Posted in: Japan seeks to make online insults punishable by jail time See in context

Complete bs.

Specially in wake of the enforcement of non legal rules against insults by social networks, they already have shown that there is no way in hell this is going to be fair, reasonable or useful.

There are heated arguments in real life, and people might end up insulting each other in the heat of an argument in real life, even if they do not mean it, and that in itself has never really been seen as a problem.

But when it comes to online stuff, basically the same thing now is been regarded as a crime?

This will only be another wall to freedom of speech, since people will be afraid to say anything negative against anyone, since it could be constructed as an "insult" and therefore "illegal".

Making insults illegal is one of the most regressive and stupid policies, but it fits perfectly this brainless society that started last year.

Using the word "retake" is misleading and completely following the CCP narrative that Taiwan is a "rebel province".

The historic reality is that Taiwan is the remanent of the Republic of China, which existed way before the CCP, and as such, Taiwan has never been under CCP control, and was the only part of the original Republic of China which was not invaded by the Communist Army.

It wouldn't be "retake", it would be an invasion to "TAKE" something that is not theirs.

Posted in: Quarantine remains biggest deterrent to air travel See in context

You don't catch Covid from foreigners or by being abroad. You catch it according to your behaviour around others.

That has become kind of the moralistic view on viral infection, which believes that getting infected by a virus is because you didn't do enough, or you didn't "followed the rules" or whatever you believe is "bad behavior".

Sadly virus doesn't really care about that, and blaming people who get infected by a virus with a very high R0 number is just going back to medieval times when people believed that diseases were demons getting inside of sinners because of their sins.

Posted in: Have you had a long-term friendship, work or family relationship break down over COVID issues? See in context

Just like, restaurants, bars, gyms, dance studios, care homes, pro sport event's, etc. Oh and good luck with international travel.

I support vaccination, but not at all mandates or people who try to force it, and just like the lockdowns, in the long run I think these measures are likely going to generate more harm than good.

I mean, right now, even getting vaccinated here in Japan, you still have to quarantine for like 2 weeks, not only that, if you don't live in Tokyo, which has most of the right now mostly dead international airports still allowing some flights, means you will require not only the 2 weeks, but money to be able to stay in some place that allows your quarantine, and the fact that Japan isn't really recommending or implementing so called "vaccine passports" to be able to enter somewhere, it means that at least in this point in time vaccinated people do not get any real benefits in that front.

Not only that, at this point in time SARS-CoV-2 is for all intents and purposes no longer a high risk virus, not only there is already a very effective vaccine against serious infection, but before this year ends there will be available an antiviral medication that supposedly also works very well.

Continuing to treat SARS-CoV-2 as if it was March of 2020 makes no sense, and it helps no-one.

But it has really become more of a moralistic battle, with little to no compassion or attempt of mutual understanding of others.

Posted in: Have you had a long-term friendship, work or family relationship break down over COVID issues? See in context

It's not just about me, anyone who's smart enough wouldn't let anyone in their house who isn't vaccinated.

I agree it is probably not virtue signaling, but I think it is mostly anxiety, and a lack of understanding of risk.

The vaccine is non sterilizing, and recent studies based on data on the wild on transmission, put the infection protection at around 30%, but it still provides excellent personal protection to not get a serious infection.

So basically, you are only lowering an extremely small amount of risk by discriminating against family members, which I suppose you love. So from that point of view, if you really believe you are lowering some kind of high risk by discriminating against others, you are not. You already took most of the risk that is posible by vaccinating.

Not only that, understanding basic human psychology, your discrimination is more likely just hardening his position, because no one likes to be discriminated in that form. So you are probably just pushing your family member into a deep depression, while doing nothing to little to actually help that person, or make him take the vaccine.

Posted in: Are you in favor of vaccination passports for international travel? See in context

I've been against all border measures, just as the WHO originally was, after the initial outbreak, when the illness became endemic to so many places around the world.

The measure is arbitrary, it doesn't stop the virus, since it is already inside the country, and unless you also have internal borders in your country, it is inconsistent.

On top of that, forcing vaccinations for international travel will mean that there will be a 3 tire system around the world for travel.

1st Tire are all the well connected and powerful, which can have exceptions specially made for them, and are allowed to travel without much problem.

2nd Tire is for vaccinated with (Accepted) vaccine passports, still with restrictions and hoops one have to take.

