>>124233>>124235I can't get over how wrong all of this is.
Life expectancy up until the last thousand years was 30 or less, as an average (mostly because of ridiculously high infant mortality rates).
Evolution does not and can not be stopped, by definition.
You're confusing immune systems with micro-organisms inside the digestive tract.
Also, people didn't "really live?" The amount of leisure time that a hunter-gatherer had is a hell of a lot more than you or I do.
Human anatomy has NOT atrophied. Our nutrition is ridiculously better, and our bodies are insanely better-developed.
The only thing that you're really refering to is the fact that our bodies used to be able to process certain types of food and water that they can't, any more, because the way that our bodies processed those things were by relying on tiny little bugs in our guts. And the kinds that processed the things that you're talking about? They don't live in our guts, any more. But different ones do, and if you took your oh-so-strong cave-folk and put them in our world? They'd shit themselves to death trying to cope with our food and water (well, they would if we didn't have modern medicine that can easily overcome the obstacles that their poop-producers would encounter).
