>Average American gets as many sunlight hours as Italy or Greece, if not more
>Yet Euro tourists and people from Southern Europe are always so much more noticeably tanned than White Americans (in my experience)

This is a big part of why Americans are so fat compared to Europeans, people need to GO OUTSIDE

(this is also surprising but confirms my bias as to how I'm able to get so tanned in just a couple of years of doing things outside daily despite living in the northernmost part of the American map)
