Aging is an unregulated process, unlike biological systems. This perspective suggests aging results from accumulated metabolic damage, leading to inevitable death in complex organisms like humans.

Area of Science:

  • Gerontology
  • Cellular Biology
  • Evolutionary Biology

Background:

  • Aging is often viewed as a regulated biological process.
  • However, the lack of consistent death causes and the susceptibility of regulated systems to aberration challenge this view.
  • Rejuvenation is observed in simpler organisms but suppressed in humans, where aging is irreversible.

Purpose of the Study:

  • To propose aging as an unregulated process.
  • To introduce the exhaustion theory of aging.
  • To explain the inevitability of aging and death in developed animals.

Main Methods:

  • Comparative analysis of aging across different species.
  • Observational study of aging and death patterns.
  • Theoretical framework development based on metabolic processes.

Main Results:

  • Aging and death are not subject to regulatory mechanisms, unlike other biological systems.
  • The cause of death varies widely within species, indicating a lack of regulation.
  • Rejuvenation is present in lower animals but absent in humans, correlating with aging's irreversibility.

Conclusions:

  • Aging is an unregulated biological process.
  • The exhaustion theory posits that accumulated metabolic insults lead to system failure and death.
  • This perspective explains the inevitability of aging and death in humans.
