Going outside on a bright, sunny day? Don't forget your STD block.

The long sunny days of summer may increase the risk of catching a common sexually transmitted infection. And it's not just because people have more sex when the weather is nice.

Staying out of the sun may decrease your risk for HPV and the cancers associated with that, as well as assorted sking cancers, but there's a trade-off:

Many studies have noted a link between cancer incidence and how far north people live. In general, these reports show that several kinds of cancer, including colon, prostate and breast, are less frequent in southern areas, suggesting that sunlight may protect against them.

Armstrong's own study, also presented Tuesday, found that the more sunlight people receive, the less likely they are to get non-Hodgkin's lymphoma. He looked at 1,398 people and found that those who got the most sun had a one-third lower risk than those who got the least.

I guess you've got to die from something.
