Eating humans IS wrong. The meat is stringy and tough!
Also, my brother-in-law says that if you ate a person, “you would digest human fat which usually only happens when you are starving and digesting your OWN fat. So, your body thinks you are starving, which makes you more ravenous for MORE human meat!”
I haven’t read Allan C. Hutchinson's book Is Eating People Wrong?, but I think the title refers to the Case of the Speluncean Explorers. Read all about it! (And thanks to Eavan Shaw and Andrew Simon for the assists.)
