It's not all hot airBy:
I have now been playing the bagpipes for almost 60 years. I first became interested in the medical aspects of piping at medical school and later had the opportunity to research the physiological aspects at the RAF Institute of Aviation Medicine. There is an old joke that pipers march up and down because it is harder to hit a moving target. Whilst that may, or may not, be true, there is a physiological benefit to marching in this way.
