1 I can't be the only person who finds it fatiguing to breathe through a mask. I go out shopping -- say, a trip to the supermarket that takes a fair amount of time, and by the time I get home the only thing I'm fit for is sitting down and putting my feet up (after putting the groceries away, of course) for awhile.

And I don't have weak lungs, despite my age. For years I've been a highly-sought-after lead alto sax player for big bands.

2 Dana, I can barely make a trip to the grocery store in those things. I have to stop frequently, and sit down when I can. It pretty much exhausts me and I'm ruined for the rest of the day.
