Despite recent advances in molecular biology and genetics, the mysteries that control human lifespan are yet to be unraveled many theories, which fall into two main categories: programmed and error theories, have been proposed to explain the process of aging, but neither of them appears to be fully. Abstract: many theories have been proposed to answer two questions on aging: why do we age and how do we age among them, evolutionary theories are proposed to interpret the evolutionary advantage of aging, and saving resources for group benefit is thought to be the purpose of aging.

Modern theories of biological aging in humans and other mammals fall into two categories: programmed theories, also known as adaptive or active theories contend that organisms are designed to have a genetically programmed limited life span because aging and consequently limited life span serves some evolutionary.

Each of these theories has focused on one or two key elements thought to profoundly affect the aging experience the purpose of this essay is to analyze these theo- retical developments for their specific contributions and identify the theoretical prerequisites of an adequate theory of aging in so doing, i advance three.

The activity theory, also known as the implicit theory of aging, normal theory of aging, and lay theory of aging, proposes that successful ageing occurs when older adults stay active and maintain social interactions it takes the view that the aging process is delayed and the quality of life is enhanced when old people remain.
