Well, I was thinking. If zombies are reanimated bodies that have the brains functions, would that mean that it would remember your lifes skills? For example, they say you never forget how to ride a bike once you've learned. Its all basic muscle memory. So if you knew how to do parkour very well while alive, wouldn't that mean your zombie form would also know how to do such activities? Even if it is going off of muscle memory. If you were a leader, maybe your zombie self would organize the lesser zombies to do your bidding. That sort of deal. That certainly would make for an interesting zombie film to say the least.
