Me, a fool, who knows that I often just keep going: "I will do a tiny little bit of snow shoveling as a practical fit check of one type of these new N95 masks."

Also it's not ideal weather for such a fit check, since it's above freezing and my glasses don't fog as readily in warm temperatures. I don't often say "I wish it was colder" but this time is one of them, it would have been a better check in say -5 C. Plus I probably wouldn't have sweated as much.
