The surprising reality of increased human life expectancy.
The surprising thing is, people throughout history, and before, lived longer than is often depicted.
From the 1500s till around 1800, life expectancy throughout Europe hovered between 30 and 40 years of age, then the 20th century, life expectancy rose from 49.2 to 80.3 years.
The surprise is, throughout history and as long as far back as we can know, a full lifespan has always been around 70 years or longer. The biggest change has not the length of a human lifespan, but instead, the dramatic increase in percentage of people who get to enjoy that lifespan.
