Yeah, I've heard before that cannibals commit such practices as drinking blood and eating hearts as a way of gaining spiritual benefits and the likes. Makes sense to me. The spirit is within the blood. Your correct on your points. :)
Those who don't understand will inevitably call me crazy. (not pointing fingers at anyone here) However, it makes sense when you believe that Man has a spirit. It was their way of gaining power.
I don't know who was the first to come out and yell "Zombie's lol!" but the topics don't really have anything to do with such, though I kind of want it to happen.
note to self: (Man, Agent can talk and talk and talk! lol! (no offence my friend) )
