The disputed late-life mortality deceleration law states that death rates stop increasing exponentially at advanced ages and level-off to the late-life mortality plateau. An immediate consequence from this observation is that there is no fixed upper limit to human longevity — there is no special fixed number , which separates possible and impossible values of lifespan.

Biodemographic studies  found that even genetically identical laboratory animals kept in constant environment have very different lengths of life, suggesting a crucial role of chance and early-life developmental noise in longevity determination. This leads to new approaches in understanding causes of exceptional human longevity.
