What the farg causes humans to turn into slobbering and brainless ZOMBIES that hunger for brains?
Over the years, studies involving the causes of zombie invasions have formulated a few theories.
The "VIRUS" Theory
George A. Rom. is a staunch believer of this theory. Basically, a virus is loosed upon the world; resulting in all the dead coming to life. As long as you die, you become a zombie. This is rather bleak.
Did you know that...
1) 39892642 people die a second?
What the farg are we gonna do with more and more dead people running around on the streets? Also, the birth rate will go down tremendously because people are less likely to have intercourse with zombies battering on their barricades with their fists. Less and less people will be alive to fight the zombies, and sooner or later, the world will be overtaken.
The "I-bit-you-and-now-you're-screwed" Theory
Basically, this theory states that as long as you do not get bitten, you remain as a human. Thus, the nature of this theory is highly suggestive of the entire zombie invasion stemming from a single "Host" that spreads the entire zombie plague through the biting and infecting of others. While this theory is less bleak as dead bodies do not turn into zombies, its still pretty screwy, especially when someone you know gets bitten and is in the process of being transmogrified into a zombie.
Many sub theories have stemmed from these 2 main theories. Most zombie movies have left the trigger to the event unknown, making it purposefully vague with intent to intrigue.
While both situations precipitate into a take-over of the world (by zombies), it is still possible to fight off a zombie invasion if we stay prepared and vigilant.
On that note, I am signing off.
