Are Fidgeters More Skinny?

A rather interesting article has been floating around saying that scientists have found that fidgeters, yes they're talking about you miss-constant-pencil-tapper, are more likely to be thin than their less annoying fidgety counterparts. This all comes after they found a gene that they say accounts for the propensity to shuffle and shift. This constant movement in turn means spending energy that you didn't even know you were spending.

So I am curious about you guys -- Which category do you fall into?
