[FRIAM] New information on COVID-19y bb

Excellent idea.  After reading the article Merle linked, I ordered one 
myself.

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.

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.
