Michio Kaku is one of the world's most renowned scientists, has written 7 books and has appeared in countless scientific television programs and films, as well as hosting his own scientific radio show. In this fascinating and illuminating video, he explains what science knows about the aging process, and how it might be reversed or at least slowed down in the near future.
It may sound like science fiction, but aging itself is nothing more than the accumulation of problems in our cells, which usually repair themselves, but as they get older, fail more and more to do so. This is why we start looking and feeling old. But if we can help our cells in their repair works, maybe we can slow down this process we call aging.
