Piercings come out. You can just choose not to go into a field that would stick you behind a desk, though. There is always that wonderful thing about freedom of choice.
I would say that it definitely has an addictive quality for a lot of people. Not everyone will feel the same way, but, it’s not uncommon. I found it addictive.
Despite having had multiple facial piercings, as well as gauged ears, I managed to grow up to live a normal life, with a job that would definitely frown upon those things. I think when you’re young it’s best to get it out of your system, before it’s hard to get by in the world as a “respectable” adult. Not that I agree with that concept, but a lot of society still does.
