> Yes, mask may work in some circumstances, but everyone wearing them all the time in social settings?

I found it pretty obvious almost two years ago already that N95s are pretty good at filtering particles (even smaller than rated) and that most people are pretty bad at using them consistently. Further evidence is great, but I wonder if people really are surprised to find this out.

One thing should have been obvious to everyone at all times: You cannot eat while you wear a mask. People take their masks off all the time to have a meal together. What's the point of wearing a mask for the rest of the day then?
