Bob, when talking about blowing into a device to test the lung function at the physical, I had the same experience as you that I had to blow it several times before the nurse said OK. It was like this in the last year check up and the same happened this year. The doctor said I lacked exercise but when I told him I swim every day for 30 minutes, he said that maybe I didn't how to blow!! So the report said 'mild restriction'. Since my x-ray reports for both years were fine and clear, I didn't bother. At this stage, our lives are full of alarms, true or false. Whether you are ready to take them, they are here. Best of luck to you Bob and I trust it is another false alarm, just like what I went through in July.

Karen.
