Cutting has become part of the "bad things are cool" fad. If people don't want you to do it then you should do it often. I have a few friends who have done it but they don't do it as often. Why? Because it doesn't help. Its no longer about getting attention anymore. Its more about doing something that people don't want you too. Its like taking drugs or drinking too much. I can also see why it started though. Sometimes you get stuck in this boring routine and life becomes so dull you just wish something would happen to stop all of it. So they cut themselves in order to cause a raise of emotions. The rush of coming close to death is what they want. Dangerous sports don't have the same rush as dying slowly in a pool of your own blood alone. But cutters today think its cool to have tracks all over their arms and legs and show it off to friends like a new haircut. Once something more dangerous appears it will die down.
