I'll provide a little counter-balance to this thread by posting this link!!
Of course, I don't think going out and baking and getting burnt are healthy, but I try to limit the damage other ways-----wear a hat, limit time in the sun, wear a shirt, etc. As we hear of this causing cancer and that causing cancer, it's hard to look at a long list of long chemical names on sunscreen without a red flag waving in my mind!!
I won't say I NEVER wear it, but it's seldom, and only when I'm going to be in a lot of sun for a long time. A physical block is still the best-----hat, shirt, etc.
