Psychology of Longevity
Longevity denotes especially long-lived members of a population. It is separated from life expectancy which focuses on the likely mean age of death within a population.
There is no overarching theory of aging and longevity or a specific psychological theory targeting longevity as the main outcome. Survival into advanced ages is determined by multiple influences of genes interacting with environmental conditions over the entire life span. Already from embryonic life, individual experiences and behavior influence health, functioning, and the likelihood for longevity. To capture all these dimensions in a single theory seems impossible.
Biological theories focus on evolutionary aspects and underlying mechanisms for life and typically define longevity as the potential life span under ideal conditions. Foci in social theories are contextual influences related to survival, especially the socioeconomic environment that humankind...
