Annoying thing I learned from this movie....
1. When attempting to amputate someones arm with an axe, don't be prepared in any way. Do not fashion a tourniquet that works, and don't prepare any method of cauterising the stump. Dabbing a towel on the arm will stop the bleeding and raising the stump above your head will be enough to stop blood loss. Also, morphine (or any drug) is injected simply by stabbing the needle into the arm in a random fashion - don't be bothered by such trivialities as ensuring you are in a vein by drawing back on the syringe!
2. When confronted by an obviously contagious disease, ensure you spend as much time around the bodies/infected as possible. Touching them a great deal helps, as does repeatedly entering a sealed off area to fetch unnecessary crap.
anyone else?
