I mentioned this in another post, but here goes again. Myself, my sister and brother had all sorts of breathing issues when we lived in Oklahoma, where we were all born. My parents asked the doctor what to do: he said move to Hobbs, New Mexico. It is high, like a mile high, and dry. We did, and none of us had breathing issues again that I recall. Now I do again–because I live in Ohio. Back to New Mexico soon!
