The sun is a villianous two-faced ball of gas. It's all like, "Hey Bud, let me shine my rays on you to get that Vitamin D so you can live and all that." Yet, at the same time it goes, "oh heads up, these rays also melt your face like Nazis in Raiders of the Lost Ark so you become an undesirable, social equivalent of eating cereal with water". Sunscreen helps.
