Aging from Biologic, Sociologic, and Psychological Perspectives
Aging is a complex process that involves physical, social, and mental changes over time. Various theories have been developed to explain the biological, sociological, and psychological aspects of aging.
1. Biological Aging
Biological aging refers to the physical and physiological changes that occur in the body over time. It is the process by which cells, tissues, and organs gradually lose their functional capacity and efficiency.
- Theories:
- Programmed Theories: These theories suggest that aging is genetically programmed. One example is the Gene Theory, which proposes that specific genes are responsible for aging, controlling the growth and repair of cells.
- Damage or Error Theories: These theories assert that aging results from the accumulation of cellular damage over time. One example is the Free Radical Theory, which suggests that oxidative damage from free radicals (unstable molecules) accelerates the aging process.
- Telomere Shortening: Telomeres, protective caps at the end of chromosomes, shorten with each cell division. Over time, this leads to cell dysfunction and death, contributing to aging…
