Oh, but the Asian squat... that's a whole different can of worms.
haha, yes that is a really amazing thing to me. I have seen Asian women squat for very long periods of time preparing food or washing dishes in a bucket (or clothes) and they hold that position effortlessly. I tried it one day and was complaining after just 10 seconds. I truly is amazing.
But things like what you are talking about here are important. IN my travels I see a lot of faux pas done by new travelers mostly and it is embarrassing for me to see even though I didn't do it. I never knew this about Japan but I wouldn't be sitting on the ground anyway so it doesn't apply to me.
Very easy to read article and just great overall structure. You are talented!
