Tobacco has been getting lots of attention recently, none of it good. Smoking has now been found to accelerate cognitive decline in aging.
We know smoking is bad for us, and we all also know that too much sun can cause skin cancer. Previously, it was thought that the cancer-culprit here was UVB rays. The National Academies of Sciences has published a paper contradicts that view, and indicates that UVA also causes DNA damage, and thus cancer.
So, take your vitamin D. Another recent study indicates that vitamin D may have potent anti-cancer activities....but don't think this means you can just go sunbathing!
