    ¡¡¡¡Since the gene, called DAF-16 in worms, was found in many animals and in humans, the finding could open up new ways to affect aging, immunity(ÃâÒß)and resistance in humans, the scientists said£®

    ¡¡¡¡¡°We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits, such as immunity,¡±said Robin May of the University of Birmingham, who led the study£®

    ¡¡¡¡Populations across the world are aging at a surprising pace, bringing potentially big challenges for health and social care systems£®A study by Danish scientists last year found that half of babies born in the rich world today will live to celebrate their 100th birthdays£®Scientists are eager to find out how people age to try to develop drugs to help them stay healthier as their lives extend£®

    ¡¡¡¡¡°What we have found is that things like resistance and aging tend to go hand in hand,¡±May said in an interview£®

    ¡¡¡¡May's team compared longevity, stress resistance and immunity in four related species of worm£®They also looked for differences in the activity of DAF-16 in each of the four species, and found that they were all quite distinct£®

    ¡¡¡¡May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes, which scientists believe play a role in the aging process£®

    ¡¡¡¡¡°The fact that subtle(΢ÃîµÄ)differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and may explain how differences in lifespan and related traits have arisen during evolution,¡±May said£®

When did eating butter become a sin, and a little bit of extra flesh unappealing, if not repellent? All religions have certain days when people refrain from eating and excessive eating is one of Christianity's seven deadly sins£®However, until quite recently, most people had a problem getting enough to eat£®In some religious groups, wealth was a symbol of probable salvation and high morals, and fatness a sign of wealth and well£­being£®Today the opposite is true£®We have shifted to thinness as our new mark of virtue£®The result is that being fat ¨Cor even only somewhat overweight£­is bad because it implies a lack of moral strength£®

    ¡¡¡¡Our obsession(ÃÔÁµ)with thinness is also fueled by health concerns£®It is true that in this country we have more overweight people than ever before, and that, in many cases, being overweight correlates with an increased risk of heart and blood vessel disease£®These diseases£®, however, may as much to do with our way of life and our high£­fat diets as with excess weight£®And the associated risk of cancer in the digestive system may be more of a dietary problem£­too much fat and a lack of fiber£­than a weight problem£®The real concern, then, is not what we weight too much, but that we neither exercise enough nor eat well£®Exercise is necessary for strong bones and both heart and lung health£®A balanced diet without a lot of fat can also help the body avoid many diseases£®We should surely stop paying so much attention to weight£®Simply being thin is not enough£®It is actually hazardous if those who(or already are)thin think they are automatically healthy and thus free from paying attention to their overall life£­style£®Thinness can be pure vainglory(ÐéÈÙ)£®

    ¡¡¡¡From a very early age, some children exhibit better self-control than others£®Now, a new study that began with about 1,000 children in New Zealand has tracked how a child's low self-control can predict poor health, money troubles and even a criminal record in their adult years£®

    ¡¡¡¡Researchers have been studying this group of children for decades now£®They observed the level of self-control the youngstrrs displayed£®Parents, teachers, even the kids them-selves, scored the youngstrers on measures like¡°acting before thinking¡± and ¡°Persistensce in resching goals£®¡±

    ¡¡¡¡The study led by Moffitt of Duke University and colleagues followed 1,000 children from birth to age 32 in Dunedin, New Zealand£®

    ¡¡¡¡¡°The children who had the lowest self-control when they were age three to ten, later on had the most health problems in their 30s,¡± Moffitt said, ¡°and they had the worst financial situation, They were more likely to have a criminal record and to be raising a child as a sin-gle parent on a very low income£®¡± Moffitt explained that self-control problems were widely observed, and weren't just a feature of a small group of misbehaving kids£®

    ¡¡¡¡Moffitt said it's still unclear why some children have better self-control than others, though she said other resesrchers have found that it's mostly a learned behavior, with rela-tively little genetic influence£®But good self-control can be set to run in families because chil-dren with good self-control are more likely to grow up to be healthy and prosperous parents£®But the good news, Moffitt said, is that self-control can be taught by parents, and through school curricula that have been shown to be effective£®
