<p>Excellent idea. After reading the article Merle linked, I
ordered one myself. <br>
</p>
<p>I also found that rumor has it that an oximeter will be built
into the next Apple watch and the next Watch OS. There is also a
possibility that the software will work with existing Apple
watches. <br>
</p>
<p>I just made a suggestion to Apple that IF the latter is true,
they might consider releasing that part of their software as an
app now. I.e., not wait until September. That would be an easy
way to get something helpful out now, rather than injecting
disinfectant as our esteemed leader has suggested as a cure. <br>

The point is that if you check your blood oxygen level you might
catch the problem before it is so bad that you have to be put on a
ventilator and probably won’t survive.

the burden of the Times article was that IF you are
sick from a “cold”, don’t wait to test your O2 levels
until you EXPERIENCE difficulty breathing, because by
then it might be too late. Do you all have colds? I
suppose, given that it takes Amazon six weeks to get
