DNA is "life's blueprint", encoding our genetic inheritance for health and life expectancy. Throughout life, DNA reproduces and replaces itself continually. In optimal conditions, DNA copies itself, making perfect reproductions. But as people age and their DNA is gradually damaged by the environment, diet, and physical and emotional stress, the DNA begins to reproduce poorly and ultimately stops reproducing completely. The result is disease and aging. In this groundbreaking book, Vincent Giampapa, MD, presents a radical new theory on how we age.
