I rarely sunburn and can count the number of times on one hand. However, three days ago, I spent about three hours at the pool. I covered myself in
sunscreen prior to going and while there. When I came back, it appeared I had a nice tan. Then, as the hours passed, my back and the back of my legs became very red. Since I was in the sun, I spent even time on both sides of my body so as to get an even tan, but for some reason only my back side burned.
