I don't understand reasons to create such topics. Are you preparing for apocalypse?
We know that in extreme situations people acting by their insticts. I can't imagine what would need to happen that I would eat my mother. As one person already said, I'll better die myself than eat my mother. And I can't understand people who are saying that they would women, who gave him birth.
I also do not understand what the purpose of this topic ?? This topic is very disgusting, disturbing thoughts. Perhaps indeed if in a state of urgency, in a state in order to survive, humanity will use instinct, and I'm sure the human animal will not get to eat their own mothers. Mother is the one who most love us, the most valuable. Would not be able to eat it. I prefer to die rather than eat my mother, and this is not bullshit.
