I used to have to wear a mask when ever we were sawing yellow pine (ponderosa or bull pine). Now, in Covid times, I wore one to get my eyes checked but had to take it off because it caused the instruments to fog. We had wear masks in Calgary, when we went to a tractor dealership. Once inside nobody seemed to care so we took them off. Every one knows, or should, that masks won't protect you from any virus but may reduce the virus you may spread if you are infected. If you are not infected (and the vast majority are not), you can wear a mask, if it makes you feel better, but you are accomplishing nothing. Probably the dumbest thing I see is when a group of people, all of whom KNOW they and their friends are virus free. gather together, all wearing masks. GD
