boring, unimaginative).

- Sample Conscientiousness items
I am always prepared.
I am exacting in my work.
I follow a schedule.
I get chores done right away.
I like order.
I pay attention to details.
I leave my belongings around. (reversed)
I make a mess of things. (reversed)
I often forget to put things back in their proper place. (reversed)
I shirk my duties. (reversed) [3]


- Neuroticism
Neuroticism, also known inversely as Emotional Stability, refers to the tendency to experience negative emotions. Those who score high on Neuroticism may experience primarily one specific negative feeling such as anxiety, anger, or depression, but are likely to experience several of these emotions. People high in Neuroticism are emotionally reactive. They respond emotionally to events that would not affect most people, and their reactions tend to be more intense than normal. They are more likely to interpret ordinary situations as threatening, and minor frustrations as hopelessly difficult. Their negative emotional reactions tend to persist for unusually long periods of time, which means they are often in a bad mood. These problems in emotional regulation can diminish a neurotic's ability to think clearly, make decisions, and cope effectively with stress.
At the other end of the scale, individuals who score low in Neuroticism are less easily upset and are less emotionally reactive. They tend to be calm, emotionally stable, and free from persistent negative feelings. Freedom from negative feelings does not mean that low scorers experience a lot of positive feelings; frequency of positive emotions is a component of the Extraversion domain.

- Sample Neuroticism items
I am easily disturbed.
I change my mood a lot.
I get irritated easily.
I get stressed out easily.
I get upset easily.
I have frequent mood swings.
I often feel blue.
I worry about things.
I am relaxed most of the time. (reversed)
I seldom feel blue. (reversed) [4]


- Openness to Experience
Openness to Experience describes a dimension of personality that distinguishes imaginative, creative people from down-to-earth, conventional people. Open people are intellectually curious, appreciative of art, and sensitive to beauty. They tend to be, compared to closed people, more aware of their feelings. They therefore tend to hold unconventional and individualistic beliefs, although their actions may be conforming (see agreeableness). People with low scores on openness to experience tend to have narrow, common interests. They prefer the plain, straightforward, and obvious over the complex, ambiguous, and subtle. They may regard the arts and sciences with suspicion, regarding these endeavors as abstruse or of no practical use. Closed people prefer familiarity over novelty; they are conservative and resistant to change.

- Sample Openness items
I am full of ideas.
I am quick to understand things.
I have a rich vocabulary.
I have a vivid imagination.
I have excellent ideas.
I spend time reflecting on things.
I use difficult words.
I am not interested in abstract ideas. (reversed)
I do not have a good imagination. (reversed)
I have difficulty understanding abstract ideas. (reversed) [5]
- Causes of Openness
Openness is heritable, like all of the major personality dimensions, with estimates clustering around 0.4. One environmental cause of increased openness appears to be exposure to tertiary (College US / University Brit.) education.

- Correlates of Openness
Openness is correlated weakly (≤.3) with measures of creativity, and with intelligence test scores. Current analyses suggest that the correlation with IQ is due to a subset of Openness measures acting as self-report IQ measures. It is possible that openness is a mechanism facilitating access to novel thoughts — this would explain the correlation of openness (O) to responses on creativity measures such as imagining different uses for common objects.
Openness is often presented as healthier or more mature by psychologists. However, open and closed styles of thinking are useful in different environments. The intellectual style of the open person may serve a professor well, but research has shown that closed thinking is related to superior job performance in police work, sales, and a number of service occupations.

- Biology of Openness
Higher levels of Openness have been linked to activity in the ascending dopaminergic system and the functions of the dorsolateral prefrontal cortex. Openness is the only personality trait that correlates with neuropsychological tests of dorsolateral prefrontal cortical function, supporting the link between Openness and IQ (DeYoung, Peterson, & Higgins, 2005)

- Selected scientific findings
Ever since the 1990s when the consensus of psychologists gradually came to support the Big Five, there has been a growing body of research surrounding these personality traits (see for instance, Robert Hogan's edited book "Handbook of Personality Psychology" (Academic Press, 1997).

- Heritability studies
All five factors show an influence from both heredity and environment. Twin studies suggest that these effects contribute in roughly equal proportion (Jang, Livesley & Vernon, 1996).

- Change and development
During young adulthood, a person's ratings on the five factors may change, with average levels of Agreeableness and Conscientiousness typically increasing, and with Extraversion, Neuroticism, and Openness generally decreasing. However, after age 30, researchers have found that stability, not change is the general rule. Both longitudinal data, which correlate people's test scores over time, and cross-sectional data, which compare personality levels across different age groups, show remarkable stability in adulthood (McCrae & Costa, 1990). This is not to say that personality as measured on the Big Five cannot change, given life altering circumstances or efforts to do so. It does indicate, however, that after age 30, people generally do not change their personalities very much.

