A friend of mine has a blackish birthmark (nevus) on the back. He's been wondering what to do with it. The doctors say it isn't malignant or anything, so it won't cause a problem. However, it's somewhat big so when he's at the beach, etc. he gets a bit self-conscious.
1. leave it alone
2. cover it with a tattoo
3. get elective surgical removal
4. rub it with paint everyday
Who do you think it is...
