@carnage4life This doesn't surprise me, it's movement that's protective. I work either lounging or standing up because chairs are my personal nemisis (my back hates sitting on chairs for long periods). But when I work standing up I tend to be moving around more too. Just standing in one place all the time isn't great, as most blue collar workers with jobs like that will tell you (especially if it's standing on a hard floor). Basically our bodies like to move and evolved to be moving or lounging around. Just standing in one place or sitting in a chair for long periods is pretty unnatural behaviour.
