I noticed this with a lot of medical students. Sun, BAD! Skin protection, GOOD! It made no sense. I understand going out 8 hours a day will literally BURN you, so just use common sense, when your skin starts turning red, go into the shade. Simple. I've been able to swim fine for 2 hours on a hot sunny day and no sunblock. But past that I burn and I never want to experience getting sunburn again.