3rd is the rest, including people who cannot get vaccinated for medical reasons, people who are vaccinated but cannot get a "passport" for it, or the info they have is not "validated", people who cannot get vaccines, and people who should not be vaccinated in the first place, like small children. These people will have in many cases their lives destroyed.

Once again, this is a measure that is coming out of irrational fear and panic, it is not well reasoned, and it will create way more problems that what it supposedly solves... and it will be implemented in many places.

So get used to having to prove that the vaccine you took is "the good stuff", that and to have to probably vaccinate with different brands depending on the country you are going to, and still not be able to enjoy your freedoms as they once were.

Posted in: Japanese researchers show masks do block coronavirus, but not entirely See in context

This is not a low quality study and cannot be made on science fair experiments. There is extreme importance in corroborating what is though with this virus, not with random aerosols, and with a controlled environment and precise methodology and measurements in order for it to be done. A lot of times what is though to be obvious turns out not to be so (like not transmission from asymptomatic carriers).

I asume you haven't read the literature on mask transmission.

No one is negating that masks are a physical barrier, there have been a lot of studies just like this one that basically show the dynamics of airborne particles when you sneeze from a mask, or breath or whatever, this isn't new.

In fact, before this year, exactly this kind of studies promoted by the WHO were used as a way to show how masks aren't good enough. I remember not so long ago how a similar study was used to basically say that people should try to sneeze and cough in their elbows, and to not think that because you have a mask there is no problem. It's really crazy how the narrative did a 180 degree change in so little time.

What we don't know, is that those results cannot be translated directly on a real world environment. The transmission dynamics are varied, and the way people act with and without masks, makes these kind of studies really just a baseline to the reality.

There has been only ONE single randomized controlled study, in a hospital setting, and it was just comparing strict guidelining with respirators, vs cloth masks and a control group with doctors doing their "usual practices", and what they found is that only respirators with strict guidelines had any difference, the cloth mask group actually performed worse than the control group.

Now, this study isn't really applicable in the general population either, and it isn't good enough to say anything about masks, since the setting was in hospital, it used strict guidelines, and people in the control group weren't necessarily not using masks, but just doing their "usual practices" as medical professionals, even thou one of the conclusions of the study was actually saying that the results showed a combination between the mixed control group and that probably cloth masks could have negative effects.

That's why the Danish study is important, it was basically a complement to the already existing randomized study I just talked about, but instead of looking at a Medical environment, it was looking at the general population, with a control group without masks.

The article you keep mentioning is not published, it should have been at least as a preprint, and excuses about it are not believable

I love how when people hold to an ideology, magically they feel they can just call everyone they disagree with a liar (I mean, you are saying that the fact that they cannot get their paper published, which was covered by Danish news, is just an "excuse", basically saying they are liars) but ok.

If the study gets published, as they actually confirmed that are trying to get it published, will you acknowledge the results?

I know I will, even if it's not what I expect, because the methodology is exactly trying to answer the actual controversy on general usage of masks.

Digging a little bit more, it seems that at least one news paper in Denmark has published today an article about this debacle.

Posted in: Japanese researchers show masks do block coronavirus, but not entirely See in context

Having biorxiv available for preprints this sounds more like a bad excuse than a real reason. Scientists do not depend on journals anymore to let other people know their results, their actual use if (supposedly) a good peer review system and collect IF points to get a better position in the future, but since most journals have no problem accepting papers already made available as a preprint anybody can do both things without problem.

This is a pretty big study, with many authors (14 people, 4 of which are lead researchers), and according with some of the authors, there is disagreement if they should make available the preprint without a journal, but some of them do not want that, as they believe it would undermine the results and they would just be ignored.

Let me be just clear, this quotation if from just one of the authors, as a simple response he gave to people asking why the results have not yet been published, even thou they were supposed to be available in September, but the detailed reasons why this is happening are not known, the only thing that we know is that some of the authors are pissed of at this situation.

You can read the actual methodology and details of the study here, which was published in a journal back in August, which was peer reviewed and accepted by the Danish Medical Journal:

The most frequent reason to avoid publishing something even as a preprint is that the results are not what they wanted to find or the methodologies used to "prove" their conclusions are too obviously flawed.

Once again, this isn't some study made by a single person, or anything like that, they had funding from the Salling Foundations, they methodology is already public, so that also doesn't make much sense.

