Telomeres May Hold Clues To Effects Of Aging

Scientists are reporting an advance in the science of aging — and maybe even a clue on how to reverse some of aging's effects. They have evidence that lifestyle changes already known to be good for you — healthy diet, exercise, reducing stress — may prevent the chromosomes in our cells from unraveling. It's all about little caps on our chromosomes called telomeres.
