Lol, to visions of large westerners trying to squat!
It's a useful position for gardening too, when you don't want to let your bum touch the ground where there might be mud, chicken poop, wet or just cold. Unfortunately, whenever I stand up after a while of squatting my feet have usually gone numb! 😆 I have to remember to shift my weight up off my calves occasionally, to let the blood flow more freely.
My youngest daughter struggles with this flat footed, because her achilles don't have much flex. She used to walk around on her tiptoes all the time when she was little. It means she's pretty good at pointing her feet for dance and gymnastics, but she has to balance on toes when in a squat.