- Gender differences
Men and women show differences in Big Five scores across cultures, with women scoring higher in both the Agreeableness and Neuroticism domains. These findings may indicate innate gender differences in personality, but are not conclusive.

- Birth order
The suggestion has often been made that individuals differ by the order of their births. Frank J. Sulloway argues that birth order is correlated with personality traits. He claims that firstborns are more conscientious, more socially dominant, less agreeable, and less open to new ideas compared to laterborns.
However, Sulloway’s case has been discredited because his data confound family size with birth order. Subsequent analyses have shown that birth order effects are only found in studies where the subjects’ personality traits are rated by family members (such as siblings or parents) or by acquaintances familiar with the subjects’ birth order. Large scale studies using random samples and self-report personality tests like the NEO PI-R have found no significant effect of birth order on personality (Harris, 2006; Jefferson, Herbst, & McCrae, 1998).

- Cultural differences
Recent work has also found relationships between Geert Hofstede’s cultural factors, Individualism, Power Distance, Masculinity, and Uncertainty Avoidance, with the average Big Five scores in a country. For instance, the degree to which a country values individualism correlates with its average Extraversion, while people living in cultures which are accepting of large inequalities in their power structures tend to score somewhat higher on Conscientiousness. The reasons for these differences are as yet unknown; this is an active area of research.

- Criticisms
Much research has been conducted into the Big Five. However relatively little of the research has been published in a collated form; most of it appears relatively uncompiled in research journals. For the best understanding of the Big Five, one must be up to date on the literature, which may tend to limit a complete understanding by laypeople.
Block (1995) gave a detailed critique of the Big Five in A contrarian view of the five-factor approach to personality description. Costa and McCrae (1995) answered this paper in Solid ground in the wetlands of personality: A reply to Block.
There are a number of frequently cited criticisms of the Big Five. Some of these are acknowledged by its proponents of the system; others have been disputed in various ways.

- Limited scope
One common criticism is that the Big Five do not explain all of human personality. Some psychologists have dissented from the model precisely because they feel it neglects other domains of personality, such as Religiosity, Manipulativeness/Machiavellianism, Honesty, Thriftiness, Conservativeness, Masculinity/Femininity, Snobbishness, Sense of humour, Identity, Self-concept, and Motivation. Correlations have been found between some of these variables and the Big Five, such as the inverse relationship between political conservatism and Openness (see McCrae, 1996), although variation in these traits is not entirely explained by the Five Factors themselves. McAdams (1995) has called the Big Five a "psychology of the stranger," because they refer to traits that are relatively easy to observe in a stranger; other aspects of personality that are more privately held or more context-dependent are excluded from the Big Five.
In many studies, the five factors are not fully orthogonal to one another; that is, the five factors are not independent. Negative correlations often appear between Neuroticism and Extraversion, for instance, indicating that those who are more prone to experiencing negative emotions tend to be less talkative and outgoing. Orthogonality is viewed as desirable by some researchers because it minimizes redundancy between the dimensions. This is particularly important when the goal of a study is to provide a comprehensive description of personality with as few variables as possible.

- Methodological issues
The methodology used to identify the dimensional structure of personality traits, factor analysis, is often challenged for not having a universally-recognized basis for choosing among solutions with different numbers of factors. That is, a five factor solution depends on some degree of interpretation by the analyst. A larger number of factors may, in fact, underlie these five factors. This has lead to disputes about the "true" number of factors. Big Five proponents have responded that although other solutions may be viable in a single dataset, only the five factor structure consistently replicates across different studies.
A methodological criticism often directed at the Big Five is that much of the evidence relies on self report questionnaires; self report bias and falsification of responses is impossible to deal with completely. This becomes especially important when considering why scores may differ between individuals or groups of people - differences in scores may represent genuine underlying personality differences, or they may simply be an artifact of the way the subjects answered the questions. The five factor structure has been replicated in peer reports (e.g., Goldberg, 1990); however, many of the substantive findings rely on self-reports.

