Sleep better, live longer with the groundbreaking information and step-by-step program in this revolutionary book.Healthful sleep has been empirically proven to be the single most important factor in predicting longevity, more influential than diet, exercise, or heredity.

And he offers a hands-on prescription for vibrant good health and longevity, including...self-tests to determine how much sleep you really need...the role of prescription and over-the-counter sleeping aids...the latest research on how sleep affects the immune system...how to combat insomnia, snoring, and jet lag...plus information on sleep disorder clinics nationwide, Web sites, and more.Taking readers on a fascinating tour of our sleeping body and mind, Dr. William C.
