Tattooing is probably one of the only industries that have been around longer than the sex industry. It has had a similar amount of criticism as well, if not maybe more. Evidence of tools used for tattooing have been found dating back to 10,000-30,000 B.C.. If you have any older relatives that want to give you any grief for getting a tattoo, just remind them that somewhere back further in the family tree, probably thousands of years, one of your relatives was probably getting tattooed by the campfire.
