Yeah that is just stupid. Fact free rules. Teens have ZERO risk.
Oregon HS Track Coach Calls For Mask Lunatics To Drop Rule After Runner Suffers 'Complete Oxygen Debt'
What does insanity look like? It was on display Wednesday at the Summit High School track in Bend, Oregon where the mask police -- the Oregon Health Authority -- forced athletes towww.outkick.com
Oxygen molecules have a diameter of about 300 picometers. Coronavirus diameter is about 100,000 picometers, not surprising since each individual coronavirus is composed of thousands of atoms. Aerosolized droplets are larger still, whether or not they contain any virus particles.
...for sufficiently large values of ZERO.
It’s why I’ve said we should be doing surgical not cloth. The cloth masks are not designed to distinguish between aerosolized particles and air. Bigger gaps. The surgical and n95 masks are designed specifically with this in mind (though the surgical aren’t very tight fitting...if you can smell someone smoking near you then there’s an issue)
Maybe grandstanding... I saw it as more of an affirmative action issue. Protecting Asians from Race based admissions policies would make affirmative action initiatives hard to implement without impacting the Asian community. That also would explain the straight party line vote.
The question is better put to Senators Duckworth and Hirono.

No doubt he will continue to be a "trusted advisor to presidents". It's really f'ing annoying what we allow to happen - lol. I'm glad I'm not taking any of this too seriously.
You might want to read the actual paper. It doesn't say what you've "been saying".Been saying
The key assumption in the paper is the assumption that the air in the room is well mixed. In other words, they begin by assuming that viral concentration is equal in all parts of the room. This makes the 6 foot versus 60 foot risk conclusion pretty much inevitable.
The section "beyond the well mixed room" is much more interesting. It gives a detailed explanation of what air flow paths exist, and how masks, distance, and being outside each work.
The simple risk is called respiratory jet. This is the direct wind created by your breath and speech. It is also a region of higher virus concentration. The higher viral load extends about 2m if unmasked. If you wear a mask, the air is slowed and respiratory jet doesn't go as far. Instead, it mostly goes up as hot air rises. (Masks and distance out to 2m help with this part of risk.)
The less direct risk is just increasing concentration by being in an enclosed space. If I am sick and spend 3 hours in a room, then I have added 3 hours of exhaled virus to the air. The longer I spend, the higher the viral concentration. And, the longer you spend in that room, the higher your exposure.
Cloth masks and distance beyond 2m do not help with this part of risk. N95 masks or better ventilation do help. Or, just avoid indoor spaces and go outside.
In all, the authors give a really good description of why masks, distance, and being outside are helpful, and the limitations of each.
Recently she’s been saying a lot about duration of exposure.
It’s been the factor they’ve been missing and the key explanation I think that explain dads “masks work” v real world results.
I’ve also been saying that the 6 ft thing was pseudoscience particularly when indoors
dads mind just blows a gasket that I always seem to get there before his experts. Just teasing with this last part

If someone is smoking near you you probably aren’t indoors. If you are yes there is an issue. It continues to puzzle me why the simple measures to limit potential exposure are so hard for people to grasp . . . like those driving alone masked? Lol!
If you prefer: smelling someone sucking on a lozenge, the garlic they just had for breakfast, their perfume, or their gas (particularly since the latter may actually transmit the virus).
I was sitting next to group of four business people yesterday talking about their shots like they just got baptized. So proud of their accomplishments and even have dates when they got their first shot and when they get second. One guy was saying he has to go every 12 months for the rest of his life. My best pal got his 2nd and he was so relieved. He told me this is just like all the other flu shots and he will just get one every year. I tried to tell him this one is just a little different but he got super mad at me and then went low blow asking me when I will get mine. I told him for the 1,000,000 time that I'm against using body parts from aborted babies so old farts can live longer and not have any unexpected life challenges to come knocking on their door. I can;t wait for the sign that says, "No vaccine, no service." Cal State just told my boy he needs the shot or else. That sucks and puts pressure on young minds. Two years left to graduate and now being told you must take vaccine or no school for you pal.
If you read the paper, it only says that 6 feet is nearly equivalent to 60 feet. It never claims that 2 feet is equivalent to 6 feet. In fact, part of the paper gives a detailed explanation of why 2 feet is not equivalent to 60 feet- at least if the infected person is not masked. The paper does not address whether 3 feet is similar to 6 feet for masked people. A shame, because schools actually need that information.It’s been the factor they’ve been missing and the key explanation I think that explain dads “masks work” v real world results.

The paper also is firmly in the “masks work” camp:
“ We note that the use of face masks will have a marked effect on respiratory jets, with the fluxes of both exhaled pathogen and momentum being reduced substantially at their source. Indeed, Chen et al. (42) note that, when masks are worn, the primary respiratory flow may be described in terms of a rising thermal plume, which is of significantly less risk to neighbors. With a population of individuals wearing face masks, the risk posed by respiratory jets will thus be largely eliminated, while that of the well-mixed ambient will remain. “
In case you are wondering, the authors note that the unmasked respiratory jet risk is substantially larger than the ambient air risk. The ambient air risk only dominates if we all wear masks.
” There is thus a critical distance, A1/2m/(αtfd), beyond which the pathogen concentration in the jet is reduced to that of the ambient. This distance exceeds 10 m for fd in the aforementioned range and so is typically much greater than the characteristic room dimension. Thus, in the absence of masks, respiratory jets may pose a substantially greater risk than the well-mixed ambient.”
So, the authors are saying wear your mask, stay moderately distant, and limit your time indoors. Mask, distance, outdoors. Just like Grace has been saying.
Way to bend over to distinguish. I’ve said 2 things: the 6 ft thing is completely arbitrary and time reduces the effectiveness of masks. The paper and subsequent news quotes support that. And I’ve agreed all along distance/outdoors better (in the interview they actually pan masks+ outdoors...just outdoors would great)..where we disagree is trade offs we are willing to make and when (and I’m being generous here since you’ve ducked the offer to put your proposal with the benefit of hindsight on the table)If you read the paper, it only says that 6 feet is nearly equivalent to 60 feet.

I got two doses of Pfizer. How long is this offer good for?
My wife got her second today. No line in the afternoon at the church where she got the vaccine although we were told there was a line in the morning. The timing of shutting down the J&J vaccine was a shame. It felt like to me we had some good traction based on the increasing number of vaccines per day. Not anymore.
Which paragraph in the paper do you believe says that "time reduces the effectiveness of masks"?
I can't find that claim anywhere in their published research. All I see is a numeric analysis that, the longer you spend indoors, the higher your aggregate exposure. (True with or without the mask)
Are you sure the research papers says what you think it says?
