happens to the body and brain after being deprived of food for so long. Basically your body eats up all your fat first, then it starts eating up your muscle, then it starts eating away at all your non-vital organs, and then it somehow starts eating away at the all of the parts of your brain except for the part that controls your natural survival instincts (or something like that). They said that most people only consider cannibalism at that point.

If it were me and a fat obnoxious guy were on the boat, I'd kill him myself and start eating.
