Jane Brody covers a breathing method to mitigate asthma. It's what my paternal grandmother taught my father when he was a little boy. It's what I discovered on my own, because no one got around to teaching me. For most of my adult life, a wide variety of people have commented that I should breathe more deeply, some with quite a lot of emphasis. Finally, some justification for the very shallow breathing I prefer.
IIRC, my friend J. also suffers from asthma, and this is how she breathes when she runs, and it pisses her off when people try to get her to change because she knows it would set her asthma off.
