The humpback that only requires moving the neck up and down by 1 cm is caused by the head position shifting forward. The double chin is caused by the sagging of the neck by tilting forward. By moving the neck by 1 cm and loosening the muscles behind the neck, the head can be returned to the correct position. This is a lesson to create a bad constitution with a beautiful posture.
