Long life is humanity's ancient and perennial goal. Prophets promised it, explorers searched for it and today's society is obsessed with it. Today's panelists discuss the biology of aging and debate the facts, fads and fallacies of living longer -- and offer the best, most sensible advice to slow the aging process. Joining host Robert Lawrence Kuhn are gene therapist French Anderson; fitness theorist Arthur S. De Vany; best-selling author and surgeon Sherwin Nuland; biophysicist Gregory Stock; and longevity expert Roy Walford.
