Okay, excuse me for butting in here and being a Jewish mother again, but please don't do it! My father spent his whole life having things burned off his face and body. Skin cancers caused by the sun. He said if he had known when he was young, he would have stayed away from the sun. Before he died last year, they even found a melanoma, the most serious kind of skin cancer, on his head. He went bald at a young age, and his head was exposed. Sorry to be a party pooper, but you are now forewarned.
