Your breath happens so naturally that you often give it very little of your conscious thought or attention. Breath is life, it nourishes and supports your nervous system, it shows up in how you express your impatience, your relief, your exertion of energy and your ability to self regulate.
We are all predominantly a society of shallow breathers that manage to negate the importance of it, to notice its characteristics and just how it supports and sustains you on a day to day basis; because you are simply too busy or caught up to notice.
