btw, if you do get Covid ..do the breathing with a spirometer. YOu dont even need one to have the same effect.
I recently had a pulimonary breathing test. I passed it fine but I had to stop in the middle of it because I was coughing up so much clear phlegm.
The guy told me that was common to see during the test.
WHO claims not true..but they are worthless
