A zombie outbreak such as that seen in "Night of the Living Dead" inevitably leads to the collapse of civilization, unless the infection is dealt with aggressively and swiftly, according to a mathematical study by students at Carleton University in Canada. To prepare for this horrific situation, here are some important facts about zombies.
