Abstract

I have been breathless for a long time. I lagged behind others when walking uphill. I became breathless when dancing. I couldn’t play tennis. But I somehow convinced myself that this was normal. I was getting older—perhaps in one’s mid-30s fitness drops like this, I thought? Perhaps I have “small lungs,” my husband speculated. But we were both physically active, and as we were living in Australia at the time, we enjoyed bush-walking, bike riding, and the sunshine that permeates outdoor life down under. So I masked my breathlessness as best I could, and never went to see a doctor, despite my clear and increasing respiratory difficulties.Two years went by. We returned to live in the United Kingdom—in hilly Bristol..
