I often embarrass my daughter when she has some new friend over. If the topic comes up, I give a demonstration. I'm 62 and I've never tried to get a tan and work indoors, and I haven't had a serious sunburn in close to 40 years. On the other hand, I lived spent the last 20 years in Austin, TX. I mow the yard and I ride a bike and in the summer months I put on sunblock before doing the bike rides an sometimes mowing.

The exposed parts of my arms look like I'm 62 -- freckles, some age spots, the skin has lost a lot of elasticity. But then I roll up my T-shirt sleeve to expose my shoulder and my skin is like it was when I was 25: not just pale, but no freckles, no age spots, still supple.

the culprit is not the sun-- but overdoing it. If you overdrink water, it is fatal, too.

The sun is responsible for benefiting over 200 processes in the body. And you don't need to be out in the sun all day to get the benefits (if your job does not demand it).