Not to mention that this study was highly quoted by many reviews and papers who talked about masks, as one of the most important current studies on the field.

In the worst case scenario, they could just do it again, but the response of some of the authors make it seem that is not the case.

Once again, there is no public statement about the situation of what is going on with this study, but, as I said, what we need are exactly studies like this one, instead of these low quality, done a million times science fair experiments that keep finding their way into the national and international news as the "definitive answer" to some problem.

Posted in: Japanese researchers show masks do block coronavirus, but not entirely See in context

This is a controlled environment experiment, which is good as a baseline but it isn't really that good at predicting outcomes at a community transition level.

The results of this study are kind of obvious by themselves, obviously if you have any type of physical barrier you will have to some degree a reduction in particles, but this not the kind of research that is needed right now, since it really doesn't represent the real world.

What is needed right now is a randomized controlled trial that test masks vs no masks.

In fact, there is one already, NCT04337541, which was already completed, but even thou the trial was highly regarded and quoted in the recruiting phase, has been unable to publish their results because, and I paraphrase one of the authors, the journals are afraid of the consequences of publishing the results.

Posted in: Uber Eats Japan offering strange discount just for people who don’t really need Uber Eats See in context

Does that include the costs to operate, buy tires for, maintain, insure and register your car and depreciation on your current car that you put towards the next car when you wear your current car out from all these deliveries?

Are you aware that most people in Japan who do Uber eats do it with bicycles?

Those who I know that do Uber eats with cars, do it as almost a side business while they already work in the transportation industry, so they don't really have to worry much about those costs.

Most of these Uber and Lyft drivers are essentially working for a negative income when you consider the costs incurred by using your vehicle. 

We are not talking about Uber X or Lyft, since "shirotaku" is illegal in Japan, and there is no such thing legally speaking in this country. I have no idea of the rate for those services in other countries, so I cannot really talk about them.

Posted in: Hard hit by virus, airlines push for tests over quarantines See in context

The mandatory quarantines are extremely prohibitive and a deal breaker for anyone traveling unless going to your country of residence.

Not even for people of that country of residence is a good idea.

For example, I've not travelled mainly because of the 2 week quarantine put on Japanese citizens when coming back. I don't live in Tokyo, and in order to get back to Hokkaido I need to use a plane, which I can't after I come back to japan because of the not using public transportation order, so the only solutions I have is either staying in a hotel for 2 weeks in Tokyo, or having my boyfriend drive all the way to Tokyo, and then drive all the way back to Hokkaido.

Nether is a good idea, and makes travel an impossibility.

But the thing is, tests also aren't a solution, because there is always going to be a limited number of tests, no tests will basically put a hard cap on the number of people who can travel, not to mention that in the case of a false positive, which are a thing, people are not just going to be unable to travel, probably lose money, but also have a horrible experience.

People have to come to terms, like they have come with all other transmittable diseases, that fighting against a rapid mutating virus, with a high percentage of people having no symptoms at all, is basically a lost battle.

We are just doing extra damage with all these stupid rules.

I was told Uber Eats pays workers some 200yen per ride. Enough said.

You were told completely wrong.

The average per pick (without incentives, meaning boosts or tips) is about 400yen-500yen if about 1km, or 500yen-700yen if 1-5km.

With incentives, and also depending on the city and requests at the time, you can make way more than minimum wage with Uber Eats.

Posted in: Medical masks best, cotton good, bandanas worse: droplet study See in context

That is not supported by any studies I have seen. Citation would be good.

Which part? The part of asymptomatic people having no symptoms?

Sneeze etiquete stopping droplets? Because each one is kind of self evident.

Here are some recommendations on sneeze etiquete to prevent infections:

Which is no problem, it is not like you can only do one or the other, you can easily do both.

Never said it was a problem.

Citation for this. What is the ID50 for covid-19? how likely is that a reduction of exposure of 90% have no effect in transmission?

The ID50 of SARS-CoV-2 to cause COVID-19 is not known. But usually the ID50 of an infection is more dependent of the viral load of the individual, than the dosage of virus in each droplet.

What I'm saying is from the only available study into cloth masks as a way to stop an infection of ILI.

As said before, there is actually very little studies on the actual effectiveness of masks to stop infections, which for most of the questions you are asking the answer will be "we don't know".

