Sorry pal, disagree there. "some" will do it for a particular reason. The rest are doing it for it being "in".
The problem with tats is that unlike the haircut I had in the 70's or 80's. I could change that very quickly, along with the dress sense then. Imagine if I had the hair and clothes permanently tatooed back then. How much more stupid would I look today?
Some fads you can change, others apart from surgery are for life !!!!!!!!!!
