WebOct 10, 2024 · While most researchers don't agree with programmed aging, they do undertake research that is more in accordance with programmed aging than with the view of aging as damage. The strategy doesn't match to the vision of aging, for reasons that have a lot to do with the way in which clinical development is regulated. WebThis isn't a dumb question at all. I've actually read chapters dealing with this exact topic. The answer is: in some ways, yes, others, no. For example, the Hayflick limit says how many times a cell can divide before its telomeres become too short and the cell will die, but we also have genes for telomerase which can extend the telomeres and survive much longer.

WebJan 1, 2024 · Aging theories can be subdivided into two groups – theories of stochastic aging and theories of programmed aging. Theories of Stochastic Aging The somatic mutation theories of aging belong to the group of stochastic theories, i.e., non-programmed aging theories since mutations are random damages (Medawar 1952 ; Szilard 1959 ). WebNov 1, 2015 · Genetic, or programmed theories, propose that aging is genetically determined and organisms have an internal clock that programs longevity. Damage theories, sometimes referred to as stochastic theories, propose that chance error and the accumulation of damage over time cause aging.
