Some recent research found that growing up in college towns was strongly correlated with becoming famous (as in rating a Wikipedia entry). (Urban areas and immigrants were also correlated.)
That was on my mind when I saw this map.
Why? Because I know where Tompkins county, NY is, which is where Ithaca, NY is. It stands out on the map of smoking rates by county--the dark blue dot in upstate NY, meaning it has one of the lowest smoking rates in the country. (I suspect the other dark blue areas are also college towns or rich urban areas (Charlottesville, VA is one guess.)
Now I don't know there's a correlation between becoming famous and not smoking, but inquiring minds want to know. (Particularly as I started to smoke in Ithaca, NY and am not famous.)
