Halloween has come and gone, but thanks to AMC's new horror drama, "The Walking Dead," people will have zombies on the brain long after the costumes and candy are put away.

Created for TV by Frank Darabont ("The Shawshank Redemption" and "Green Mile"), the series revolves around a post-apocalyptic world infested with the living dead. Reviews have been almost unanimously positive — and with the Oct. 31 premiere snagging 5.3 million viewers, (The most-watched premiere episode of any AMC television series) zombie-fever is gripping the U.S. — and without all the death and destruction.

But I wonder, could the world survive something like the world we're addicted to on TV? According to some researchers in Canada, that answer is probably no. Forget climate change, the walking dead would extinguish the flame of humanity in a matter of months.

The mathematical exercise, conducted by the University of Ottawa and Carleton University, studied a zombie vs. humanity battle, with the researchers choosing "slow-moving" living dead similar to AMC's series.

They concluded that humanity's only hope was to "hit them [the undead] hard and hit them often." They added: "It's imperative that zombies are dealt with quickly or else ... we are all in a great deal of trouble."

The easiest method of dispatching the undead? Decapitation. Unfortunately, the researchers noted that there would be thousands more coming after you in the meantime.

So, while a zombie-pocalypse probably isn't coming anytime soon, you should be prepared for the worst. Thankfully, AssociatedContent has created a How To Kill A Zombie tip sheet, with such helpful advice like "Crow bar to the skull" and "Drop an Egyptian obelisk on them".

You can thank me later.
