Aging by Design: How New Thinking on Aging Will Change Your Life
Why do we age? How do we age? These questions have baffled scientists for centuries and remain unresolved. The answer to the ‘how’ question is critical to our ability to successfully prevent and treat age-related diseases like cancer and heart disease that now cause the majority of all deaths in the developed world.Because of major difficulties in experimentally determining causes of aging, the answer to the ‘why’ question is critical to guiding research efforts directed toward identifying and altering processes involved in age-related diseases.
Evolution theory plays a critical role in determining why we age because it attempts to explain why each living organism has its particular design and therefore why different species display different aging characteristics and different life spans. This short book describes the history and current status of attempts to explain why we age extending from Darwin’s 1859 theory to the present.
