Mao Zedong was the biggest murderer in history. He killed about 75 million of his own people.
Mao did not move with elegance and ease and his Little Red Book contains no exhortations to free the neck so the head can release forward and up.
Mao was stiff. He tended to tip his head back, to lock his neck, and to pull down and in on himself. I wonder if his genocidal impulses came from all the unnecessary tension he put on his cervical spine?
Mao was fat and like many people with big bellies, he tended to tip back from the waist and to compress his lower back.
