Well I regret having to answer you with a boutade (later they say that I do not give "serious" answers) ... but it will depend on which person .
Life expectancy is the (average of) number of years that a person, population, city or country lives in a certain period. It is usually divided into masculine and feminine , and is influenced by factors such as the quality of medicine, hygiene, wars ... although today it usually refers only to people who have a non-violent death.
Therefore it is easy to assume that the life expectancy of a person born in Japan is not equal to that of a person born in South Sudan.
The world average is 71.4 years (in 2015), but there are great differences between different regions.
- In Europe and North America the average is 73 years
- In Oceania, 71 years old
- In Latin America of 70 years
- In Asia of 61 years
- In Africa of 55 years.