- Theoretical status
A frequent criticism is that the Big Five is not based on any underlying theory; it is merely an empirical finding that certain descriptors cluster together under factor analysis. While this does not mean that these five factors don't exist, the underlying causes behind them are unknown. There is no theoretical justification for why sensation seeking and gregariousness are predictive of general Extraversion, for instance; this is an area for future research to investigate. Several overarching theoretical models have been proposed to cover all of the Big Five, such as Five-Factor Theory and Social Investment Theory. Temperament Theory may prove to provide a theoretical foundation for the Big Five, and provide a longitudinal (life-span) model in which the Big Five could be grounded.15:45, 6 July 2007 (UTC)12.33.120.36

- Further research
Current research concentrates on a number of areas. One important question is: are the five factors the right ones? Attempts to replicate the Big Five in other countries with local dictionaries have succeeded in some countries but not in others. Apparently, for instance, Hungarians don’t appear to have a single Agreeableness factor (Szirmak, & De Raad, 1994). Proponents state that the problem is that the language does not provide enough variance of the related terms for proper statistical analysis (CITE). Other researchers (De Fruyt, McCrae, Szirmák & Nagy, 2004) find evidence for Agreeableness but not for other factors.
In an attempt to explain variance in personality traits more fully, some have found seven factors (Cloninger, Svrakic, & Przybeck, 1993), some eighteen (Livesley & Jackson, 1986), and some only three (CITE). What determines the eventual number of factors is essentially the kind of information that is put into the factor analysis in the first place (i.e. the "Garbage in, Garbage out" principle). Since theory often implicitly precedes empirical science (such as factor analysis), the Big Five and other proposed factor structures should always be judged according to the items that went into the factor analytic algorithm. Recent studies show that seven- or eighteen-factor models have their relative strengths and weaknesses in explaining variance in DSM-based symptom counts in non-clinical samples (Bagby, Marshall, Georgiades, 2005) and in psychiatric patients (De Fruyt, De Clercq, van de Wiele, Van Heeringen, 2006) and do not seem to be clearly outperformed by the Big Five.
A second question is: Which factors predict what? Job outcomes for leaders and salespeople have already been measured, and research is currently being done in expanding the list of careers. There are also a variety of life outcomes which preliminary research indicates are affected by personality, such as smoking (predicted by high scores in Neuroticism and low scores in Agreeableness and Conscientiousness) and interest in different kinds of music (largely mediated by Openness).
A third area of investigation is to make a model of personality. The Big Five personality traits are empirical observations, not a theory; the observations of personality research remain to be explained. Costa and McCrae have built what they call the Five Factor Theory of Personality as an attempt to explain personality from the cradle to the grave. They don't follow the lexical hypothesis, though, but favor a theory-driven approach inspired by the same sources as the sources of the Big Five.
A fourth area of investigation is the downward extension of Big Five theory, or the Five Factor Model, into childhood. Studies have found Big Five personality traits to correlate with children's social and emotional adjustment and academic achievement. More recently, the Five Factor Personality Inventory - Children (Mcghee, Ehrler, & Buckhalt, 2007) was published extending assessment between the ages of 9-0 to 18-11.

How to Tips for Surfing Beginners!


Surfboards are made to float on the water. They have a natural center of gravity. If you were to lay any surfboard in a swimming pool, it would come to rest the same way every time.
What you want to do when you lay on a surf board is to have the board remain in the same relation to the water as it was without your weight on it, just a bit lower in the water.


Mark The Balance Point:

A good tip is to find this balance point is to lay on your board then make a mark right at your chin. This spot is best made with a bit of wax or a magic marker. It is a reference point that enables you to put your chin on the same spot every time, so the board will react to your weight the same way every time.

Pearling:

If the board's nose digs into the water it is called pearling and you must move the location of "your chin" back. To adjust, just slide back an inch from the mark and make a mental note.

Corking:

Too much weigh in the back and the board will cork. This is a common mistake amongst beginners. You cannot catch a wave if you are corking your board. Move up an inch at a time till the board lies in the water naturally. This will provide you with the maximum hull speed and minimum drag from the water displacement that you are causing with your weight.

Paddle With The Crawl Stroke:

Do not paddle with both arms simultaneously because this will cause the board to speed up and slow down in the water and you will not be able to maintain constant hull speed through the water. Always paddle with the crawl stroke...one arm and then the other alternatively. This will provide you with a constant speed so you can catch that wave.

Sitting On The Board:

Ok, so now we know how to lie on the board and paddle the board. Now it's time to learn how to sit on the board. The first time try this you may be quite wobbly. The key to doing this well is being calm, or trying to be still. The less movement that you make, the easier you will find it is to do this. All the other skills of surfing will improve as you learn to be "calm" while surfing.

Standing On The Board:

Now it's time to learn how to stand up. This is something you have been doing all your life. Lie on your chest, your head up, looking ahead. Put your hands on the board beside your shoulders, palms down like you were going to do a push up. Push your upper body up and at the same time sweep your feet under you. Make sure your feet are laying on the stringer, the line down the middle of the board. This move keeps your weight centered along the stringer.
When you come up, remember to keep low. If you stand erect you will fall. Assume a position of a sumo wrestler. Press your feet shoulder width apart and "grip the board in your feet", opposite of the way you would press your thighs together on a horse. Have your hands a bit higher than your waist and just in view of your vision. Always look up! If you look at your feet, you will fall down. I promise!

