I had a yoga instructor years ago who recommended squatting while doing your daily bathroom ritual. He said it was better for your bowels, your muscles and gave you a little daily stretch. Of course in Colorado, this meant except for the occasional camping trip, balancing on the lip of the toilet. Scary concept. Embarrassing to explain to the ER doc how you broke your ankle.
I won't reveal if I tried this or not. At least without a beer or two.
Saw this toilet at Dvice that won a recent design contest. It would be nice to see a model (fully clothed of course) sitting (laying?) on the device. I believe you squat facing the wall.....but not 100% sure?
Here is a longer article from Arizona State University where the design students currently are attending.
