Glad to hear that exercize has worked for you.

>Add up enough of all these tiny things over the course of a day, things you probably don't even realize you're doing, and each tiny fraction of a calorie expended eventually pushes you to the levels you see with more regular exercise.

Fidgeting will obviously burn some calories. But I find it hard to believe that fidgeting will burn the same amount of calories as sustained exersize.

I have heard some suggestion that the extra energy is being burned at a cellular level (causing inflammation). But would be office work get hot if that was the case?
