The whole tat craze is for the weak minded and "me too" crowd. When people hit 50 they are going to wonder what the hell they were thinking.
If you want to make some cheese, develope a topical product that will remove tattoo's that is 100% safe and effective. There are going to be 10's of MILLIONS of idiots walking around when they get up in age a little ashamed of the dumb ink they got put on them.
