here's a scenario: you were sailing on the ocean, and your boat sank. You and a friend managed to swim to an island, but rather than a tropical paradise, it's just a big rock, bare of all life. there aren't even any crabs or little shell creatures stuck to the rocks. and it's really cold! oh no!
you don't have any fishing equipment or a satellite phone, and it's unlikely you'll be found for at least a few weeks.
all you have is some wet, already moudly bread, and its only enough to last for one person. and a couple of dead bodies of people what drowned hae washed up.
will you eat the bread, which is mouldy and might make you sick and kill you, knowing that you'll probably still die of starvation if you dont eat some person later?
will you eat the bread, and then not eat any human flesh and hope to survive?
will you just eat the people?
will you eat nothing and just hope you get rescued in time?