Citation needed for the first part, who demonstrated that a mask does not offer any kind of protection? I mean, absolutely nothing protects to a perfect 100%, but that is not the same as not being protective.

Once again, studies are scarce in the mask front, but basically most randomized high evidence studies find that if there is any benefit on the wearer, it is only with high quality masks.

But there is actually a report from Norway’s Institute for Public Health that made calculations on the current COVID-19 pandemic, and how many infections it could prevent if we assume a 20% asymptomatics and a very large 40% risk reduction by wearing masks, and found out that you will require 200,000 people wearing one to prevent a single infection in a week.

Citation for this would be very interesting, even recent articles only mention that this is considered just a possible route, not even confirmed, much less a "mayor" route.

It would be very interesting to see this evidence, seems like a very simple study to make, and even simpler thing to correct.

So masks are the same as every other preventive measure, from isolation to washing the hands, no surprise here, a perfect reason to educate people in the correct use, not so much to stop recommending doing it.

That wasn't the point I was trying to make.

Anybody that actually would have any trouble by using a 3ply or cottong mask puts more their health at risk by being in any kind of situation where the mask is recommended. The actual recommendation would be not to be in that situation in the first place.

Not really, There are many ailments that have negative consequences by wearing masks, and are not at all vulnerabilities against COVID-19.

One of those groups are those who have medication and behavior managed severe chronic migraines. I know at least of one case of someone like that who has suffered a lot because of the masks requirements, many times not being able to get out of his bed for days with vomiting after wearing a mask for an hour.

Your response is in fact the kind of problems I've seen on this, it is assumed that anyone with a real health problem isn't shouldn't be saying anything for one reason or another.

This should be solved by increasing the supply, there is absolutely nothing wrong with recommending something that is useful and have an effect.

Actually, there was already damage done because of this.

In the UK, people in care homes who had COVID-19 patients were unable to get access to any type of masks, because the government put them in the bottom of the list to get masks, and there were even stories of workers from care-homes asking to school children to make some cloth masks for them, out of desperation.

It is well known that the UK high death toll was in a big part because of there uncontrollable outbreaks in the care homes.

But hindsight is always 20/20 I guess.

Bad would be to recommend something useless, since this is not the case the solution is to have more masks so they can can their intended effect everywhere they are needed.

Not sure if you read the same article, but they basically said that bandanas are useless, and if I remember correctly there were recommendations in some countries of using them.

Which epidemiologist? based on what data? how much of the discussion has been done about the obvious other solutions that solve the problems?

Do you want me to list them all?

I would say, read the discussions and responses on articles like the ones from the BJM.

The people who I know who are "famous" and have been consistently warning about a blanket mask wearing by the wide population , or are critical of these policies are:

Tom Jefferson

Carl Heneghan

Anders Tegnel

Henning Bundgaard

Epidemiological evidence is also science, after all there is no "hard science" proving the quantitative effect of isolation or hand washing for the prevention of COVID-19 either? so according to you there is no point in recommending any measure.

It is not the same. I'm talking about high quality evidence studies against low quality evidence studies.

There is very high quality evidence for isolation, hand washing for the prevention of ILI. The evidence for face masks is extremely lacking.

There are very few mask studies, and most are not even randomized.

-2 ( +1 / -3 )

Posted in: Medical masks best, cotton good, bandanas worse: droplet study See in context

As I've been saying for a while, masks are just supposed to stop coughs and sneezes, and the quality of masks do matter.

Now, the conondrum of all of this is, asymptomatic people, by definition, have no symptoms, which means they are not going to be sneezing and coughing all the time, and I'm the rare occasion they do, sneeze etiquete should be for the most part more than enough to contain droplets.

In fact, even with masks people should engage in sneeze etiquette, since, like this study shows, droplets still fly away even with masks.

Also, even if droplet ammout is reduced in by up to 90% in cloth masks, infection studies have showed that they performed about as good or worse than not wearing a mask, which means that the remaining 10% of droplets is more than enough to generate transmission by droplets.

My worry, and that of many epidemiologists is not about droplets, but about infection dynamics and risks associated.

First, a mask will not protect anyone against infection for the most part, and most studies link SARS-CoV-2 infections to long interactions in closed spaces, making interfamily in-house interactions the main route of infection.

