Longevity refers to the length of time an individual lives, often measured by life expectancy, which is the average number of years a person can expect to live based on statistical analysis. It encompasses not only the duration of life but also the quality and health during those years.

Longevity is closely tied to the concept of healthy aging, which emphasizes maintaining physical, mental, and social well-being as one grows older. This includes managing chronic conditions, staying active, and preserving cognitive function.

 As people live longer, the prevalence of chronic diseases such as heart disease, diabetes, and arthritis increases. Effective management of these conditions is crucial for maintaining quality of life in older adults.

 Increased longevity puts pressure on healthcare systems to adapt, necessitating more resources for elderly care, advanced medical treatments, and preventive measures.
