I think the OP is onto something, he just phrased it wrong.

It's my own personal theory that attractive people tend to have better natural scents. This is not to say that there are people who don't have BO or that some people don't need to wash, nor is it to say that all "good-looking" people smell good and all "unattractive" people smell bad, but it's pretty plain to see that every person smells differently naturally (you can call it pheromones, whatever). I think there is a notable positive correlation between physical attractiveness and the pleasantness of one's odor, although I could be wrong...
