This is really interesting to me because it implies that shallow breathing for long periods of time is a bad thing. I previously assumed that it was a good thing, due to interpolation from martial arts training - breathing exercises -> body becomes more efficient at pulling oxygen from the air and using it. I think I may need to reevaluate my assumptions.
