As an individual, I believe in people doing what they want, providing that it doesn't harm others.

Personally, I can't justify getting a tattoo because I believe the money would be better spent investing it and having it work for me.

I also refrained from getting a tattoo as a regular blood donor in Australia for many years. However, I believe the Red Cross has relaxed the rules for those with tattoos done via licenced parlours in recent years.
