Study: There's no chance anyone will survive a zombie apocalypse

Contrary to what dystopian pop culture may tell you, we probably won't survive any kind of zombie attack.

According to a study recently published by students at the University of Leicester in the U.K., we'd all be dead within a hundred days of the rise of the undead.

Students used a basic model often used by epidemiologists to track how quickly diseases spread.

Assuming a single zombie spurs the outbreak on Day One, and assuming each zombie has a 90 percent chance of infecting one new victim per day, it would only take 20 days for the infection to become widespread.

By the 100th day of the apocalypse, only 181 people on earth will still be alive.

Even if you assume it would take longer for the infection to spread in distant parts of the globe, there would only be 273 survivors after 100 days.

If you're a "Walking Dead" zombie fanatic and you think you're prepared to fight back by destroying the brains of your attackers, expertly avoiding bites and reproducing -- there is a small chance you can outlast the apocalypse.

According to the model, zombies who have a lifespan of one year -- which is higher than the 20 days assumed in the original model -- it would take a little over 3 years to wipe out all of the undead. After 27 years, humans would begin to replenish the population again.

Of course, who knows if this type of zombie will even be the kind to attack us?

If the zombie apocalypse looks more like "28 Days Later" an infection can spread through blood or bite.

But if it looks like George A. Romero's original "Dead" trilogy, zombies will spring from people who die of any cause, thus making it much harder for anyone to stay alive (and undead.)

Regardless of what model you choose and how experienced you are in zombie survival, it's best to prepare yourself for the worst possible outcome in the event of a zombie outbreak.
