Zombies Cannot Exist. Period.
Legends of centuries past illustrate zombies as awakened human corpses controlled by witchcraft or voodoo, but today’s Hollywood zombies often are created by some sort of infectious virus. And for some great cinematic effect, the zombie plotline rides on contagion through zombie bites. Tyson commented on how some diseases, like rabies, can be passed through bites, but symptoms don’t develop instantly. As he said, “ When something bites you, you don’t turn into that thing. If that were remotely possible, Evander Holyfield would have turned into Mike Tyson long ago .”
