Tim Verstynen and Bradley Voytek of the Zombie Research Society have narrated a short, animated video outlining possible medical explanations for why zombies are zombies. You might think this is silly, because zombies are fictional... until you see some wobbly humanoid lurking in your backyard, eating a squirrel. I just want you to have the information you might desperately need.
