By Dr. Andrew Weil. Dr. Weil has been an authoritative and companionable guide through a uniquely effective combination of traditional and nontraditional approaches to health and healthy living. Now he gives us a book about aging that is unlike any other in the breadth and depth of its information and understanding. At the heart of Healthy Aging is Dr. Weil’s belief that although aging is an irreversible process, there are myriad things we can do to keep our minds and bodies in good working order through all phases of life. To that end, he draws on the new science of biogerentology (the biology of aging) as well as on the secrets of healthy longevity—diet, activity, and attitude—that he has gathered firsthand from cultures around the world. Informative, practical, and uplifting. 304 pages, hardcover.
