lifespan extension theories

Lifespan extension theories explore ways to increase the human lifespan and improve health in old age. Key concepts include caloric restriction, which suggests that reducing calorie intake without malnutrition may slow aging; genetic factors that influence lifespan; and the role of cellular repair mechanisms that maintain health. Other theories focus on the impact of lifestyle choices, such as diet, exercise, and stress management. Emerging research also investigates compounds like NAD boosters and senolytics, which may help remove aging cells. Overall, these theories aim to understand the biological processes of aging and identify interventions to promote healthier, longer lives.
