Oh, I see so the virgins that were killed and had their heart eaten were 'organ donars' and by this sacrifice they kept their populations at a stable level? Well, my! How progressive of them - clearly they were ahead of themselves. Wait.. Didn't the Myans disappear all on their own.. Didn't they eat themselves out of house and home and archaeologist think their societies collapsed because of catastrophic environemental destruction?
Odd.. Clearly they must not have been sacrificing enough virgins!
