But what if you are sick and contagious, but you don't know it yet because you aren't showing symptoms?
There are a lot of possibilities. I don't really see the sense. If you have no symptoms you aren't sneezing and hacking particles all over and I don't really see much use for masks. It is just a matter of probability. Your odds of dying on the road to the event are astronomically higher. So by venturing out my front door I already faced a greater danger than no masks.
Now if your are making my food I may feel differently. Or is McBeth a close talker??
