It seems that people in the US get skin cancer on the left side of their face and body more than the right side. Researchers think that may have to do with the way we drive. The windshield and windows of your car block most of the UV rays but if you drive with the window down you are letting in more of the dangerous rays. I guess the best way to see if this theory is accurate is to go to Britain and check to see if their drivers have a lot more skin cancer issues on the right side of their face and body because their steering wheel is on the right side. Any British dermatologists out there have an opinion on this?
