Seriously you would just die if your limb was trapped in rocks in a desert like happened to that guy? You wouldn't cut off your hand to be free? WHY NOT? It saved his life. Plus the hand was obviously dead anyway.
As to pets, it would take starvation first but sure. People have done this, people trudging through the arctic have eaten their sled dogs. Do you have any children? Would you let them die before you fed them your cat?
And squirrels are no more yuck than delicious chicken.
Yup. I think I would just die. Would you jump in shark infested waters on the chance that you might make it to land, rather than stay on the boat and wait for help? There are some things we as individuals just won't do. I think this is one of them for me.
As for feeding my cat to my daughter, that's a tough one. I might as well feed my wife to them, if that's the case. At what point do you say enough?
