From what I've read, sunshine really is essential for health. Getting sunburned is bad, even a little bit. There's also been research (no, I don't have any footnotes handy, you'll have to look it up) that people who don't get enough sunlight have a greater instance of MS. And there's been research (which I'm sure is being refuted as we speak) that sunblock may not be very good for us, either. Sigh! I guess we'll have to use restraint and common sense? Ha!
