The Wear and Tear Theory of Aging. The wear and tear theory of aging believes that the effects of aging are caused by damage done to cells and body systems over time. Essentially, these systems wear out due to use. Once they wear out, they can no longer function correctly.
Two major theories explain the psychosocial aspects of aging in older adults. Disengagement theory views aging as a process of mutual withdrawal in which older adults voluntarily slow down by retiring, as expected by society. Proponents of disengagement theory hold that mutual social withdrawal benefits both individuals and society. Activity theory, on the other hand, sees a positive correlation between keeping active and aging well. Proponents of activity theory hold that mutual social withdrawal runs counter to traditional American ideals of activity, energy, and industry.
