Think about all those teenagers in their dark rooms, glued to their PC's, turning every life problem into ridiculous melodrama. Why do they make those cuts on their arms? It's because making the pain-and subsequent healing-tangible releases endorphins they don't get otherwise. It's pain, but at least it's real. That form of stress relief via mild discomfort used to be part of our daily lives, via our routine of hunting gazelles and gathering berries and climbing rocks and fighting bears. No more. This is why office jobs make so many of us miserable; we don't get any physical, tangible result from our work. But do construction out in the hot sun for two months, and for the rest of your life you can drive past a certain house and say, "Holy ****, I built that." Maybe that's why mass shootings are more common in offices than construction sites.
