Oh I meant when they were sick, not all the time. Sorry - yeah, that's a bridge too far.
This is a good idea for those who are sick so they can't spread the disease through coughing or sneezing. But wearing a mask has benefits for the healthy too.
Funny thing is, how many people feel now is how I've felt for some time haha - Touching hand rails, elevator buttons, doors, it all already bothered the hell out of me. Hell, I couldn't go buy a Monster Energy drink from the gas station without wiping it down.
This is why one doctor from Cornell Medical Center suggests wearing a mask, or even a bandanna, if you are healthy as the benefit is that it keeps you from touching your face after touching any of those things you mention - at least until you can wash your hands or use hand sanitizer.
