I am not a nurse or doctor and am not wearing them for 12 hours shifts, but I am wearing masks to work (I am a pet groomer) and I am struggling, so I have nothing but respect for everyone who has to wear them full time for a complete shift. I have yet to find a comfy mask that doesn’t hurt my ears, prevent my glasses from steaming up, or make me feel like someone is holding a hand over my mouth and nose. And Brogan, that day you were emptying your bins I was washing dogs in 30 degree heat trying not to pass out. We are in the same storm, but definitely not the same boat.
