You make it sound like masking for a cold is as obvious as knowing it’s going to rain. When was the first time you wore a mask when you realized you had a cold? (Serious question; not rhetorical.) I have to say, I don’t know anyone who thought that was an obvious thing to do until 3 years ago. In fact, I know a few people who still wear masks every day, but otherwise, no one I know does it anymore, even if they have a cold. I don’t think there’s anything obvious about it at all, if obvious means something that everyone can see.
