Should you be stocking up on brains to feed the undead that will rise on Halloween night? Well, not quite. But according to this highly scientific whiteboard drawing, a zombie apocalypse is technically possible.
No, you won't see rotten corpse hands clawing their way out of graves, but it is possible that an incurable illness could kickstart a zombie apocalypse. But we already know this from The Walking Dead.
The video above, written and created by Mitchell Moffit and Gregory Brown of AsapSCIENCE, illustrates how a zombie virus could infect parts of the human brain and control our thoughts and actions. It's all bad news. But it's set to a friendly soundtrack, so we don't feel too threatened.
According to the video, "The main factor involved is finding a virus specific to the brain areas for these symptoms, while leaving the other areas in tact."
And here's the kicker -- the perfect zombie virus will enter through your nose. So stop smelling stuff now, or we may have a crisis on our hands come November.
