what is the theories of aging
Psychosociological theory. In addition to theories of aging based on molecules and cells, there also exists a âpsychosociologicalâ theory of aging. As people grow older, their behaviour changes, their social interactions change, and the activities in which they engage change.
Biological theories of aging. Aging has many facets. Hence, there are a number of theories, each of which may explain one or more aspects of aging. There is, however, no single theory that explains all of the phenomena of aging. Genetic theories
The âsomatic mutationâ theory of aging assumes that aging is due to the gradual accumulation of mutated cells that do not perform normally. Nongenetic theories. Other theories of aging focus attention on factors that can influence the expression of a genetically determined âprogram.â