Practice This For Hours:

Have someone watch you and have them critique your performance. Practice jumping up without making a sound on the floor. Calm and controlled is the smoothest way to approach this...so practice doing it quietly. If you have a surfboard, lay it on a large bed or in the sand and do this exercise. This is a way for you to judge your ability to be controlled.

Safety:


  • Never have your board between yourself and the coming waves!
  • To avoid collision with others, keep a safe distance, say fifteen feet or the length of you, your leash and board combined.
  • Beginners should always wear a leash or leg rope tied to their surfboard.
  • Every beginner surfboard should also have a safety nose guard to prevent dangerous impacts with the surfboard nose.
  • Beginners should always surf with a buddy for safety, plus it is cool to share your surf experiences with someone else.
  • Never push your board through the water fin first. The fin or fins were made to keep the board pointing nose first. Pushing the board fins first can be quite dangerous because the board wants to go the other direction.
  • Beginner surfers should consider wearing a vest, rash guard or tee shirt to avoid the rubbed rash they will get on their stomach and chest.
  • When you fall off your board, cover the back of your head with your hands, with your wrists over your ears and your elbows together. Stay under water for a moment longer than necessary.
  • There are companies that make helmets and this is another alternative.
  • When you come up, try to be facing the oncoming waves and look for your board's location immediately. Loose boards, propelled by the strength of the ocean, are very dangerous objects for swimmers.


Surfing Etiquette:

The first standing surfer that is closest to the breaking wave has the right of way on that wave. Anyone paddling for that wave must quit. There are natural repercussions to not following this rule that can be very dangerous.
Most known surf spots have locals who surf that spot every day and some believe that they "own the beach". We all know that this is not the case. Having said that, the stranger, no matter their ability, should endeavor to show some respect for these social dinosaurs.
The surfer riding the wave has the right of way and the paddlers who are paddling out must yield. This means that the paddlers must paddle out of the way whenever possible, even if it is into the breaking wave or behind the rider. If you are paddling for a wave and someone is paddling out toward you, make eye contact with that person and indicate your intentional direction in reference to them. A nod in the direction you are going can work.

Conclusion:

Every situation is different so practice being nice in the water. It will make you feel good, I promise. Hooting for a good wave or encouraging someone is good too. Remember, you will get what you give.

Dieting Advice For Men

If you are male and suffer from obesity, you may find that a 2-step approach to losing weight is best.First, change the type of food you eat, then reduce calories - as follows:

Step One: Change The Type Of Food You Eat
Your first step - which may last for 3-4 weeks - is to reduce your intake of high-fat and high-sugar foods, and replace them with healthier options which are lower in fat and higher in fiber. In addition, you should choose more whole grain carbs, and reduce your intake of sodium. Lastly, you should eat regularly throughout the day. No more skipping meals and snacks, or eating very little during the day. However, calorie counting is not important at this stage. What matters is that you change the type of food you consume, and eat regularly.

If you drink alcohol regularly, start reducing your intake now. There is no need to stop drinking completely, but limit your intake to no more than 2 glasses of beer or wine per day (heavy drinkers) or 1 glass per day (moderate drinkers).

By choosing healthier foods and avoiding long gaps between meals, you achieve a number of benefits. First, you reduce your "taste" for fatty, sugary and salty foods, all of which adversely affect your digestion and health. Second, you reduce cravings. Third, you improve your blood sugar levels. Fourth, you help to improve digestion. Fifth, you boost your energy levels. In addition, it is probable you will lose weight, although as stated this is not the main concern at this point.

Types Of Food To Eat (Or Avoid)

Fats
The aim is to reduce your intake of saturated, hydrogenated or trans-fats. To achieve this, please note the following:

- Limit yourself to three helpings of red meat per week.
- When eating red meat, remove all visible fat.
- Replace red meat with white or oily fish.
- Oily fish (eg. salmon, mackerel) is rich in healthy omega-3 essential fats.
- White fish (eg. cod, haddock) is rich in protein, low in fats.
- Replace full-fat cheese with reduced fat cheese.
- Use shredded cheese rather than slices.
- Switch to lower-fat dairy foods (eg. milk, yogurt)- Use butter very sparingly.
- Do not add butter, mayo or sour cream to food.
- If you are a mayo-addict, switch to very
- low-fat varieties.
- Instead, use salsa, chili sauce, lemon juice or other low-fat add-ons.

