Fahsands eh? I’m hoping you’re winding me up, but people are strange…I don’t think there was anything special about the mask, just the wrapper, I’m told, was promoting the exercise.
Re foam mask effectiveness, dunno, havn’t seen any data on it, but I think its likely because there’s no wire so they dont conform to the shape of your nose. In winter, when my main concern is smog (though they are relatively ineffective against that), I use the foam mask inside a surgical one, because its washable.
I’'m due my second Moderna jab on the 22nd, so peak side effects for the start of teaching. Huzzah!
After that I wont be hugely concerned about protection since I think getting a real infection sooner rather than later may be an optimal survival strategy.
Course if it kills me I’ll look pretty silly.
