Longevity and Life Expectancy

Longevity refers to the length of time a person lives, while life expectancy is the average number of years a group of people is expected to live, often determined by factors like healthcare, lifestyle, and environment. In the context of an aging population, both concepts highlight the growing number of older individuals in society. As healthcare improves, people tend to live longer, leading to increased life expectancy. This shift presents challenges and opportunities for healthcare systems, economies, and social structures, as communities must adapt to support an older population with unique needs and contributions.
