How do you calculate life expectancy?

Answer by  steve12 (342)

This is a very difficult question, and depends what you understand by life expectancy. If you mean for the general population, than it's statistical measure, but if you mean about an individual's life expectancy, than many factors must be taken in account, such as the habits, diseases, vaccines, genetics, etc.

Life expectancy is based on many things. Look at your family history - if your family members have lived for a long time, you'll be more likely to live for a long time. Also, your lifestyle has to be taken into account. Smoking, unprotected sex, working as a coal miner - can all account for a shortened life expectancy.

There are life expectancy calculators that you can use on the internet. They take into account things like your lifestyle habits (such as whether or not you smoke or drink) as well as hereditary factors (such as if your parents have diabetes, heart disease or other hereditary diseases that you may be prone to.)
