A question out of curiosity. What's the best way to stand in one place for a long time, say an hour? "Best" in terms of energy consumption; but mainly ankles, knees and muscle fatigue. Stand evenly on both feet? Or shift most of your weight on one foot in turns? Is there some "optimal" foot alignment?
I'm asking both for answers from experience and a theoretical explanation what and why :)
Update: not required to stand still. If you want to be precise, assume you can use no more than a square meter of floor, as long as you're standing the whole time.