Carbohydrates
The aim is to reduce your intake of refined carbs, while increasing your intake of whole grains. Also, choose high-fiber options whenever possible. To achieve this, please note the following:

- Choose dense/chewy breads. The denser/chewier the bread, the better.
- Look for breads containing "wholewheat" or "wholegrain flour".
- Eat brown or basmati rice, rather than "instant" or white varieties.
- Eat new potatoes, rather than mashed or baked.
- Regular pasta is fine. But do not overcook. Wholewheat pasta is better.
- Avoid egg-pasta.
- Shredded Wheat, Weetabix, or any 100% wholewheat cereal is fine.
- Best cereals include oats, traditional granola/muesli.
- Avoid all frosted, candied cereals.
- For more information, see GI Diet Advice

Protein
The aim is to reduce your intake of red-meat protein, while increasing your intake of fish and vegetable protein. To achieve this, please note the following:

- Eat at least one meat-free main meal each week. Two is better.
- Include soy beans, red kidney beans or lentils in your meat-free meal.
- Eat plenty of white fish, an excellent low-fat source of protein.
- Skinless chicken fillets are also good sources of protein.
- Egg whites contain more protein than egg yolks, but no cholesterol.
- Nuts and seeds are a useful source of vegetable protein.

Fruits and Vegetables
The aim is to eat a wide variety of fruit and veggies, the wider the better. These foods are rich in antioxidants and phyto-chemicals, which improve immunity and help combat serious disease. Please note the following:

- Ideally, vegetables should occupy half your dinner-plate.
- Fresh or frozen vegetables are better than canned.
- Eat regular helpings of leafy green vegetables (eg. spinach, kale, green cabbage).
- Eat regular helpings of colored vegetables (eg. peppers, carrots, tomatoes).
- Eat regular helpings of broccoli, onions and salad vegetables.
- Aim to eat at least two medium fruits a day.
- Citrus fruits (eg. oranges, grapefruits) are rich in vitamin C.
- Apples are rich in soluble fiber, helpful in reducing cholesterol.
- Eat whole fruits (inc. chopped) rather than drink fruit juice.
- The sugar in whole fruits is harmless due to its fiber wrapping.

Step Two: Control Your Calorie Intake
Once you have managed to increase your intake of healthier foods as outlined above, you may focus on weight reduction by following a specific calorie-controlled eating plan.

Here is a sample of an 1800-calorie eating plan for men. It includes three meals and three snacks, all of which should be eaten at regular intervals throughout the day.

How Much Weight Will You Lose?
If you are male and weigh 185 pounds or more, this type of diet plan should help you lose about 2 pounds of fat per week. If you are male and weigh less than 185 pounds, you should lose about 1 pound per week.

1800-Calorie Diet Plan For Men

Breakfast [440 calories]
- Half-cup granola cereal, with chopped banana and fat
- free milk. [400 calories]
- Large slice of melon, or serving of any berries. [40 calories]

What Waist-Hip Ratio is Best?

Q. What Waist-Hip Ratio is best?
Waist-Hip Ratio and Apple/ Pear Shapes
Waist-to-hip ratio (WHR) looks at the proportion of fat stored on your body around your waist and hip. It is a simple but useful measure of fat distribution. Most people store their body fat in two distinct ways: around their middle (apple shape) and around their hips (pear shape).
var random_number = Math.random();
if (random_number
var random_number = Math.random();

To calculate your waist-hip ratio, click this calculator link:
Waist-Hip Calculator
Waist-Hip Ratio and Health Risk
Having an apple shape (carrying extra weight around the stomach) is riskier for your health than having a pear shape (carrying extra weight around your hips or thighs). This is because body shape and health risk are linked. If you have more weight around your waist you have a greater risk of lifestyle related diseases such as heart disease and diabetes than those with weight around their hips.
Waist-Hip Ratio and Obesity
Even so, overall obesity is still of greater risk than where fat is distributed or stored on your body. Other important measurements are Body Mass Index (BMI) and percentage of body fat.
How to Calculate Waist-Hip Ratio
Waist Hip Ratio is calculated by dividing your waist measurement by your hip measurement. (Hips are the widest part of your butt).
To calculate your waist-hip ratio, click this calculator link:
Waist-Hip Calculator
Best Waist-Hip Ratio for Men and Women
Ideally, women should have a waist-to-hip ratio of 0.8 or less.
Ideally, men should have a waist-to-hip ratio of 0.95 or less.

How to Calculate Body Fat

Which Body Fat Calculators Are Best
There are three main ways to calculate body fat:

  • Home Body Fat Scales
  • Skinfold Calipers (Callipers)
  • Hydrostatic Weighing

Each of these body fat calculation methods has advantages and disadvantages.


