I don't shake my legs. Once in a while I scratch my balls (subtlety). I have found women in the office don't scratch their balls. They adjust their bra straps.

I don't shake my legs. Once in a while I scratch my balls (subtlety). I have found women in the office don't scratch their balls. They adjust their bra straps. Unfortunately I don't wear a bra, otherwise I'd join in. There do seem to be a lot of moles on people around here though. There also appear to be a lot of sex toys around (It's where I work, see my profile). What I'm getting at is that you are asking an environmental specific question. You probably find that the 'leg shaker' has a higher metabolic rate or is possibly on the thin side (studies have shown some people are thin because even when sitting, they keep moving).
