No. 5: Salt Lake City, Utah Is it the most vain or the most good-looking? You decide. We hesitate to put "plastic surgery" and "attractive" in the same sentence, but if you're from the camp that believes there's a correlation between the two, Utah's largest city ranks for having lots of plastic or reconstructive surgeons — six for every 100,000 people. It also beat Denver as the fittest city in the U.S. ... so if anything, the people there seem to spend lots of time trying to look good.
