Document Summary
Human behavior involves physical, psychological, and social factors. Nature and bio- psychological interrelationships change as aging occurs. Each individual remains a unique and complex being throughout life and can only be properly understood from a holistic perspective. No single theory is acceptable to explain the complex aging process: much research involves subhuman species making it difficult to generalize to the human race. Biological theories: stochastic and non-stochastic: stochastic theories: view aging as caused by a series of random adverse changes in the cells occurring overtime and leading to replicative errors. Wear and tear theory: (older theory) assumes that continued use leads to worn out or defective parts of the body. Further affected by accumulation of byproducts detrimental to cells" and tissues" functioning. This theory ignores the various repair mechanisms of the body and the fact that in certain areas (i. e. , muscle) continued use increases strength and functioning. Error theory: cumulative mistakes occurring in dna and.
