Supercentenarian

A supercentenarian is a person who has reached age 110. Verified cases are rare, and claims at these ages require unusually strong age documentation.

Gerontology: The scientific study of aging and older adults. Supercentenarians are studied as an exceptionally long-lived group.
Biological aging: The progressive biological changes associated with increasing age. Survival to 110 entails enduring age-related changes far beyond typical lifespans.
Jeanne Calment: A French woman whose lifespan of 122 years and 164 days is the longest widely accepted human lifespan. Her extensively documented case anchors modern discussions of extreme longevity.
Maximum human lifespan: The greatest age humans can reach, whether as an observed record or a biological limit. Supercentenarian cases inform debate over whether human lifespan has a fixed ceiling.
Human longevity: The duration of human life, considered across individuals or populations. Supercentenarian status marks an extreme point in the human lifespan.
Cellular senescence: A state in which cells stop dividing while remaining metabolically active. Senescent cells accumulate with age and are studied in longevity research.
Kane Tanaka: A Japanese woman who lived from 1903 to 2022 and was recognized as a supercentenarian. Her verified lifespan illustrates a well-documented case from the twenty-first century.
Longevity escape velocity: A proposed point at which medical progress extends life faster than aging causes damage. It contrasts current exceptional survival with speculative future extensions of lifespan.
Age validation: The process of checking documentary evidence for a person's claimed age. Birth and later-life records determine whether a reported case is accepted.
DNA damage theory of aging: The view that accumulated DNA damage contributes to functional decline with age. It offers one mechanism researchers investigate in exceptionally long-lived people.
