I'm no genius, that's for sure. But the "what will it look like years from now" is precisely the things that come to my mind when "thinking" of getting a tattoo.
I had friend upon friend get tattoos when I was just out of high school (back then, people waited until after they finished to mutilate themselves). I'm ever so glad I remain tattoo free.
Although it doesn't take long for tattoos to start looking like crap, it would be a good idea for people to see books of naked old people with tattoos before getting their first one. That is a service the tattoo parlors would never agree to.
I always knew you were a smart guy! ;0)
