I read a pretty convincing piece that tattoos compromise your immune system.
First of all, a couple of colors of ink used in the USA are banned in Europe as probable carcinogens.
More important than that, the ink lodges in your lymph nodes which are major immune system components. When full of ink, the notes turn black, become hard as a rock, and no longer work as the filters, which is their primary function.
I'm glad I never got a tattoo.
Personally, I don't really find them attractive anyway. But to each his/her own.
