I haven't read a better example of wishful thinking than this post right here. "Some random utube crap"? Are u kidding me? This is Osterholm, a TOP expert, on NBC, not exactly your typical fake news site is it? He's saying what he said in March LAST YEAR.
If you'd be smart, you WOULD watch it and learn that this virus moves in aerosols... why am I even trying.....
Funny though that someone would have the nerve to pretend to know more on some forum.... we are doomed...
I watched it and I must say I came away with a different conclusion than you,
1. He said wearing a mask under the nose means you are an illiterate moron barely able to stand upright AND its 100% ineffective
2. Masks ranging from cloths to other forms have a variable degree of effect.
3. N95 is the gold standard
4. He did not talk about transmission outwards, only inwards. This is a thing that have been gone over and over and over again that last year before it settled, the way I remember it, its more about breaking the transmission vector outwards (for non N95). Of course that brings the mandate for the vaccinated to mask up into focus.
