What are the example of wear and tear theory?

The wear and tear theory posits that aging is a result of cumulative damage to cells and tissues over time. Examples include the gradual decline in the function of organs, such as the heart and kidneys, due to oxidative stress and cellular damage. Additionally, the theory explains the deterioration of joints, leading to conditions like osteoarthritis, as well as the aging of skin, resulting in wrinkles and loss of elasticity. Overall, it emphasizes the impact of environmental factors and lifestyle on biological aging.
