The mask. Am I the only person who realized that they never had even a cold while we were all masked for Covid?

I don’t care if Covid is over, not over, or of unknown status, I’m wearing a K95 mask any time I’m in an enclosed space with other people. Usually I’m the only one, and I do get The MAGA Look now and then, but I do not care and have not had even a sniffle since before COVID!
