Longevity

Longevity refers to the length of time that an individual or organism lives. It is often used in the context of human lifespan, indicating not just the duration of life but also the potential for a long, healthy life free from major diseases or disabilities. Longevity can be influenced by a variety of factors including genetics, lifestyle choices, environmental conditions, and societal influences. Studies of longevity often examine populations known for their extended lifespans, such as those in “Blue Zones” where people live significantly longer than average. Researchers investigate the biological and social factors that contribute to a longer life, including diet, physical activity, social engagement, and mental health. In broader contexts, longevity can also apply to the duration of non-living entities, such as products or technologies, reflecting their durability and effectiveness over time.