Using Home Body Fat Scales to Measure Body Fat
Body fat scales claim to measure body fat quickly and conveniently. These body fat scales use the Bioelectrical Impedance method to measure your body fat percentage. A low-level electrical current is passed through your body and the "impedance", or opposition to the flow of current, is measured. The result is used in conjunction with your weight and other factors to determine your body fat percentage. Unfortunately, your body's "impedance level" can be altered by many factors besides body fat. For instance, the amount of water in your body, your skin temperature and recent physical activity can all adversely affect the results.So only by following strict rules can you hope to get an accurate measurement of your body fat using these scales. The most important rules to observe in order to make a more accurate calculation of your body fat are:

  • Don't eat or drink for 4 hours before the body fat measurement test.
  • Don't exercise for 12 hours before the test.

Notes:

  • Some studies have shown variances as high as 8 percent when using the bioelectrical impedance method even if the rules are precisely followed.
  • As with skinfold calipers (see below) there are different equations used to calculate body fat from your body density. These are usually pre-programmed into the machine.
  • The best body fat scales tend to made by Tanita.

Using Skinfold Calipers (Callipers) to Measure Body Fat Skinfold Measurements
Measuring body fat with a set of body fat calipers is the most cost effective way to determine fat levels. But it's important to use them correctly. For instance, either have a professional take the measurements for you or buy a set of Accumeasure calipers (callipers) and follow the measuring instructions. Accumeasure are the only calipers than allow you to test yourself and most studies have shown that they are very accurate.


Using Hydrostatic Weighing to Measure Body Fat
Hydrostatic weighing (underwater weighing) is the most accurate way to calculate body fat - that is, if you can find a hydrostatic weighing tank.
How does hydrostatic weighing calculate body fat? By using Archimedes Principle. Your examiner first calculates your body density by measuring the amount of water you displace when you immerse yourself in water. Then a formula is used to calculate body fat based on your body density. The problem is finding a facility (University, major gym or fitness center) which has a hydrostatic weighing tank!!
Table 1. Body Fat Guidelines from American Council on Exercise

Women (% Fat)
Essential Fat
10-12 percent
Athletes
14-20 percent
Fitness
21-24 percent
Acceptable
25-31 percent


Men (% Fat)

18-25 percent

Why Body Fat Measurement is Important
Body fat is an important element in successful weight control. Body fat requires fewer calories than muscle. So the less fat/more muscle we have, the more calories we can eat before gaining weight. Body fat is often expressed as our "Body Fat Percentage" or "Body Fat Percent." Body fat percentage is the amount of body-fat-tissue as a percentage of total body weight. If your total body weight is 160 pounds and you have 32 pounds of fat, your body fat percentage is 20 percent.


Body Fat Calculation and Health
The higher your percentage of fat above average levels, the higher your health risk for weight-related illness, like heart disease, high blood pressure, gallstones, type 2 diabetes, osteoarthritis, and certain cancers. Also, the higher your percentage of fat (and the smaller your percentage of muscle) the less calories you need to maintain your weight and therefore the easier it is to gain weight. This is because muscle is more metabolically active than fat tissue.

Body Fat Explained

What Is The Purpose Of Storing Body Fat?
Storage of fat on the body is a critical defence mechanism. Remember, the human body has not changed essentially since the Stone Age. At that time starvation and famine were ever-present dangers to survival, while over-consumption and obesity were unheard of. To enable Stone Age humans to survive periods of food scarcity, the human body was designed to store energy which could then be drawn upon in times of famine. Thus for example, people could overeat during the hunting season, or when food was plentiful, and the surplus would be stored as fat tissue (adipose tissue). And when food was short, the body would burn the deposite fat as energy. Of course Stone Age life and body chemistry was/is much more complicated than this simple explanation suggests, but it suffices to explain why we have a built-in fat storage facility.

How Are Carbs, Protein And Fat Absorbed And Stored?
The human body needs energy to power muscles and to fuel the millions of chemical and biological reactions which take place throughout our system every day. This energy comes from the food we consume in our diet. Food consists mainly of water and three types of nutrient - protein, dietary fats and carbohydrate - which are found in varying proportions in most foods. These nutrients are broken down, digested and absorbed by the body in the gastrointestinal tract, running from the mouth to the anus. Each of these macronutrients is processed and absorbed by the digestive system in different ways.

How Are Surplus Carbs Used And Stored?
Carbohydrate is the major source of energy for the body. This is because, of all nutrients, it converts most readily to glucose which is the body's preferred fuel. When we eat carbohydrate, it is converted to glucose in the digestive tract and distributed via the liver to cells throughout the body for use as energy. Once our immediate energy needs are satisfied, the remaining carb glucose is handled in one of two ways. Either it is converted to liquid glycogen (a temporary source of readily available energy) and stored in the liver or muscles. Or, it is converted into fatty acids by the liver and stored in adipose cells (fat-cells) around the body.

