We're all nice people here and we'd never do anything illegal to obtain it
but would you--in theory--try human flesh if the opportunity were presented to you?
The people who so famously crashed in the Andes in the 70s survived on the flesh of dead passengers, and they claimed it tasted remarkably like beef.
A few primitive tribes still practice ritual cannibalism, in deepest darkest Papua New Guinea, Indonesia, and Brazil.
In these instances it's ritualistic, not an actual food source, but they have scorned the taboo against eating one's one kind.
I'm starting to see a cure for world famine here... any third-worlders too lazy or primitive to obtain sufficient sustenance, take note.
