That's easy if 'sitting on your ass' amounts to grazing on facebook, watching idle entertainment or playing games. For the rest of us who work on a computer at a job and/or then again at home, that's a bit impractical at best and not the least feasible for many, even some who happen not to be hamsters in a cage. And though a treadmill is a bit extreme I see no reason to shrug off standing desks as an annoying fad--it's just as natural a position to work as sitting though not as culturally ingrained, and uncomfortable for long straight hours (but then sitting is seemingly comfortable while not at all healthy).
