| The average person breathes at a rate of 12-18
        breaths per minute. People under stress breathe more, and calm people
        breathe less.  You can improve you level of calmness by learning
        to breathe slowly, eg 6-8 breaths per minute.  This is also better for your health, as slow deep
        breaths allow your body to get all of the oxygen out of the air, and to
        fully expel all of the bad air.
