The picture below is from a Japanese Anime cartoon. The man on the left is engaged in deep thinking in the scene.
The man on the left side of the picture is sitting oddly. His knees are drawn up to his chest,
his feet are on the seat cushion,
and his buttocks are sitting on both the back of his feet and the seat.
Why would a person sit like that? The man gives his reason in the video linked below.
If you chose to view the video, why would sitting in the way the man on the left is sitting increase his deductive abilities?
The answer is related to how the human body is constructed and functions in terms of Yin Yang Theory.