How Is Surplus Protein Used And Stored?
Protein is broken down into amino acids in the stomach and small intestine, then distributed via the liver to cells throughout the body for a variety of uses included cell formation and repair. Some surplus protein amino acids are kept circulating in the bloodstream, the remainder is either converted into a type of simple sugar and used as energy, or (like carbohydrate) is converted to fatty acid and stored in adipose cells.

How Is Surplus Dietary Fat Used And Stored?
Dietary fat is broken down into fatty acids and glycerol by the stomach and small intestine. It is then distributed (in the form of triglycerides) via the lymphatic system and bloodstream to the cells for a variety of specialized uses or, in the absence of sufficient carbs, for energy. However, since dietary fat cannot be converted into protein and only about 5 percent (the glycerol part) is convertible into glucose, and because dietary fat is not the body's preferred choice of fuel, a significant amount ends up being stored as body fat in the adipose tissue.

Conversion Of Body Fat To Energy
If energy is required suddenly, the body first uses up its glycogen reserves. After this, it converts the body fat in the adipose cells into energy by a catabolic process called lipolysis. During lipolysis, triglycerides within the adipose cells are acted upon by a complex enzyme called hormone sensitive lipase (HSL). This converts the triglyceride into fatty acids and glycerol. The fatty acids are then transported via the bloodstream to tissues for use as energy, or (along with the glycerol) taken to the liver for further processing.

Adipose Tissue
Adipose cells which make up adipose tissue are specialized cells which contain and can synthesize globules of fat. This fat either comes from the dietary fat we eat or is made by the body from surplus carbohydrate or protein in our diet. Adipose tissue is mainly located just under the skin, although adipose deposits are also found between the muscles, in the abdomen, and around the heart and other organs. The location of fat deposits is largely determined by genetic inheritance. Thus it is not possible to affect where we store fat. Nor is it possible to influence from which area the body burns fat for energy purposes.

Why Do We Get Fat?
Most of us develop body fat because we eat more calories than we burn in exercise. Given a culture which emphasises "value for money food portions" and "super-sizing", along with an steady increase in serving size, an upsurge of new tasty high-calorie foods and energy drinks, such over-consumption is perhaps only to be expected. Lack of exercise is also a major contributory factor. However, overeating and lack of fitness is not the whole story.

How to lose body fat

How to Lose Body Fat
Losing body fat isn't difficult but it doesn't happen overnight. So ignore all the weight loss ads for "fat-burners" that claim you can reduce fat instantly, without effort! Such fat-loss claims are pure fantasy.

Losing Body Fat is Different from Losing 'Weight'
Note: losing fat is different from losing 'weight', because when we lose weight part of the weight loss is water and part is muscle. We're talking strictly fat-loss.

Best Way to Reduce Body Fat
Aim to lose a maximum of 1 pound of body fat per week.
Follow a low-fat diet (about 25 percent calories from fat), with plenty of fruit and veg and regular helpings of complex carbs, like whole wheat bread, oats, pasta, brown rice. Choose lower-fat meat and dairy foods where possible. Drink at least 6 glasses of water a day.
Combine this diet with regular exercise. Mix aerobic exercise with regular weight/strength-training to raise your metabolic rate and boost your lean body mass.
Take your body measurements before to start on your fat-reduction plan. Some weeks you may not lose weight, but you will lose fat, so monitoring your thighs and upper arms will boost your fat-loss motivation!

Can You Reduce Body Fat by Exercise Alone?
It's perfectly possible to lose fat simply by exercising, but it takes quite a bit of time and effort. Remember, one pound of body fat is roughly equivalent to 3500 calories.

What Amount of Exercise Burns 1 Pound of Fat?
To burn sufficient calories to lose one pound of body fat, you might:
- Briskly walk a total of 35 miles
- Swim moderately fast for 6 hours
- Dance for 12 hours
- Play about 12.5 hours of golf, carrying your own clubs
- Jog for about 29 miles

At the same time, you would need to monitor your eating habits to ensure that you are not increasing your calorie-intake in line with your increased exercise!

Be Patient When Trying to Burn Fat by Exercise
As you can see, it takes time and considerable physical effort to achieve any kind of rapid fat-loss by exercise alone. So if you want to burn off your last pockets of fat by increased fitness training, give yourself enough time and don't jump onto your bathroom scales more often than once a month. Also, be aware that muscle is denser (heavier mass) than fat. So while you may look leaner, your weight may show only a slight reduction.

