Those little Oxymeters that clip onto your finger are cheap,
and available at most any pharmacy.
Get one, folks, and show people what they have been
frightened into doing to themselves and their loved ones!
Starting with "Hypercapnia".
(Especially if you already live at any altitude!)
Most everyone will show a few % blood/oxygen sat. loss
at least, after even just a few minutes being masked.
(with most masks.)

Oh, and bring your alcohol wipes and UV sterilization wand
to sterilize the Oxymeter for the Karens, before setting it
somplace they can safely get to it, to try it out for
themselves..
