Human flesh is said to taste like very rich pork.
Just don't eat the brain. Doing so can cause a degenerative neurological disease called kuru.
There is a tribe of Amazonian Indians who, instead of burying their dead, cremate them. After the cremation, they mix the ashes into a special kind of soup, and during a very solemn ceremony, the mourning relatives drink the soup and ingest the ashes.
When asked why the do that instead of burying their dead, they found the question to be appalling.
"Bury our dead?! Why would we let the bodies of our people rot in the dank, cold ground, when we can give them a warm home in the bodies of those who love them the most?"
An interesting perspective, isn't it?
