No need for the patent, no one will steal this idea, no way! That women need some cloths on, this is 2010, who squats now (apart from some areas).
Actually, a lot of Asian countries have the squat version. It's suppose to be cleaner, but if you miss you target, it's a mess.-shock If you're not used to it, it's going to be hard to get up if you squat too long.
Squat toilets are common around the world because toilet fixtures and plumbing is expensive. It had nothing to do with hygiene. I've seen squatters in Europe, the middle and far east. The only place where they're "rare" is in the US.
i think squatting is possibly better for long term health. i mean when u reach the ages of like 80-90 i think if u've squatted all ur life u could be more agile and will be able to squat. otherwise u will just fall into the toilet haha.
