The good news is that studies have shown masks aren’t all that effective so no one needs to worry about this anymore. If you want to wear a mask, ok, if you don’t want to wear a mask, ok. Also, COVID mortality is way down. Any concerns about masks or COVID can be relegated to statistical insignificance when it comes to trying to control other people’s behavior.
Is it so effective that you need to be concerned if other people are wearing a mask? Also, that would be quite a different concern than this submission is hinting at.
