All good points, especially the lung bit. As we have seen it is all about how these covid variants are affecting the respiratory system. I have invested in a holistic 'lung support' and other such remedies to use as 'added barriers' for when I'm out in the crowds. When I was working through it all, at a grocery store, upping my immunity was the name of the game, for sure!
But you're right...sometimes what I really need is some good old fashioned Alka-Seltzer! ;)
