   I've always found the subject of cannibalism fascinating.  Most people don't realize how often it show s up in history.  All of the continents but Antarctica have some incident of it reported.
   In Asia they sacrificed to the Goddess Kali, a goddess with a craving for blood.  In the nineteenth century, in Calcutta, they sacrificed a child everyday in a certain temple.  In fact, if a couple wanted a lot of children, but only had one they might sacrifice their only child in order to get many more from Kali.
   In Central America the Aztecs were famous for sacrificing people, and then eating the corpses.  The conquistadors put a stop to this when small pox killed off most of the population.
