This is Obvious...don't get sunburn....you wont get cancer. Pretty crappy graph in the beginning. Obviously less people get cancer toward the equator, anyone guess what skin color people have that live at the equator??? Dark to black skin. less likely to burn, he said it himself during the video. I think he said "dark skinned people are going to need at least 3,4,5 times as much skin exposure as light skinned people". Kinda sounds like he trying to sell something:think:
