I see. Thanks for clarifying that! I already thought you were joking, but wasn’t so sure. Seems a lot of people didn’t get it as you intended.
You could consider adding a flag like /j, /i or /s (depending on context) to such comments to avoid confusion.

Please provide an explanation, preferrably with sources, if you think my explanation is wrong.

In case you are serious or someone else is serious about this:
Masks, just like underwear, are permeable. If they wouldn’t be, you would suffocate as no air would be able to reach your lungs. (At your rear, that’s just a consequence of low requirements towards the material, which mainly serves as a covering and being able to dry.) So gas molecules are usually not stopped to pass through your underwear or masks.

The main difference between, e.g. FFP2/3, masks and your underwear is the size of particles that are able to pass through. Your underwear will be able to catch some moisture of a juicy fart and probably some shit particles. However, most of the gases and smaller particles can pass through. Filter masks are able to stop most particles down to a certain size. For FFP 2 masks at least 94% of particles down to a size of 0,6 micrometers can be stopped. Particles smaller than that are likely to pass through. FFP 3 masks block at least 99% of particles down to the same size.

The thing with viruses like Covid-19 is, that they are usually expelled from an infected person via the respiratory system, that means, your mouth and nose. There, the virus cells are mostly soluted within the moist air you breathe out. Moist air means: there are very tiny (mainly) water particles which are spread over a certain volume of gas. And they are floating with the currents of the gas. That’s what basically constitutes an aerosol. Particles, tiny and lightweight enough to float with a gas (for a while).
You can see that clearly with spray cans. With breathing air it’s not so good to see with the naked eye.
Those moist particles, loaded with virus cells, are usually large enough to be filtered out by FFP masks. It’s not perfect of course, but it can help a great deal and contribute to prevention measures.

The stinky stuff in farts is afaik a pure gas and not an aerosol. (Did you know that in terms of gas volume, just about 2 % of a single fart contains the smelly chemicals?) Which is why neither masks, nor underwear help so much against stinky farts.

FFP masks are mandatory in jobs where dangerous smaller particles can enter your body. They help against dust, smoke and a lot of aerosols. But they don’t filter out pure gases. That’s what gas masks are for.

In terms of infection spreading, a neat side-effect of masks is that they can slow down the velocity of exhaled air, which helps to reduce how far the aersol spreads around a person. Trying to blow out a candle while wearing a mask isn’t as easy as without a mask, which demonstrates this effect.

Futhermore, there has been a study suggesting that wearing a mask for a while or wearing it during rainy weather can - up to a certain point - further improve the filter capabilities of such face masks, since the moisture accumulates on the surface of the mask (in- and/or outside) and by this forms another protective barrier.

Thanks for coming to my TED talk.

Your relatives should stop using facebook.

Samsung smart TVs already show a small ad on the home menu.

I wouldn’t say that it necessarily expresses a certain opinion towards women. I think a lot of people used it just because that’s how it’s done. It’s a piece history, a “fun” tradition. A lot of people didn’t even knew that this was taken from a pornographic magazine.

However, thinking critically about it and considering a lot of good points, it’s surely not “fun” anymore and I also think it’s better to stop this.

Yes, let’s just shove everyone into one drawer and completely forget that some do it for fun, some out of financial necessity, and let’s also forget all the problems it can cause when using such an image in lectures, research and similar professional settings. /s

For those, interested in an overview about more criticism, just head to the according section on Wikipedia.

Yes. I think so. It just takes an exponential amount of energy and/or time. At some point it will stop due to energy limitations. Or will be stopped because computation time approaches infinity, even if all energy in the universe is available.

Also, now I think about the movie “The Thirteenth Floor”.

That’s also what I meant by capitalism “in it’s current form”. Yes. ^^

They just fuck with Kenyans. And that’s obviously okay, because they are not part of the western nations. /s

What? Unbelievable. I’m shocked. Shocked, I say. This really comes as a surprise. I would’ve never expected this. No one would have seen this coming. This is really outrageous. They are innocent. I can’t comprehend this. No way! It’s not acceptable! /i

– Apple Fan, probably (without the irony flag then)

Capitalism – in it’s current form, a system where some exploit others in order to make profit.

Aaand there goes another service again, which I’ve never used and now will probably never even think about using.

That’s why you need several security layers and failure protection systems.

That’s not separation, but a different ethical concept or a lack of thought about one.

First the EPP is center-right, not conservative right-wing.

As far as I can see it, they are conservative-right wing. It’s even clear from the first sentence of the Wikipedia article you posted further down:

with Christian-democratic,[4] liberal-conservative,[4] and conservative[5][6] member parties

Second there’s too much leftists’ bullshit already in EU member states

You mean like those competiveness laws discussed in this post?

that only benefits the USA

Sounds like a conspiracy myth to me. Feel free to elaborate.

You can use E2E??? !!!
