On any number of shows, the main characters can take terrible blows to head---hard enough to knock them unconscious for several minutes to possibly even hours---and yet they can stand up and "walk it off," without any debilitating after-effects, physical disfigurement or death. For example, the boys on Supernatural have taken guns, 2 x 4s and even iron crowbars to the head, without any lasting effects or even scars, when they really should be dead or in a vegetative state by now. The sheer number of concussions that they've suffered would leave any human severely disabled or even dead.
Another thing that's always bothered me is that, when people get shot in the television world, they almost always get shot in the shoulder. From Bonanza to Magnum, , to Sliders, to Person of Interest. It doesn't matter where the bad guy is aiming; the hero always takes it in the shoulder and is completely recovered by the next episode. It's like the bullets can only enter the body through the shoulder.
