David Stipp is the ideal ambassador to the sometimes surreal landscape of life extension. How is it possible to understand so much, to explain so clearly, to tell a story so engagingly and so well? I hope he keeps writing books until he's 300 years old. (And guess what? It's not entirely out of the question!) --MARY ROACH, bestselling author of Stiff, Spook, and Bonk Well-researched, excellent book on the progress of the biology of aging. --Robert N.
