That's nice in theory. In practice I have reduced lung capacity and start suffocating after 15 mins of N95. What happens is that the whole air flow is harder to push around, and there is so long one can force breath. I presume that people with healthier lungs have an easier time dealing with it, but I find it very hard to believe the impact is zero. For fun, I just googled 'N95 reduced oxygen flow' and found this pearl from Stanford as the top result: https://digitalmedic.stanford.edu/myth/myth-face-masks-can-reduce-oxygen-getting-to-the-lungs-and-bloodstream https://digitalmedic.stanford.edu/myth/myth-face-masks-can-r... > Myth: Face masks can reduce oxygen getting to the lungs and bloodstream > ... Some masks mean you have to put more effort into breathing if you wear them for a long time. > ... If worn for many hours without a break, an N95 mask might potentially affect oxygen levels but likely not to a dangerous extent, especially in people who are healthy. 'put more effort into breathing' aka 'suffocating at normal breath patterns'. Oh, and it actually does reduce the oxygen levels, but rest assured citizen, it is nothing to worry about. It's just a myth. There is a word I'm looking for here, miss, misty, aha, misinformation.

I never said masks couldn't affect airflow and thus oxygen. I said a mask cannot affect airflow and thus oxygen more than it affects COVID. That is, the "masks do nothing to prevent COVID but cut off air supply" arguments are dumb. Personally, I don't consider that reduced airflow relevant to me or anyone I know. The people with reduced lung capacity do complain about having trouble after 15 minutes, but continue to wear them. In fact, people with reduced lung function are the most aggressive mask wearers I know.

  Free advice: Don't wear a mask if you have a day-long interview at a FAANG. Don't wear a mask if you participate in an athletic competition. You won't get peak performance for either intellectual or physical activities. Masks are not zero cost, they reduce airflow. And their effectiveness against covid spread remains to be proven, especially as strains get more and more infectious. Now consider that kids are forced to wear cloth masks all day long, day after day after day. This is a choice, there are places in the world where they are just as serious about covid as US, and yet kids can stay in class without masks. It's a rough tradeoff. I wish we could have an adult conversation, not pretend there are no minuses and masks are a no brainer in all situations. We have replaced conversation with Twitter sloganeering. An example: https://nltimes.nl/2021/08/23/school-year-starts-north-netherlands-amid-ventilation-concerns https://nltimes.nl/2021/08/23/school-year-starts-north-nethe... > In secondary education, teachers and pupils who have been fully vaccinated for at least two weeks won't have to quarantine after contact with someone who has the coronavirus. Only unvaccinated teachers and -students need to take a self-test twice a week. Teachers and students need to maintain social distancing, and face masks are mandatory in corridors and canteens. > In primary education, adults like teachers and parents must keep 1.5 meters apart. But for the kids, no restrictions apply other than the general rules like washing your hands regularly and staying home if you have symptoms.

    > Don't wear a mask if you have a day-long interview at a FAANG Why on earth wouldn't I? My O2 levels don't seem to be too degraded by a mask. And, even if they were, I would never expect to be hired by people who saw me put them at risk. I'm not sure I would feel comfortable accepting a job from people who would hire someone who wasn't willing to wear a mask. > I wish we could have an adult conversation, not pretend there are no minuses and masks are a no brainer in all situations. I've never experienced a negative from wearing a mask. Some people are really opposed by I just don't get it. It makes as much sense to me as people not wearing a seat belt because they worry about chaffing. > there are places in the world where they are just as serious about covid as US, and yet kids can stay in class without masks. Every state that lets kids run around without masks produces news stories about COVID spreading like wildfire through the schools. I don't know why I would consider that acceptable. Kids should not be forced to get COVID for no reason.
