Obviously someone should investigate what's causing that brain damage. Thankfully we have quite a number of subjects to study here.
I have a hard time believing that any of these mask are truly filtering the air being breathed.
Take your mask and just hold it tightly over your mouth and try to blow air through it.
It is very hard to do so why would you think that air is easily flowing through it when you breath.
I think the bulk of the air being breathed is going around the masks.

I’d probably walk back “any,” as anyone who wears a mask with a proper seal will tell you.
That said, I haven’t found a need to wear an N95 or similar mask yet (luckily), even though I have them and have them fitted properly
Personally, my daily routines are relatively low (exposure) risk as long as the COVIDiots stay home. A 3-layer cloth or paper mask is what’s being recommended, and not being a medical expert myself, I can live with the risk that my masks are less effective than a mask with a seal.
If we’re at a point where PH says we need masks with seals, I’m probably staying home anyways.
I tend to wear ear protectors for long excursions and at work, which pulls the mask taught enough that very little air is leaking. But some masks definitely ‘seal’ better than others with/without that.
So, I’d say if you think you have a lot of “leak” and are concerned about your mask’s effectiveness, maybe you need different masks. Or at least stop going to places where having a seal is likely to make a difference in terms of your safety.
Without significant leakage, people would be suffocating because it is very hard for air to pass through most masks.
Put your N95 tight over your mouth and try to blow air through it. It is not easy.
I am talking about a simple test to see how easy or difficult it is for air to pass through a mask.
What you seem to miss is our breath is not composed solely of molecules of air (N2, O2, etc). They are much much smaller than the droplets and aerosols that are the main transmission vectors for covid and move much easier.
Yes, our normal lung function makes it more difficult to force our breath through the mask but none of the recommended masks, even N95s will produce a noticeable reduction in blood oxygen levels (except potentially at exercise levels where our body is already starting to have difficulty processing enough oxygen).
BTW. I wonder how the board would react of TJ's thread was "Take Off Your condom Take Back Your Freedom"
My point is that I believe the bulk of the air that we breath is not going through (filtered) the masks.
If it is very difficult to blow air through a mask, it doesn`t make sense to think the air is freely going through the mask when we breath.
The path of least resistance is not through the mask, even if it is a snug fit, unless it is a useless mask that is blocking nothing.
I guess what I am wondering is how much do masks protect the wearer if they are not filtering the air that is breathed?

It is cold out today so here is an easy test.
When you exhale droplets in your breath condense when they hit cold air.
These are the droplets that can potentially carry covid.
Go outside and exhale without a mask, notice how far you can see your breath.
Now put on a mask and exhale and observe the difference.
This can be done with any type of mask you want to try and will show you how much your mask is suppressing the droplets that can potentially carry covid.
The main objective is to limit dispersion to within 18 inches.
You completely missed my point.
I am not talking about blocking droplets, of that I have no doubt.
I am talking about how much protection masks offer the wearer.
You can believe whatever you want but this stuff has been tested. As long as you're not going around with the mask under your nose, most of the air you breathe passes through the mask.
Masks are mainly for protecting those around you.
This was one of the first things that Dr de Villa taught us.
Most are more shield than filter for the wearer, unless it is a respirator.
I wear masks.
Of course I would like to think they are protecting me as much as possible.
I am just considering the physics of blowing air through the masks, and how extremely hard it is to do.
If the mask edges were air tight, I would suffocate very quickly.

Correct. They offer some protection for yourself but that is not their main use. Health officials worldwide have been consistent in telling us that.
And all masks allow air molecules to pass through, even respirators and gas masks. Fact is molecules of O2, N2, CO2, and what-not are much smaller than any droplets or aerosols that could carry covid. As I mentioned before, there are numerous studies about masks and blood oxygen levels that show no noticeable difference whether it's a cloth mask or a properly sealed N95 respirator.
You will continue to believe what you want but there is actual scientific data showing your belief is wrong.
You don`t seem to comprehend what I believe so any conclusion you have is irrelevant.
If you believe so strongly that most of the air is being filtered, why is there now a lot of talk about double masks from places like the CDC?
The Centers for Disease Control and Prevention (CDC) concluded last week that new ways of wearing face masks dramatically reduce the risk of contracting COVID-19.
First, the agency said, users should fit a cloth mask over a medical procedure mask — essentially wearing two masks — to increase protection.
Second, the agency said, knotting the ear loops of a medical procedure mask and then tucking in the excess material to flatten the extra material close to the face increases the virus barrier.
The three-ply masks, which may be flat pleated or cone shaped, are not designed to protect against infections from viruses and bacteria but rather to prevent contamination of sterile surgical sites and to prevent blood and other fluids from splashing onto the wearer’s mouth and nose.

No I get it. You find it hard to breathe through fabric so you have the mistaken belief that it can suffocate you.
It's not possible. The worst that could happen (for people with normal lung function) is you can have a panic attack because you feel your breathing is off.
As I said, there are numerous studies on blood oxygen levels of people with masks and masks/respirators don't make any significant impact.
