>>510873512That's a bit optimistic buddy. Diseases won't disappear alongside medicine.
Instead the reason you don't get sick is:
>everybody else died, so you are alone and there's nobody who could infect youBesides animals that is, and mosquitos and whatever, maybe a tick? Then there's parasites.
The reason why there are no cripples in such a healthy, natural society is... that they died. Same is true for anything else.
>something wrong with you?>you're already deadThat naturally leaves only more or less healthy people, but your population will drop to 0.1% as everybody dies, and then stabilizes as you jog through the forest half naked as a hunter gatherer.
