The thought of Human cannibalism blows my mind. I mean Why!
It's horrible how people can eat flesh and internal organs of other people.
I'd imagine out side if physo's in the 1st world. Much of the world has plants and animals they can eat instead. 
That's right but I wonder if it's true, maybe it's just another myth, like vampire folklore myth, there has been many like in Hebrew culture or ancient Greece.
I've seen documentaries on it. It seems to happen less and less now days.
Topics like that are very popular in literature as well, for example vampire literature covers vampire subject and has been very trendy lately.
Like the Ann Rice Vampire books?
For example, or Dracula written by Bram Stoker in 1897.
O a classic. 
There have been over 200 films featuring the character of Dracula.
