I personally don't like tattoos so I don't have them, but many people enjoy how they look. I do wonder if they will regret something in the future. I see teenage females for example with remarkably childish and silly tats on their legs, they like them now but in the future?
There should be enforced laws that minors are not allowed to be tattooed in any circumstance. When you see a 15-16 person with tats I do feel angry.
I did post a few years back (I think) of interviewing a young man for a job. He had love and hate tats on his knuckles and swastikas on his forearms, and neck. He seemed pleasant but his tats displayed an attitude that I was uncomfortable with, particularly since the job involved working with female staff, and without being sexist, I was concerned that his attitude would not be right.
As Tekla pointed out it is a fad. I think maybe coming out of cable shows such as LA Ink etc. While I appreciate the artwork involved, and the pain tolerance

the person has, the large 'arty' tattoos are probably unable to be removed by any laser technology currently available, so if someone wants them removed they would be looking at skin grafts, and big ones at that.
But people do weird stuff without thinking through the consequences.
