# Centenarian

A centenarian is a person who has reached the age of 100 years or more. Centenarians are a key research population in longevity science because they typically delay or escape major age-related diseases. Studies such as the New England Centenarian Study and Japan's Okinawa Centenarian Study examine genetic, lifestyle, and environmental factors associated with exceptional human lifespan and healthspan.
