Theories of Aging
Identify the different theories and their implications on the aging process.
The aging process has been studied extensively, and several theories have been proposed to explain the mechanisms behind it. These theories can be broadly categorized into two groups: programmed theories and damage or error theories.
Programmed Theories
Programmed theories suggest that aging follows a biological timetable, perhaps a continuation of the one that regulates childhood growth and development. These theories include:
- Programmed Longevity Theory
- Implication: Aging is the result of a sequential switching on and off of certain genes, with senescence (the process of deterioration with age) being defined as the time when age-associated deficits are manifested.
- Biological Perspective: Genes play a primary role in determining lifespan, suggesting that certain genetic programs control the aging process.
- Endocrine Theory
- Implication: Biological clocks act through hormones to control the pace of aging…
