Have been reading a book called The Shwarzbein Principle. Suzanne Somers went to this doctor. Have been thinking that so much of aging is related to diet and exercise..... Shwarzbein says you're either building up or breaking down. There is an element of aging that has to do with endocrinology; how you eat is affecting how well your body will look and function when you get older.
The co-author of the Shwarzbein book is named Nancy Deville. She is 60, looks a lot younger. Her book, Healthy, Sexy, Happy is released today.
