Interesting, useless experiment. It was invalid from the start. He went in 'knowing' that standing for long periods 'made' him sleep better. That may or may not be true. It is anecdotal. Not only that, but he may have drawn the same conclusion that standing on one leg also worked and that doing 4 sets was best, etc. I'm not saying that standing's effect on sleep doesn't warrant proper exploration. I am saying that the placebo effect cannot be ruled out with this guy's work.
