> Why do you think how to live healthy is a modern invention? Don't you think people had to figure that out ages ago, or else we wouldn't be here? Not really, no. They had many ideas about health that we know are false now. And we still don't know a lot. Generally people died really young in those days. But these things don't really matter for the population continuity if people get sick after they get kids, and they used to have them really early in those days (and many). They just didn't usually live until their 90s. And of course knowing how to live healthy and actually doing it are different things too. It's something we really struggle with as a society and me too.
