What Happens to Zombies that Don't Eat?
I assume zombies don't have blood flow, since they can't be stopped with a shot in the heart.
If so, how is it possible they can maintain their strength by eating? The proteins of the fresh meat requires a blood flow to be extracted in the bowels, right?
Or is it generally understood that zombies only eat out of habit and eventually lose strength and rot with less and less movement and danger for the still living as a result?
