The Problem With Life Expectancy

Rather interesting video on the problems with how modern scholars calculate life expectations. And why when people throw out texts saying people used to live longer by citing stats from the 1800s saying the life expectancy was 30 or 40 years old are moot, since the main reason the life expectancy was recorded as so low back then was because of extremely high infant mortality rates, rather than you’re 40 years old and are an old man.


It was good, but it does not explain the wild larger lifespans of humans. But it was still quite good and some new information as well.


I have not had a chance to watch it yet, but the life expectancy was that number largely because of the amount of infant mortalities that occurred and the amount of children that did not make it passed five years old due to diseases and/or lack of medical treatment, etc. The life expectancy is an average. Many people who made it into adulthood lived well into old age.
