 The dude who has the most tattoos, I guarantee you almost always has the highest anxiety. It's very quarreling, so you get tattoos to look tougher, because who's actually more concerned about looking tougher. Somebody who truly is tough, or somebody who has high anxiety and thinks about being attacked. So if you go into deep psychology, it makes sense that people put on an outward show of how scary they are, or actually less scary.
