I'll be honest with you - I don't have a single tattoo on my body. It's not that I have anything against inking; I actually love tattoos and find them interesting, creative, and beautiful. The reason I don't have one (or two or thirteen) is because I am scared. Not scared of the pain or of being disappointed with the final result (although I am not thrilled about those aspects either). No, what I am scared of is outgrowing my tattoos.
The fact is that I am not the same person I was thirty years ago when I was in my late teens (and probably thought a tattoo of Mickey Mouse with a huge boner would be hilarious). I am also not the same person I was twenty years ago when I thought that The Matrix was the most awesome thing on earth and would have probably gotten a Neo tattoo saying "Guns. Lots of guns." I guess what I am saying is that I don't trust my own taste.
Anyway, here are some people with greater taste than mine.
