Really interesting as it shows how Fauci struggled.
Even more relevant after the above post.

Funny that the same people telling us that masks don't stop viruses getting in tell us that they do stop the 500x smaller CO2 molecules getting out.Lol...idiots.
But...that's true, though.
😬
Not all viruses are stopped from staying out - the masks "pores" are far too large.
Not all air can get in and out and you do pool CO2 under your mask as you wear it - if it didn't, you're wearing a wire-mesh mask.
Both can be true at the same time with no logical or scientific inconsistencies. It's because no "system" is perfectly this or that.
"Either the masks or perfectly porous or they are not! Nothing in-between or you're an idiot."
lol, okay

I remember him being more thoroughWhy didn't he do a long term test to see if there are any cumulative effects to long term usage of masks. I mean people that work in the public are having to wear them for hours at a time and some are doing heavy manual labor.
Due to the oxygen deprivation and the pooling of CO2 under the mask, one of the outcomes from wearing a mask for long periods of time throughout multiple days is an elevated hematocrit count. Your body naturally responds to the lack of oxygen by pumping out more RBCs.
The dude in the video mocks the anti-maskers by pointing out the elevation of cities and states being higher than recommended for oxygen levels. But what he fails to mention is the body's natural adaption to oxygen deprivation at higher altitudes and it takes a few days to start seeing those changes.
So, yes, a person will get light headed if they are not prepared/fit/healthy enough to be oxygen deprived when putting on a mask at first. If they wear it all the time almost non-stop, their body will adapt by busting out more RBCs.
And for those who may be science deniers, here's the best research on whether or not masks really can prevent respiratory illnesses (the answer is a solid no with the data pointing, in some cases, to situations where it increases the chances for respiratory illnesses):

Masks are not effective in preventing respiratory illnesses according to a large metaanalysis that made use of RCT where available, posted by the CDC:We did not identify any published research on the effectiveness of respiratory etiquette in reducing the risk for laboratory-confirmed influenza or ILI. One observational study reported a similar incidence rate of self-reported respiratory illness (defined by >1 symptoms: cough, congestion, sore throat, sneezing, or breathing problems) among US pilgrims with or without practicing respiratory etiquette during the Hajj (32). The authors did not specify the type of respiratory etiquette used by participants in the study. A laboratory-based study reported that common respiratory etiquette, including covering the mouth by hands, tissue, or sleeve/arm, was fairly ineffective in blocking the release and dispersion of droplets into the surrounding environment on the basis of measurement of emitted droplets with a laser diffraction system (31).Respiratory etiquette is often listed as a preventive measure for respiratory infections. However, there is a lack of scientific evidence to support this measure. Whether respiratory etiquette is an effective nonpharmaceutical intervention in preventing influenza virus transmission remains questionable, and worthy of further research.
...
In our systematic review, we identified 10 RCTs that reported estimates of the effectiveness of face masks in reducing laboratory-confirmed influenza virus infections in the community from literature published during 1946–July 27, 2018. In pooled analysis, we found no significant reduction in influenza transmission with the use of face masks (RR 0.78, 95% CI 0.51–1.20; I2 = 30%, p = 0.25) (Figure 2). One study evaluated the use of masks among pilgrims from Australia during the Hajj pilgrimage and reported no major difference in the risk for laboratory-confirmed influenza virus infection in the control or mask group (33). Two studies in university settings assessed the effectiveness of face masks for primary protection by monitoring the incidence of laboratory-confirmed influenza among student hall residents for 5 months (9,10). The overall reduction in ILI or laboratory-confirmed influenza cases in the face mask group was not significant in either studies (9,10). Study designs in the 7 household studies were slightly different: 1 study provided face masks and P2 respirators for household contacts only (34), another study evaluated face mask use as a source control for infected persons only (35), and the remaining studies provided masks for the infected persons as well as their close contacts (11–13,15,17). None of the household studies reported a significant reduction in secondary laboratory-confirmed influenza virus infections in the face mask group (11–13,15,17,34,35). Most studies were underpowered because of limited sample size, and some studies also reported suboptimal adherence in the face mask group.
Disposable medical masks (also known as surgical masks) are loose-fitting devices that were designed to be worn by medical personnel to protect accidental contamination of patient wounds, and to protect the wearer against splashes or sprays of bodily fluids (36). There is limited evidence for their effectiveness in preventing influenza virus transmission either when worn by the infected person for source control or when worn by uninfected persons to reduce exposure. Our systematic review found no significant effect of face masks on transmission of laboratory-confirmed influenza.

