30% chance of SURVIVAL?! *Ahem*
You've obviously forgotten to take many things into consideration. There are first, many types of zombies. There's viral infection zombies, undead zombies, and finally, medical accident zombies. Each with their own sense of speed, smell, and sense.
Viral-infection zombies are usually vigorous and fast, with accute senses, due to the fact that they combine the savage nature of a beast with the strength and power of a living human being. Since most viral zombies kick in within SECONDS of the person being desceased/taken over by the virus, the full physical functions of the human still exist. That's why they're so speedy. Viral zombies care more about spreading the infection, rather than the brains themselves.
Undead zombies are the slow ones. Most have been dead for quite some time, and have suffered a large amount of brain-rot. It's difficult for them to put one foot in front of the other, making them stumbling, blundery slow-pokes. They have more of a desire for brains, since they themselves, lack brain juices. But their forces are more supernatural, making them a force to be reckoned with, because they'll stop at nothing to satisfy their cravings. Even if it takes all day.
Medical accident zombies are the least "zombie like", but they still count. Such zombies are featured in the novel/film "I Am Legend". They count as zombies because they can spread their "disease", like the viral zombie, and cause a complete change within a fully functioning human being. These are the creatures more related to "wolf-like behavior" as mentioned in the quiz. They are adaptive, they are organized, and they are very, very angry.
So yeah. Take this quiz and SSSssSS-S-SHOVE IT. I may be obsessed, and I may not have a life, but I ain't effin' dumb. Come back when you've taken this description into consideration, ya turkey.
