We are a product of the values and opinions of our parents and the society we grew up in. At that time, tattoos were unacceptable, and that is what we grew up believing. It is an emotional argument, and cannot be refuted.
I got my first tattoo when I was in my late 40s. A few years later, I got another. I stopped at that point, because I am very selective about what I get, seeing that it will be with me forever. The two I have, I'm happy with.
By the way, as you may have guessed, getting tattoos in your late 40s/early 50s is not a sign of rebellion. It is a sign that I've reached the stage of my life where other people's opinions (outside of close friends and family) are meaningless to me. I believe what I want, you decide for yourself. Don't impose your beliefs or criticisms of my beliefs on me, and I will extend the same courtesy to you.
This belief system has done me well, and applies to everything except Ohio State Buckeyes Football. All must acknowledge The Mighty Bucks! ;D ;D
