Aging is a biological process that affects every cell, organ, and system in the body, yet much of what happens along the way remains poorly understood by most people.Aging is a biological process that affects every cell, organ, and system in the body, yet much of what happens along the way remains poorly understood by most people. This book explains the science behind growing older, from cellular changes and DNA repair to the gradual decline of organ function and the immune system. You will learn what current research reveals about the biological mechanisms of aging, the factors that influence how quickly it progresses, and the difference between normal aging and disease. The book also addresses common misconceptions and summarizes what scientists do and do not yet know. This book was generated using artificial intelligence, drawing on established scientific sources to present a clear, factual introduction. It offers you a solid, accessible overview of the aging process, written for readers with no prior background in biology or medicine.Aging is a biological process that affects every cell, organ, and system in the body, yet much of what happens along the way remains poorly understood by most people.
