The "experts" lied and threw away a lot of their credibility for no good reason. People got fixated on N95s early on and the "experts" downplayed the value of other kinds of masks to everyone's detriment.
Serious question: Why not? It's not like you are going to catch any disease from it.
I know I can't catch anything from my own germs but I'm willing to splurge on a new mask. Covid has made me a big spender in my old age.
