Another loud breather here. I have had asthma since I was a kid and I learned early on that it was easier to breathe during exercise if I pushed the air out fairly forcefully on the exhale rather than trying to suck in hard (which seemed to be somewhat panic inducing and would worsen the problem). I do it even if I'm current with the inhailer prescription, just out of habit. Also, getting into a steady rhythm with the breath seems to help me "get through" some particularly strenuous activities. I didn't realize people found that sort of thing irritating. hmm.