I did more research and it looks like I might be wrong. A meta-analsysis of randomized controlled trials on the efficacy of masks was undertaken, already.Jacobs, J. L. et al.

There were no statistically significant differences in preventing laboratory-confirmed influenza, laboratory-confirmed respiratory viral infections, laboratory-confirmed respiratory infection and influenza-like illness using N95 respirators and surgical masks. Meta-analysis indicated a protective effect of N95 respirators against laboratory-confirmed bacterial colonization (RR = 0.58, 95% CI 0.43-0.78). The
4 use of N95 respirators compared with surgical masks is not associated with a lower risk of laboratory-confirmed influenza.”No RCT study with verified outcome shows a benefit for HCW or community members in households to wearing a mask or respirator. There is no such study. There are no exceptions.
Likewise, no study exists that shows a benefit from a broad policy to wear masks in public (more on this below).
Furthermore, if there were any benefit to wearing a mask, because of the blocking power against droplets and aerosol particles, then there should be more benefit from wearing a respirator (N95) compared to a surgical mask, yet several large meta-analyses, and all the RCT, prove that there is no such relative benefit.
Masks and respirators do not work.

Fact check: Wearing a face mask will not cause hypoxia, hypoxemia or hypercapnia
ADRIENNE DUNN | USA TODAY | 10:16 am EDT June 1, 2020
This is how often you should wash your cloth face mask.
PROBLEMSOLVED, USA TODAY
The claim: Face masks drastically reduce oxygen intake, cause carbon dioxide toxicity
As states are reopening, health guidelines recommend that people maintain social distancing, practice hand-washing and wear face masks.
The use of face masks is encouraged by the Centers for Disease Control and Prevention and members of the White House's coronavirus task force to prevent further spread of the coronavirus, especially in places where it is hard to social distance.
Wearing face masks has become controversial — even political in some cases — resulting in misinformation about their effectiveness.
One Facebook post claims that wearing a mask for prolonged periods of time can drastically reduce the wearer's oxygen levels and result in carbon dioxide toxicity. (The poster said she did not know the origin of the image she shared and did not check to see whether the information was correct.)
Another viral meme featuring three people wearing masks while walking on a beach says face mask wearing "reduces oxygen up to 60%" and "increases risk of CO2 poisoning."
R-0 may be the most important scientific term you’ve never heard of when it comes to stopping the coronavirus pandemic.

Face masks 101
According to the FDA, there are two main types of masks, N95 respirators and surgical masks. Both are tested for fluid resistance and filtration efficiency.
N95 masks are more tightly fitted, making them more likely to inhibit the breathing of the wearer if worn for a prolonged period of time.
Surgical masks, which are disposable, and other types of cloth face masks are looser fitting, making it highly unlikely that wearers would see significant depletions in their oxygen intake. Non-N95 masks also are porous, allowing air to flow in and out and permitting normal respiratory functions, while limiting the release of respiratory droplets.
Prolonged use of N9t may affect breathing which is partially why sensible advice suggests not being out for a long time in one...

So as we can see from my post, the actual research does not support mask wearing as an effective measure to halt the spread of the coronavirus and other respiratory illnesses.
Consider that the recommendations from the WHO and CDC have changed multiple times on mask wearing.
But don't take my word for it, take Dr. Fauci's word for it:
