@Atom Blitzer,
look , 1st off , thats not a zombie thats a parasite
zombies are not parasites
it can be a disease thats causes it i just want to say this one more time , a zombie is not a parasite , being controlled by another species is not what a zombie is
a zombie comes in 3 types
disease- they become infected either government testing or by contact with blood
disease is probable - mad cow disease has 3 or 4 cousins that have similar effects- incubation of the disease for 1 month to six , and the results are cannibalism , extreme rage and so on ...
magic- shaman raise them with black magic - till u see it noones gonna believe it
in haiti they have shaman beliefs about zombies
and the media even fed into it with a couple sightings claimed
and nuclear-they become horrificly disfigured and eat human flesh for some reason im guessing evrything else is a shadow - so highly inprobable
its possible , im just not sure if those working in biochemical weapons have developed it yet ... proballly
