have you retired to a town with a higher elevation?
I have lived all of my life at sea level. When I visit areas at a higher elevation, I have trouble being active because I am so quickly and painfully out of breath. Does one get over that after living with the thinner air for a while? We are looking at the southwest but even Tucson at 2,000+ feet seems pretty high. Please let me know if any of you have had any experience with this problem. Thank you.
