Longevity
In the field of demography, longevity is synonymous with life expectancy. And in layman’s term, it means “how long will a person or a thing live or survive.” Further, scientists are still studying how to prolong or extend a person’s life since everyone acknowledges that life indeed is too short. Further, longevity has been a topic not only for the scientific community but also for writers of science fiction, travel, as well as utopian novels. There are a lot of factors to consider in knowing one’s longevity such as the lifestyle, habits, attitudes, etc. and the current lifestyle of individuals has indicated that longevity is shortened.
