If a Korean amp lady does squats very well then chances are, she was born prior to the early 1980s. lol
Dining tables and toilets were not available in most Korean homes until the early 1980s.
We ate using a traditional lacquer low table instead of a dining table. I sat on the floor but my sisters would squat because it was uncomfortable for them to sit on the floor while eating.
And most homes had no toilet where you can sit comfortably and take a dump. We had a squat toilet in other words, the toilet was on the damn floor. If you google it, images will pop up. So all of us Koreans had to squat in order to take a dump.
We had our first dining table and a toilet where we can sit on in the early 80s.
So if any Korean amp lady can squat real well, this is why and they are at least 40 years old and above. lol
