WebJan 26, 2024 · In the first category, aging is essentially an accident; an accumulation of damage and wear and tear to the body which eventually leads to death. In contrast, programmed aging theories view aging as an intentional process, controlled in a way that can be likened to other phases of life such as puberty. WebAging can be defined as a state of progressive functional decline accompanied by an increase in mortality. Time-dependent accumulation of cellular damage, namely lesions and mutations in the DNA and misfolded proteins, impair organellar and cellular function.
