I saw a video of a guy who tried to shoot himself with a shotgun. Aimed it up into his chin and blew his whole face off, no nose, mouth, eyes were almost out but he was definitely blind by that point. Didn't touch his brain at all and he was still conscious and moaning and screaming in pain. Could see his breath coming out of where his windpipe would've been connected to his mouth. Now I'm pretty desensitised to these types of videos but that one stuck in my mind. He survived the whole thing, and had surgery to close up where his face would've been, only had a small hole with a tube where his mouth would've been.
