Summary

Hydrogen sulfide (H(2)S) may extend lifespans by slowing metabolism, potentially enabling people alive today to reach engineered negligible senescence (ENS). This breakthrough offers a bridge to future life extension technologies.

Area of Science:

  • Biogerontology
  • Metabolic research
  • Toxicology

Background:

  • Engineered negligible senescence (ENS) is a theoretical future possibility in biogerontology.
  • Significant disagreement exists regarding the timeline for achieving ENS.
  • Current projections suggest ENS is unlikely within the lifespan of most individuals alive today.

Purpose of the Study:

  • To explore potential interventions that could extend human lifespan until ENS becomes achievable.
  • To investigate the effects of hydrogen sulfide (H(2)S) on mammalian metabolism and longevity.

Main Methods:

  • Review of existing biogerontological theories on aging.
  • Analysis of recent findings on the physiological effects of low-level hydrogen sulfide (H(2)S) exposure in mammals.
  • Extrapolation of potential lifespan extension based on metabolic rate reduction.

Main Results:

  • Low levels of hydrogen sulfide (H(2)S) appear to regulate the internal thermal rheostat in mammals.
  • This regulation results in a slowed metabolic rate.
  • The observed effects suggest a potential mechanism for near-term lifespan extension.

Conclusions:

  • Hydrogen sulfide (H(2)S) may offer a method to extend lifespan for current generations.
  • This extension could provide a crucial window to benefit from future engineered negligible senescence (ENS).
  • Further research is warranted to confirm the safety and efficacy of H(2)S for human longevity.
