Survival and longevity improvements at extreme ages: an interpretation assuming an ecological stress theory of aging.

Biogerontology - 1 Apr 2007

Parsons Peter A

Abstract excerpt

The primary determinant of survival during aging is the energetic efficiency and metabolic stability required to counter the accumulated internal and external stresses of a lifetime. Hence, genetically stress-resistant individuals should accumulate with age; frailer, less robust, less energetically efficient and less metabolically stable individuals should succumb in parallel. This selection process implies the...
