✔ Zombies are slow.
By definition, zombies are dead bodies. Dead bodies (if ever they rose from the dead) will be slow. It is a half-rotted piece of meat that was either wore down by a sickness and made weak and feeble or a body that has been give a deep gash (the bite that infected them). Either way the body has been beaten down and let to rot, therefore there is no reason it could move at the same speed a living human could. Yes, they can accelerate past their steady limp. But can they run? No.
✔ Zombies aren’t smart.
As said above, zombies are rotting pieces of meat. They can’t talk with each other and plan to gang up and attack certain area. They just go where they can find food. Also, the dead don’t use tools or weapons. One won’t do something as simple as picking up a rock to help them get into a store. They would much likelier charge into the door again and again till is gives way. The reason for this, as far as I can predict, is because when the person dies their whole brain shuts down but when they become reanimated, only half their brain comes back on. The half based on instincts, such as “get food.” The rest of their brain remains dead.
✔ There are only two ways to get infected.
This one actually took be a bit of time to consider, but this is what I think: the two ways of getting infected are getting bit or getting the original fever that leads to zombification. I’ve heard of other ways that seem likely as well though, for example, rubbing an open wound again a zombie. But if you were close enough to rub against a zombie, don’t you think it would be more likely that it could bite you rather than just go on?
✔ Zombies eat any kind of living meat.
I’ve heard many times that zombies eat just the flesh from humans. I don’t think so. As stated above, zombies aren’t smart, they just want to eat. Why would they distinguish a human from a deer? Meat is meat. They would eat either one. With that being said, I believe zombie will only eat living meat. Meaning if they’re limping through the forest and find a dead deer, they won’t eat. If they did eat meat that was no living, what would be stopping them from eating each other?
✔ They have no memory of their past lives.
In the newest version of Dawn of the Dead one of the characters suggests all the dead are flocking to the mall because they might remember it from their living life. I don’t think this is true. How could they remember it? The part of their brain that truly thinks is dead. Its also been said that zombies stop attacking a loved one after realizing who it was. Like I said before, there is no way for them to remember that. All their memories are gone and there is no point in trying to remind one of the dead who you are if they are attacking. They won’t remember.
✔ There is only one way to kill a zombie.
This is, as far as I know, agreed to by most. The one way to kill a zombie is to destroy the brain. Shoot it in the head and it stays dead. You could also cut off its head, which would kill it as well, but other than this, nothing else works. You can shoot it in the chest, it will get back up and come at you again. Zombies don’t feel pain, nothing else will even phase them.
