Who Wants to Live Forever? Dr. Stephen Coles on the Secrets of the World's Oldest People

UCLA's Dr. Stephen Coles studies the oldest people in the world. Hitting the century mark isn't enough to pique his interest because Coles' research focuses on supercentenarians, that is, those at least 110-year-old. Today Coles recognizes only 88 people worldwide as supercententarians, and the list is available at the Gerontology Research Group website (www.grg.org).

Dr. Coles sat down with Reason.tv's Ted Balaker to explain why supercententarians live so long, what eventually does them in (it's not old age), and what could be done to help them (and the rest of us) live longer lives.
