From the "things we already knew" department, in the "you wouldn't listen" aisle.

One study the German researchers looked at found that just 0.3 percent prolonged CO2 exposure to both pregnant rats and young mice led to brain damage, heightened anxiety and poorer memory. Another found that male mice exposed to 2.5 percent CO2 for four hours — equal to 0.5 percent for humans — resulted in the destruction of testicular cells and sperm. A third study found that three percent CO2 (equivalent of 0.8 percent for humans) in pregnant rats caused stillbirth and birth defects
Alluding to the surge in stillbirths during the pandemic, the German researchers said: 'Circumstantial evidence exists that popular mask use may be related to current observations of a significant rise of 28 percent to 33 percent in stillbirths worldwide.'
The German research team gathered data from 43 previously published studies on exposure to CO2, mask-wearing and pregnancy.
They found that after wearing a mask for more than five minutes, CO2 levels in the inhaled air rose to between 1.4 percent and 3.2 percent.
But the study could not conclusively prove that the masks were directly responsible for any of these complications.
The main caveat of the research is that the studies looking at the potential toxic effects of carbon dioxide are animal studies - because these experiments would not be ethical in humans.

So now you have people working physical jobs that push their aerobic limit even when they aren't wearing a mask, and now doing it with a mask on. We had the knowledge pre-covid to know that's not a good idea.
These people need to burn in hell.

It lets both through. But it also acts as a buffer for the volume of air between the mask and your face. Normally all that would drift away before you start breathing in again. Instead, you repeatedly re-breathe the last of what you just exhaled. Virus, bacteria, fungus, CO2 and everything else.
Incidentally, that is also the part that has the highest CO2 content, because it's the first of what you previously inhaled, and what reached the deepest parts of your lungs. And now it's the first of what you inhale again. And over and over again.
Not to mention the mask acting as a petri dish, kept warm, and moist, and dark, and well fed. For all sorts of things to grow and multiply. Some of which get dislodged and go for a ride every time you inhale and exhale. Just what the doctor ordered.

I apologize, "midwit" was clearly a gross overestimation of your mental capacity.

All you can do is repeat variations of "Masks stop air but not viruses."
The mental gymnastics on that stupid shit is "Galaxy Olympics" grade exercise there.
You should look into cult-deprogramming. Or suicide because once you get to this level of abject retardation, there's almost no coming back.

Just like the coffee filter lets both coffee and water through, and yet you still find some of both stuck inside it.
It appears this is a nuance which is beyond your ability to grasp. Keep wearing your face diapers. Nothing of value will be lost.
