Yet another benefit to masks, Erik, discovered (by me anyway) last week: my nose started dripping, and I didn't have a tissue handy, but I couldn't think of a way to keep it from leaking down into my mustache, so...
Nobody but me knows my nose is running. So what if my mustache is soaked with snot. Nobody knows but me!
And when we got back to the car we did the hand sanitizer thing, I took off the mask and dropped it into the "to be laundered" pile, dried my mustache and blew my nose with the tissue stash in the car. All good! (And then sanitized my hands again. At my wife's suggestion. Yes, dear.)
