Random YouTube videos are not scientific research. Masks are not a new idea for repair diseases but thank you for again reiterating that you don’t understand the purpose.There are plenty of people that work in the medical field - and I'll leave you to look that up on Youtube yourself - that say they are not meant for healthy people to wear nor are they meant to be worn for a long time.
Follow the money with this thing. Always follow the money. Who is manufacturing the masks and who is making money off of this? It might give you insight as to why it gets pushed as much as it does.
Ah yes, how could I have forgotten about Big Fabric. I’m guessing you’re now a nudist too so as to not line their pockets?
