Oh yes, constantly.....been doing it for years....since I was a kid
My and one of my younger sisters do it all the time....
It's like I can't ever just be still....it's funny really.
For instance, Me and my family will be at church.....we take up one whole pew.....my sister and I will be unconsciously doing this and my step-mother will look at us both and tell us to stop, lol.
Or when I'm at the movies with my husband or mother, they always end up putting their hand on my knee and tell me to stop....they laugh about it, lol.
But, most of the time I don't even realize that I'm doing it....it's automatic.
I've never seen anything wrong with it.
I just smile and go on with my life
