Deepak Chopra's Ageless Body, Timeless Mind sold a million copies in hardcover and was, for many Americans, a primer on the vital interconnections between mind, body, and spirit. The author puts the accent on the positive as he talks about the link between belief and biology, the value of adaptability, the defeat of entropy, ways to practice the balance of life, and the use of meditation to combat aging.

Chopra ranges far and wide in this onslaught on our traditional view of aging. He mixes illustrative material from research at Harvard, Duke, and Stanford with insights gleaned from Eastern religions. "In order to stay alive, your body must live on the wings of change," Chopra notes. Yes, and this paperback shows how.
