Fret not. It's normal. I do it too. And I did it when I was not an engineer. As a primary school student and then as a secondary and then college student. I think it's good for us engineers. It gets us little bit of movement for otherwise immobile ourselves. I even move around my legs and I stretch it a lot and when stretching I forget that my workstation switch is right in the corner and I switch the entire damn thing off once or twice a month - that was the reason I had to get my (our corp) backup settings on my PC modified to a little more frequent period (15 mins from an hr). Happy shaking!
