What does the Gregorian calendar mean when a hunchback bends like a bow?

Everyone wants to be tall and straight, especially the girl with a beautiful swan neck. I think this has something to do with the ancient people's psychological attitude of bowing their heads and knees in front of high people. If they succeed, they will be proud. Being able to breathe freely is related to the psychological pressure of not relaxing. When hunched, the chest is tight, which drives the muscles of the shoulder and back to sink. Bend like a bow. Now people have to live a humble life, and their bodies and minds are stretched. Yoga also helps. Yoga can clear the heart and relax yourself. Using this yoga aid on the back can relax and sleep straight.
