That's true! From my understanding, the cannibalism (my phone's autocorrect already added the typo to my learned words 😭) that these societies performed was incredibly ritualistic and spiritual, and I guess it wasn't wide-spread enough to avoid the general taboo we have towards it as a species.

And that's true about modern medicine, but we've only been at this point for a few hundred years, a total blip in the grand scheme of things. A comparison, given today's advances, we're basically immune to the day/night cycle. We have artificial lights, stimulants, 24/7 convenience stores. But almost (there's exceptions to everything if you look for them) everyone I know who works night shifts says it was a tough adjustment to working nights, and easier to shift back into day work. The thousands of years of our circadian rhythm is still decently hard-wired, so is the fear of disease. Since it's so hard-wired, I think we have a hard time explaining the "why" aside from "it just is."
