During the aging process, natural biological changes occur within the body. Although no single measurement can predict how long you will live, the rate at which aging changes take place depends on a combination of genetic and lifestyle factors. Your lifestyle habits determine to a great extent how your genes affect your aging process. Hundreds of research studies point to critical lifestyle behaviors that determine your statistical chances of dying at a younger age or living a longer life. Research also shows that lifestyle behaviors have a far greater impact on health and longevity than genes alone.
