More bullshit. Denis G Rancourt the disgraced fired University of Ottawa physics professor wrote this. His article was deleted from Research Gate. It’s especially hilarious when he gets confused over whether 2.5 um is larger or smaller than 0.3 um. You don’t read or understand the crap you post.JerryRig wrote: ↑Sun Dec 26, 2021 4:14 pm
Knowing that there are no studies concluding that masks prevent illness and lots of information, anecdotal or otherwise that masks are harming both physically and psychologically, can you tell us why you think this is not safe? Would you be open to looking at the evidence? Do you not trust your God given immune system? Also, do level 4 biolabs consider procedure, surgical or cloth masks
For more reasons why this article is useless and you’re again posting bullshit, here’s a nice light read (but JerryRig you won’t understand it):
