Healthy Life Expectancy

[Blade Runner]

If you watch from about 6 minutes to 9 minutes the guy actually explains that the "blue zones" of health where there are a high percentage of centenarians are fake based on flawed data. Those places historically had various incentives to lie about your age plus during certain time periods a lack of birth certificates or birth certificates destroyed during wars etc. The population above 90 in the blue zones is actually below average compared to other places.

The other thing dumb about the blue zone stuff is that it's just modern history bias and peace time bias. You think people in those "blue zones" were living to 90-100 "stress free" lives in 1820? LOL

The idea that the world as it is, will stay the way it is, is one of the dumbest things that fools humans all the time. But we do have relatively short lifespans in the greater scheme of things, so we're blinded by a lot of this stuff. Ironically, people can barely detect societal and global propaganda over even 30 years of their own lives (global cooling, warming, egalitarianism, feminism, social programming, fiat money, etc).

While there is no reliable data - but it seems certain that throughout history there were periods were there were surprisingly large percentage of people reaching the age of 100 and sometimes beyond.
Child mortality rates were high historically. However, children who reached the age of 12 usually had very very strong immune systems. Such people
often lived long (excluding variable factors such as wars, natural disasters, major epidemics etc). .
