Kinda a trick question with in a few days your system begins to eat itself so you kinda eat yourself even if you say you will starve. Personally if there were other in the party cannibalism sounds interesting if you had to do it.
would you rather Get stuck in the rain or in the middle of nowhere.
Would you rather adopt a dog that's the cutest thing in the world, but is 7 ft tall when standing or a dog with no hair, teeth or tail, and no paws, just little nubs?
