I forgot to mention how easy, painless and noninvasive, the test for COPD is. You simply breathe in, and then breathe out (and that is what is measured). You do it many times to get the best reading, and the technician coaches you to breathe out as long as you can.
Not a big deal - and I understand from reading Thomas' blogs on the subject that there ARE things you can do to slow down the progression if you catch it early.
SO - what are you waiting for? Get it done. We know here that knowledge IS power!
