>> P3. Paleolithic humans successfully reproduced in an environment without modern medicine

Many paleolithic humans did not successfully reproduce. Many died before being able to. Humans continued to exist because enough successfully reproduced.

Unless your personal health goal is that a sizable proportion of your cohort survive to reproduce successfully, this is not particularly helpful reasoning.

In any event, you are highly likely to make it to child-rearing age in economically developed countries. Our health problems occur later.
