I don't think there is an age requirement, but I do think there is a difference between people that got tattoos when they were young and impetuous, as opposed to people who apply a mature "logic" to it. I don't trust these people with all perfect tattoos, planned space, perfect balance. There is a humble aspect to the people that were into it before it grew, and back then it wasn't about what you had. You were tattooed. That's it. Now there is a fraction of the social judgement there was 20 years ago. I think this is the same conversation that could be had about the difference between when/if you started tattooing. It was a different business back then, just like we were a different clientele in those days.
