When I was a kid I slipped in the bathtub (that was before there were showers) and hit my side on the edge of the tub. It knocked the breath out of me. I thought I was dying. It was a terrible experience. I don't know how long it lasted. Breathing. Something we take for granted. They have machines to help. Some folks have to carry oxygen tanks with them 24/7 to facilitate the simple act of breathing. Have you ever been unable to breathe? Why?
