Saturday's Daily Star says that the Chilean miners thought they might end up eating each other to survive.
Some people think that's disgusting but they would've been underground for a long while. They'd be like veal.
It's amazing what you'd eat if your life depended on it. It's very easy to sit with our bellies full and say it's wrong but we don't know how bad things would've been. After weeks of starving you'd be willing to eat the meat of another human. After a few more weeks you'd eat the offal. And after a few weeks more you'd finally give in and finish up the Pot Noodle you took down there with you.
