Summary
This study reviews human mortality data, finding variations in the Gompertz parameters and questioning the concept of maximum lifespan. Simple stochastic models may explain the Gompertz law, warranting further biological research.
Area of Science:
- Demography
- Experimental Gerontology
- Biostatistics
Background:
- Mortality dynamics are central to demography and gerontology.
- The Gompertz-Makeham function is a foundational model for mortality analysis.
- Secular and topological variations in Gompertz parameters are observed in human vital statistics.
Purpose of the Study:
- To review variations in Gompertz parameters across human populations.
- To critically examine the concept of maximum lifespan.
- To explore theoretical backgrounds for the Gompertz law using stochastic models.
Main Methods:
- Comparative analysis of human vital statistics.
- Literature review of existing studies on mortality and aging.
- Application of stochastic models to Gompertzian mortality.
Main Results:
- Observed characteristic secular and topological variations in Gompertz parameters.
- Challenged the unambiguous nature of male mortality excess.
- Identified simple stochastic models as potential theoretical underpinnings for the Gompertz law.
Conclusions:
- The Gompertz law's parameters exhibit significant variations.
- The concept of a fixed maximum lifespan is debatable.
- Stochastic models offer a promising theoretical framework for Gompertzian mortality, requiring further validation.
