Tattoos are just one of the many decisions we get to make as a "Free Country". You may or may not like them, but we all would fight for the right to get one if we wanted to. I like mine as I said before no regret, as mentioned by another, it's not something one should do when drinking or otherwise influenced. And as anything else permanent, one should give it much thought as to the substance and artist who is going to do the work. Otherwise it's a personal decision.
