The number one joy in life is breathing. There is no question about it. When given the choice of any two things one might do, exclusive of the other, breathing wins, hands down. Especially if the exclusive length of time is more than, say two minutes.
So, if you are willing to give up breathing for something else, then that is something! Giving up breath is giving up life. If there is something you love more than living itself, then that something IS the meaning of your life. It is a simple equation.
