The Zombie, a creature so common to film and culture yet so diverse and distinct in their respective adaptations that it's hard to find a single set definition. For the first time in zombiology there will be a written work that definitively describes the disposition of a realistic undead organism. This will be my first article on the subject so please go easy on me and if you feel i have missed anything of importance tell me.

First let us consider where a zombie comes from:

Evolution Zombie Vs. Infection Zombie
The two major schools of thought on the origin of zombies are: 1) Zombies evolved from humans much as humans did from apes or 2) zombies are borne of a natural or man-made virus. Though evolution would explain how zombies sporadically appear in Romero Zombie movies this can be ruled out because a majority of zombies cases were reported during the 1900's which would mean that their evolution happened practically overnight. This leaves natural and man-made viruses; a natural virus would be unlikely because as stated earlier, most outbreaks were in the 20th century and we would have found it in the wild by now. This leaves the man-made virus which would make sense because most infection occurred when medicine as a science was formed (IE, 1900's). The virus could be accidentally created while experimenting on test subjects like monkeys or the virus could be made intentionally for some unknown reason.

Slow Zombie Vs. Fast Zombie
First off let it be known that zombies are not dead, it just seems like that because the victim shuts down into what seems to be a coma-like state while the brain is being infected (explained later). Because the zombie is still alive, there would be no reason for it to move slowly. On the other hand though the zombie could not run faster than their former self, albeit they will be able to run longer because the brain will not be operating like it would on a human and thusly the zombie would not feel fatigue. This does not mean that the zombie will be able to run forever because eventually a combination of lactic acid and ATG usage would make it collapse.

This article is far from finished but I'm taking a break, it should be finished by Halloween though, feel free to comment in the mean time.

I can simply tell you now. Zombies have great sense of smelling and hearing they just have very unbelievably terrible eye sight. So if your going to travel do it in the day so you can see them remember there eye sight sucks due to retinal and tissue damage. Other then that carry a crow bar or hatchet on you at times and have fun with the free for all no consequence murder fest.

Real Skin Jobs; Considerations And Issues.
However unlikely, a condition similar to a skin job outbreak is NOT totally implausible; Indeed, with terrorists trying to develop such delightful toys as biological and nuclear/radioactive weaps, and considering that these people ARE quite innovative (they are not stupid; over half of al Qaeda’s top 10% staff, equivalent to the Commandants of the Marine Corps and Coast Guard and Secretaries of the Army, Air Force, and Navy and their immediate staff, have doctorates in various fields; many lower level leaders have various degrees, to roughly 50% of the overall organization), we should turn a wary eye to what ‘could’ be.
And it’s a good way to scare your co-workers into thinking you’re REALLY off kilter.
