Ellenpoly...I am 87.0237% sure that there is 'some' relationship between being overweight and our hobbies/avocations. If one geneticly tends toward fat, it is not as likely one will take up ski jumping or rollerskating. Singing...or sewing...or painting is much easier to do.

This is obviously not a hard & fast rule, but it can affect what you have noticed, a 'tendency' for folkies to be above average in weight. Add to that our fondness for beer and conviviality, and you get a trend. I know a number of Mudcatters who ARE thin, but many who are not, and not all of them can easily control it.
