Zombies, according to Max Brooks, are humans infected by the virus solanum, which slowly "kills" the person, disableing their body, and bodily functions, excluding the brain. Zombies are not super strong, they can only be as strong as the person they were whilst "alive", so they can run, and due to the fact that they are never worn out, nor do the become tired (redundant?) they can run much longer and further then humans. The only way to kill a zombie is to destroy its brain, if you simply chop its head off, it is still a threat. To dispose of a zombie you should use fire. People who have been dead for a short, or long time before the virus was spread, will not be popping out of the ground, why you ask, its simply because of the long process that is the burial system which takes 1-4 weeks. Zombies can how ever smell things up to 1 mile away (give or take the breeze). Zombies will very very slowly decompose, this is due to the fact of the virus inhabiting the body, orginisms are repelled by the zombies' body. And should the day come that a zombie attack happens, it is strongly suggested that you DON'T go and try to kill as many zombies as possible, just find a building that can wilstand zombies, and has plenty of supplies. Just remember there is no safe only safer. BTW The Zombie Survival Guide is my bible.<-- solanum zombie, Voodoo zombies differ GREATLY
