It’s impressing how cultural tradition influences the human body. No matter where you go, across Asia you see men and women above 80 years old cowering ( I don’t know if this is the right term – sitting on their heels, knees completely bent) at bus stations or other places in a body position that most people of the western world at half the age could not stay longer than 5 minutes without pain.
There are also nice videos on youtube showing japanese carpenters at work. Unfortunately it’s only a few.
I enjoy working wood in Germany.
