Ok. SO I go to the beach today--I put on sunscreen, I am only there for an hour...I come home and voila, sunburned shoulders. But then I realize, wait! this sunburn pattern doesn't match the shirt I was wearing on the beach! I think for a moment. I was out running for an hour this morning with no sunscreen on, and the tank top I was wearing then remarkably matches...
so: sunburn tip number 63: beware the sun while exercising. number 64: remember that sunburn doesn't always develop immediately but can in fact take a few hours to show up.

So apparently my theory that if I'm moving the sun can't burn me is false. shucks.
