On my trips to India, most of the homes there have squatting type toilets, which is great, I'm pretty regular but when I'm visiting India I notice BMs are more quicker and more satisfying. Also, I've seen old people in their 80's who use the squatting toilets and they don't have any problems with them and then I see some healthy teens here in Canada who can't even squat much less use a squat type toilet, on my last trip my nephew had accompanied me and even though he works out regularly and is in good shape he couldn't squat for long and had to use the western type toilet.
