aging theory

Aging theory explores why and how living organisms change over time, leading to gradual decline in function and increased vulnerability to disease. It suggests that aging results from biological processes like cell damage, genetic mutations, and wear and tear of bodily systems, often due to accumulation of harmful byproducts and reduced ability to repair damage. Different theories emphasize factors such as genetic programming for lifespan, environmental influences, or the body's decreasing efficiency, helping scientists understand the complex, multifaceted nature of aging and identify potential ways to promote healthy longevity.
