Finally, the zombie bite – the worst kind, for the victim will get infected and become undead. Zombies do more damage to the skin than you might think because they don’t feel pain. They won’t care about how hard they bite or indulge any hang-ups about damaging their teeth. As it is, the human jaw can generate 180 psi. We’re capable of tearing flesh and biting off the nose/ear of other people. Zombies exert twice as much force, and if they’ve been reanimated for a long time, the teeth may be jagged and sharp. Note the damage in figures D and E.
