It’s surprisingly difficult to not eat a little human flesh. People nibble on loose skin and the insides of thier mouth a little, you end up swallowing blood, and there is often a tiny bit of human biomass in processed food.

Ergo the “significant” qualifier. Imagine the sense of defeat to fail in your New Year’s resolution to not resort to cannibalism by years end… so you have to be careful how you define your test case.

If I were a cannibal, it would have been an ambitious resolution, but the whole point was success through low expectations.

But fair enough, people tend to be touchy about people eating people, and rightly so. No way that ends well as a mainstream practice.
