When you would cough or sneeze pre covid, would you cough into your hand or shoulder, sneeze into a tissue or something? Unless you are an animal, of course you would; limiting the amount of your snot, phlegm, spit etc going out for others to ingest.

So ill break it down for those with pea sized brains..think of a face mask as a tissue, hand, and shoulder that is attached to your face.

It is common sense, not political.
