Wear and tear theory of aging?

The wear and tear theory of aging suggests that the body experiences damage and deterioration over time due to cumulative damage from environmental stressors, leading to the aging process. This theory proposes that the body's cells and systems become less efficient at repairing and maintaining themselves as they age, contributing to the signs of aging and declines in health. However, this theory is not universally accepted, as other factors such as genetics, lifestyle, and metabolic processes also play a role in aging.
