Life Span

Lifespan refers to the duration of time that an individual organism lives, from birth to death. It varies significantly across species; for instance, humans typically live around 70-90 years, while certain tortoises can live over a century. Lifespan is influenced by factors like genetics, environment, lifestyle, and healthcare. It's important to differentiate between lifespan and life expectancy, which is the average age individuals within a population are expected to live. Understanding lifespan helps in research related to health, aging, and disease prevention, providing insights into how to improve quality of life across different ages.
