I am no expert on the zombie matter all all but in regards to The Walking Dead, I thinks someone needs to hold up the zombie virus to a little scientific experimentation or at least morbid curiosity. I get that this is fiction but nothing can exist eternally. these zombies don't eat out of a survival necessity. They are merely deceased organic vehicles that were once inhabited by souls. the reanimation is just of the brain stem- just pure, base id. Michonne's jawless, armless captives prove that they don't need to eat at all. Here are my questions: How long can a zombie confined to a cell in solitary confinement "live" if it is unwatered and unfed? Years?...Months?... Can they be drowned? If frozen, do they keep on ticking once thawed? Can they be poisoned? how long does the caged, decapitated head of a zombie last? Can our survivors figure out a way to wait out this virus?
