Humans have been on the earth for 300 millennia.
If we're being VERY generous, we've consistently lived past 40 for the last 2,000 years.
So for 99.33% of human history the ONLY leaders we had were under 30.
- Kamq 4y ago> If we're being VERY generous, we've consistently lived past 40 for the last 2,000 years. That's not... that's not how statistics work work at all. Life expectancy was 30 because half of all babies died, and on top of that childhood diseases took out a bunch more. Eliminating this has been the vast majority of life expectancy increase. If you made it to puberty in antiquity, you were pretty likely to make it to 60 or so. Y'know... assuming you didn't live in an area the Romans or Mongols wanted.
- drekipus 4y agoDo you have any sources on that? It l that's an interesting way to look at it. I would have expected life expectancy to be way lower than you suggest by your calculations. (IE: 9/13 babies died*, with 60 as full life, meaning 18 yrs expectancy). * All I know is that humans used to produce a lot of babies because a lot of them would die, but my googling sucks
- andsoitis 4y agoLots to read at https://en.wikipedia.org/wiki/Life_expectancy https://en.wikipedia.org/wiki/Life_expectancy such as: Until the middle of the 20th century, infant mortality was approximately 40–60% of the total mortality. Excluding child mortality, the average life expectancy during the 12th–19th centuries was approximately 55 years. If a medieval person survived childhood, they had about a 50% chance of living 50–55 years, instead of only 25–40 years.
