Why do we aim for the head?

Aiming for the head is a notoriously difficult thing to do, you may be a whiz in video games, but firing a weapon in real life is quite a bit more difficult than video games make it out to be. There's a reason why police officers and soldiers are taught to aim for center mass, instead of those sweet headshots, and that's because center mass is far easier to hit, and will seriously ruin a "zombie's" day. and considering limited ammunition, it's better to be safe than sorry. Now a "zombie" might not have vital organs functioning anymore, and it cant bleed out, but they do still have to obey the laws of physics, and if you manage to destroy a vertebra, or blow out a kneecap, that "zombie" isn't walking anywhere. Our skeletal system might be easy to overlook, it's on our inside and literally just sits there your entire life doing a whole lot of nothing, but one of the things it does do is provide structural support for our muscles, but without it, we'd all basically be fleshy bean bags. For "zombies", destroying that support is going to drop them faster than Taylor Swift drops number one hits about ex-boyfriends, and while that might not be a killing blow, that doesn't really matter if the "zombie" can move around anymore.

Just saying
