Some will say that when there is no more room in hell..the dead will walk the earth. So...if it´s true...the dead will only prey on human flesh....lossing the animals and other stuff. This is the end of times?
well, if the dead ever do come back and start attacking human's I would think of them like other predator animals, they all have their own appetite of something else right? well a zombie's appetite is for human flesh. mostly because its how they are. like Lions or sharks.
except the zombie's method of reproduction is eating a living human.
I don't know why zombies are out there, but I have a theory on why they eat humans. I think it's a parasiticle type mind. I kind of think of them like a misqito. Ever wonder why your dog gets heart worms and your cat doesn't? It's because you're horrible pet owner. But also because the misqito (am I spelling that right at all?, I don't think I am.. I'm retarded...) goes after the larger heat and carbon dioxcide source. ( I watched a shit-load of Discovery..) Maybe zombies are the same way. And ever notice when the groups of survivors start to then out, and the food source gets more dwindled for the zombie, they tend to move slower and have more advanced states of decomposition? Maybe it's because the human provides some nutriant that they need and is only found is humans. I don't know, could be pissing in the wind on this one....
