You just made me feel a lot better. I have had a few times when I couldn't breathe, but it was only for a moment. I got better by just sitting down. I do get desperately short of breath with physical activity. Again, this gets better if I slow down.

I have been envisioning this sudden crisis in which I will stop breathing, sit there unable to recoup, and suffocate to death while fully conscious of the entire thing. Maybe this is not so very likely after all.

Thanks for making me feel better.