There is strong evidence that orofecal transmission is a mayor route for SARS-CoV-2, which cannot be prevented by a mask.

Second, there is evidence that people who use masks tend to not social distance, and even in cases forces people to get closer in order to hear a muffled voice, which can have a negative effect on transmission.

Third, not using a mask properly, using the same mask for a long time, constantly touching your face to adjust the mask, moisture accumulation in the mask among other factors can make infection more likely than not wearing a mask at all.

Forth, masks recommendations create stigmatization and discrimination for those with conditions that do not allow them to wear masks, who many times are forced to wear them anyway, putting their health at risk.

Fifth, mask recommendations have already created a problems in the supply of masks, which can translate into people who do require masks not being able to get them.

Because of these risks, and the fact that there is very low evidence that masks are working to prevent the most common routes of transmission, some epidemiologist are against blanket usage of masks by the wider population at all times when outside the home.

Most recommendations by epidemiologists involve very specific scenarios, like peak hour public transportation, in which the distance between people is so small that using all methods posible to avoid transmission could make sense, but once again, even for these scenarios, recommendations are based in theoretical prevention, and not in hard science that has proven the prevention.

Not to mention that news that say things like "this has nothing to do with the pandemic" or say anything not approved by the government are dangerous fake news, and in the middle of a pandemic these people should just dissapear in the middle of the night for the safety of all.

It all depends on what "encouraging" means.

If encouraging means something like, manipulating someone emotionally so that they kill themselves, then yes.

If it is something like, a group of persons who are thinking of a group suicide and talking about how the world sucks and life sucks and how killing themselves is the best option, I think it shouldn't be a crime, but it is a very murky situation.

I think intention is crucial in something like this.

It would be nice if Americans living in Japan didn't brought their national politics to this country and tried to politicize a matter that should be for all intent and purposes scientific in nature.

In Japan, discussions about masks are way more civil, and people who have refused to use them, like Horie Takafumi, are allowed to speak their mind without getting bombarded.

Once again, I'm glad I live in Japan in these times.

Covering up isn’t a foreign concept to us here in Japan Luis, cmon, how conceited a comment is that?

I never said Japan, I said for you, because you seem to think that only masks can prevent saliva from sneezes to spread. Not to mention that asymptomatic patients, which are supposedly the whole reason of this thing, are not going to be sneezing like a symptomatic patient.

But none of this really matters, you says it works because it is since, not providing any argumentation, and I just should say that you are right.

Having a physical barrier between your face is so logically and painfully obvious to most.

Then wear a face shield. That is way more of a physical barrier and without micro openings like masks.

Masks are effective. It’s science bro

With arguments as strong like that I really wish I didn't spent all that time writing arguments for my position.

If Masks were meaningless in stopping droplets they would not be worn by medical professionals.

I think I myself addressed this point.

For maintaining sterile environments they work. Surgical masks are the only ones, with low evidence thou, that have shown to have any effect with viral infections.

Cloth masks, which is what most people wear in Japan, if anything have been shown to be useless by the scientific literature, with the possibility of being worse than wearing no mask at all.

Before corona, the main reason why people wear masks was to stop pollen, which those masks actually can do.

And since you will still refute that, how about I sneeze near you twice?

Once with a mask, once without. And after that, you can get all scientific and argumentative again.

I present to you the probably foreign concept of "covering your mouth, and looking down when you sneeze".

In some parts of the world before the Corona scare this was though as simple hygiene and common sense.

If done properly, it is more efficient at stopping droplets from going out wild from your mouth, which is why it is recommended even for people wearing a mask.

Posted in: Are you OK with wearing a mask when you are out and about as a measure to protect yourself against the coronavirus? See in context

And to reply to Luis, I don't know which literature are you reading but you should change your sources because you are completely wrong. Surgical Mask reduce the infection rate. They are not 100% efficient, but reduce the contamination of other by more than 90% and protect yourself at around 30%. And if you want to protect yourself better you still can with FFP2 mask that protect you at a rate that is higher than 80%.

Once again, citation needed. I've been reading mostly evidence reviews, some by the Centre for Evidence-Based Medicine of Oxford University, others by the Sax Institute for the Australian Commission on Safety and Quality in Health Care, among others.

And they point to all the relevant studies in their review of the evidence.

