WASHINGTON (AFP) The researchers studied a population of Ashkenazi Jews who have lived to age 95 and older and found that their eating and lifestyle habits were no better than those of the general population. In fact, men in the long-lived group drank slightly more and exercised less than their average counterparts, said the findings in the online edition of Journal of the American Geriatrics Society. This study suggests that centenarians may possess additional longevity genes that help to buffer them against the harmful effects of an unhealthy lifestyle, said senior author Nir Barzilai, director of the Institute for Aging Research at Yeshiva Universitys Albert Einstein College of Medicine.