Exercising Without Stretching Can Increase Bulk
Paradoxically, even though some exercise routines (eg. ab-exercises) produce a leaner look, other types of exercise (lower-body training) can make you look bulkier, especially around the thighs. To prevent this, make sure you start and finish your fitness workout with at least 5 minutes of stretching exercises to elongate the muscles worked.

Exercise Doesn't Turn Fat Into Muscle
One popular misconception is that you can convert fat into muscle by exercising. Unfortunately, this is not possible. Exercise can burn enough calories to force the body to burn fat, but it cannot turn fat into muscle. However, certain types of exercise (eg. ab-exercises) can strengthen muscles in an area of excess fat (eg. stomach) and give the appearance of a leaner shape.

La Isla De Los Pintados


Sometimes called the Forgotten Islands of Southeast Asia, located as they are off the main trading routes, the over 7000 islands that comprise the Philippines host a rich mix of about 80 to 90 distinctivelydifferent cultures, ranging from the wild sea gypsies of the Sulu Archipelago, many of whom have never stepped foot on dry land, to intensely independent Kalinga people, who live in the remote mountainous region of Northern Luzon. Here, where the terraces are close and the slopes are steep, age-old traditions are not easily changed. The few roads through the area are supplemented by narrow footpaths which wind their way along terrace edges up the jutting stepping stones of the terrace walls and through mountain passes to connect the villages and barrios. Everything, including new construction materials when needed, must be borne on human backs and heads.But one of the constants that are part of almost all traditional Filipino cultures is tattooing, with styles that range from intricately delicate swirling designs to bold and simple silhouette motifs. Tattoos have long been so much in evidence that part of the Philippines was dubbed "La Isla De Los Pintados" -- the Islands of the Painted Ones -- by Spanish explores. Sadly, over the last half-century, Filipino tattoo traditions have been slowly vanishing. For Some of the images, only a surface story can be told of their meanings, since it is believed that telling the in-depth story will diminish the tattoos worth, depriving it and its wearer of its protective power. Other tattoo designs would seem to conflict with traditional Filipino beliefs, Unless you know the thinking behind them. For example, a lizard is a messenger of death. If a lizard whispers in your ear, you won't survive the next battle. So you'd think people wouldn't be wearing a lizard tattoo, but actually the image acts as a talisman. Other messenger lizards of the spiritual world would presume that the message has already been delivered when they see the tattoo and they leave you alone. There are different tattoo traditions among each of the Philippine's main island groups; LUZON, VISAYAS, and MINDANAO. According to research, the mountain tribes in Northern Luzon developed a highly creative culture, and tattooing is still very prevalent among the people who live there. Their tattoos are intricate patterns comprised of curved and straight lines, inked in indigo blue and placed on the chest and arms. It would be difficult to find a man or woman from the interior of LUZON who has never been tattooed. But the practice is rapidly disappearing as many people are now discarding their old traditions in favor of the new.The Men of the VISAYAS, the people called PINTADOS by the Spaniards, tend to tattoo their entire bodies. The women only tattoo their hands. Both sexes get inked at an early age, as it's believed that the younger child begins to get tattoos, the easier he or she will find the experience. Visayas tattoos are extremely elaborate, they look like complicated etchings. They leave only their wrists and feet bare of ink. Basically what they do is cut the designs into the skin and then press soot or ashes into the wound. Traditional Filipino women get tattooed to enhance their beauty. Men's tattoos are markers of their age, accomplishments, and tribal seniority. Some tribes believe that tattoos have magical qualities, particularly images of scorpions, centipedes, snakes, and boats, all of which have especially deep significance to the people who wear these tattoos.The traditional tattooing method involves the tattooist smearing the skin with a mixture of soot and sugarcane juice. If sugarcane juice isn't available other substances such as lard or hen's dung can be used. The skin is then rapidly poked with the tattooing instrument, which ranges from the pointed metal pieces used by the PINTADOS, to the pieces of sharpened wood used by the kankanay tribe from Central Benguet.The Most unusual tattooing device was developed by the Isneg tribe from the Apayao Province called the "Igihisi" it is made from a curved piece of rattan with four or five pins attached to one end. The tattooist places the pins into the skin and then rapidly beats the curve next to the pins, on it's convex side, until the pins are deeply embedded into the skin. The folklore of how tattooing began in Borneo is very similar to a Philippine tattoo myth. Both are birds, who --as the story goes --fell into a bowl of black ink. Covered with pigment, the bird frantically flew into a warrior, and began to peck at him. Soon the warrior was covered with little black marks that formed a design, and the first tattoo had been inked.
