So with the ebola outbreak, and the fact that two infected doctors will be coming to the US, a friend and I were having a chat about the end of the world. Naturally.
We were having a friendly debate about zombies and he thought that zombies had to die as humans first to then become mobile again as zombies. Die first, then become reanimate. That made no sense to me... prepare your butt for a rant.
Think about it. Dying and then suddenly become reanimate.... that isn't possible, even in a world where zombies exist. They would still have to abide by the same laws of energy and matter the rest of the world does. Between rigor mortis setting in which causes the limbs and other muscles to become stiff and unmovable, it would be impossible for the zombie to move around. A body cannot move at all once the muscles become stiff like that, and it cannot be undone by a simple disease. When the neurons stop working or the blood stops bringing in the proper proteins to keep working and firing the muscles, they stop and don't start back up. Movement only happens when blood is pumping, and your body needs fuel to keep a pumping heart, hence why zombies are flesh eaters; protein is the best source to get energy for a human body.
That is why I personally believe that if there were to be a zombie outbreak, it wouldn't be a "boom you're dead, but now you're a zombie too," it would be like a disease that slowly attacks the neuron system. The frontal lobe, which is what essentially makes us human as intelligent and moral, becomes corroded away when the disease sets in, so what's easier to catch: a jackrabbit or a fat slow human?
They are not stupid, they just become animals that have the same instincts as all other primal creatures: eat, survive, thrive, and reproduce. Humans have become lazy and weak, also they have overpopulated the world. By targeting them, there is a much greater chance of survival, better food, and the furthering of their species if you call it that.
As for the physical structure of the creatures, debating the speed and agility of them, since I am going with the slow and lethal flesh eating disease that targets the neural system above all else, I believe the zombie would be just as fast/strong/lithe/ect as the human was before infected. However, I also believe that this would decrease over time as the disease cannibalizes the host body. Going after muscles and neural tissue, the creature would soon become weak and feeble, eventually "dying" when the last of the brain tissue is eaten away.
Welp, I want to say more, but it's nearly 2:30 AM so I should hit the hay. I would love any feedback on your theories and thoughts, but keep it friendly please. This is all just hypothetical and for fun :3
