Using today's most leading-edge therapies and breakthroughs in the science of longevity, this book shows how we can healthfully age to one hundred, and beyond. By following commonsense habits, we can expect an average lifespan of one hundred years. Adding the life-enhancing effects of natural DHEA restoration, stress reduction, meditation, reduced caloric intake, and a range of mind/body techniques may, however, give us another forty years of active, healthy living. Therein lies the available "fountain of youth."
