Firefighter ends mask debate once and for all. arthur- do you have a link i can use to get to that video of firefighter mask test? i'd like to send it to family- i knew enough from other stuff that it's not going to really protect them from covid, but now i'm really concerned about their health...thanks for posting, now i know it's not all in my head that i can't breathe well w/ a mask on! Ahhh...bitchute works a little differently. Here you go on brandnewtube: It is also on you tube. Well, at least for now. You can do a search on: "Firefighter ends mask debate once and for all."
