Zombies in general don't make much sense as an enemy because they're basically just humans with a little less. Let's face it, even ignoring bleeding out and organ damage, humans are not exactly the hardiest creatures. We're the Glass Cannons of the Animal Kingdom. If you break a zombie's pelvis, it's not going to keep shambling at you, it's going to collapse and have to drag itself by its arms, because its legs won't work properly. Assuming a zombie still uses the central nervous system to send signals from brain to body, which is not a farfetched assumption considering the brain is the only necessary component of the zombie, if you sever the spinal cord in the upper chest, the zombie is basically going to be rendered entirely useless. That's not to mention the fact that, if they go at 100% of human capacity at all times, their muscles, connective tissues and bones are going to be rendered useless in a very short time, because they aren't designed to withstand those kinds of forces for extended periods of time. If the zombie was still capable of healing, it would be a different story, because the body would get used to it, but they can't, so they will always end up useless before too long.
Yes, I do spend too much time thinking about zombies, why do you ask.
My personal RAGE for today was that I finally got fed up with getting called randomly by some stupid college in Pittsburgh. So fed up that I looked up their phone number so that I would know who exactly was calling me, because I didn't know before, because for some UNKNOWN REASON, apparently people at this particular college had never really grasped the concept of LEAVING A FUCKING MESSAGE. FOR FUCKS SAKE! THEY CALL ME TEN TIMES A WEEK FOR THE PAST MONTH AND A HALF AND NOT ONCE DO THEY LEAVE A FUCKING MESSAGE. THEY CALLED ME TEN TIMES IN ONE DAY AND STILL FAILED TO LEAVE A MESSAGE. Next time they call, I'm going to ascend to a whole new plane of rage and anger. Watch Colorado, because in the next week or so, it's going to be flattened by my atomic F-bombs.
