It's the question that everyone is dying to know the answer to; how long would the human race survive if there was in fact a real zombie apocalypse? Well, according to scientists the news isn't great.
We're not exactly sure what criteria was used in determining the results of this study, but by all accounts it appears that the human race would die-out completely within a year of a viral zombie outbreak. Just 100 days after the start of the outbreak there would only be roughly 273 humans left alive on the face of the entire planet.
Zombies would end up outnumbering humans by roughly 1 million to 1, not great odds for the propagation of humankind. Because we have condensed mass numbers of our population into a number of small city centers, the virus would spread like an uncontrolled wildfire, consuming the population far too quickly for us to medically defend against it.
Not to worry though, not all hope is lost...
