True enough. But sunburn still hurts, and can lead to interesting problems not the least of which is malignant melanoma. Reduces the likelyhood of one form of cancer for an other. Lets face it, odds are whichever comedian that claimed "everything will give you cancer" was right.

I would say that the lack of vitamin D has less to do with sunblock usage and the fact that we've turned into a culture of troglodytes. The glow-in-the-dark white look is too common becuase most people spend way too much time inside. And not getting enough fiber.