Most mask tests that have been done (which aren't that many in the first place) have been done on a medical environment, many aren't even randomized, and many their control group sucks (like the only peer reviewed test on cloth masks, in which the control group was a mixture between people without masks and people with masks, without even taking into account the type of mask or anything).

The only reviews that I've seen that have anything positive to say about mask usage are mostly political in nature, and are trying to give "recommendations" to the government, instead of doing a plain scientific review of the evidence, and their recommendations are basically based in "they might work, so we should use them" ignoring the low evidence for this.

I would ask you, were do you get your info from?, is it a single source, or do you actually look for multiple papers on the literature, and take into account the quality of the evidence they provide?

Because that's what I do.

There many studies that say that transmission (mask to mask) are almost inexistent.

Citation needed.

Masks also lower the viral load you would get, even if you are infected. 

Citation needed.

Those are real studies that say that mask efficiely reduce droplet. And droplets is the main transmission factor in this case.

Masks do stop droplets, but this ignores 2 big points:

if someone is asymptomatic they will not generate to many droplets. Mask usage as a method of stopping droplets is mostly done to avoid contamination of an sterile environment, in the case of people with flu like symptoms, to stop droplets from sneezes and coughs

if we are talking about asymptomatic patients, a review on the evidence shows that asymptomatic patients are not seen as the main carriers of the virus, nor as the main sources of the spread.

The actual transmission dynamics on asymptomatic patients are controversial, specially because the definition of an asymptomatic patient is kind of all over the place. If we see an asymptomatic patient as someone who shows positive in a PCR test but doesn't show any symptoms doesn't really, right now it gets counted as a confirmed infection, but the truth of the matter is, PCR tests cannot confirm infections, just if material from the virus was present.

There is actually controversy over the fact that it seems that many of the people who are getting positive results of a PCR were infected but no longer are (meaning, the PCR test shows material of the virus, but the virus is no longer active or able to replicate AKA death), or people who were in contact with the virus but have not actually being infected by it.

So what actually constitutes an asymptomatic patient is not really cristal clear. There are some who are said to be asymptomatic because they show positive in the test, but end up showing symptoms, and they get called "pre-symptomatic".

A review of the evidence has shown that these "pre-symptomatic" are responsible for most of the so called asymptomatic transmissions, and that asymptomatic transmissions are actually quite rare.

What you are saying is basically a theory that, since masks stop droplets it should be effective against SARS-CoV-2, assuming the main transmissions method of SARS-CoV-2 is by droplets, but you require an actual randomized test to be sure about that theory. There isn't one, and since people didn't even cared about coronaviruses before, most of the literature in this respect is mostly based on influenza viruses, which doesn't always translate well with coronaviruses.

Posted in: Are you OK with wearing a mask when you are out and about as a measure to protect yourself against the coronavirus? See in context

If you’re not wearing a mask during a global pandemic, you are ignorant, selfish or both. Period. Full stop.

Did you wear a mask in the previous 2009-2010 H1N1 global pandemic?

Posted in: Are you OK with wearing a mask when you are out and about as a measure to protect yourself against the coronavirus? See in context

You're a higher risk of catching Covid-19 by not wearing a mask.

Also citation needed for that one.

I've reviewed the literature, and if anything, even thou there is low evidence, if you used a surgical mask properly there is a chance that if you have the virus, the probability of you passing it to others will decrease, not the other way around.

I've seen studies that used surgical masks to try to prevent those using the masks to get infected, and they never found any real reduction to the rate of infection.

If you're a serious case, the costs of your care will be very high, and you're now a burden to rest of us.

Same thing for any other transmissible illness, but people do not seem to care about any other illness, yet, I've never seen this argument for any other transmissible illness.

Also, if anything, this makes a good case for allowing private healthcare in this country. If governments are going to control my life based on things like healthcare costs because we are forced to use a socialized health care system with no alternative, I would like to opt out of that system.

What if you don't wear a mask and you're wrong? What if you wear a mask and you're wrong? One hurts you and others. The other doesn't hurt at all.

Actually, one of the reasons I personally don't use one is because there are possible harms associated to mask wearing. There is evidence that people who wear masks feel safer and stop taking other more relevant measures, if what you care is about virus transmission.

Mask usage muffles the human voice, which means that people have to be closer in order to hear each other, and this is specially worrying for the elderly, which many of them have already low hearing.

Mask usage, if not used properly, can actually cause a higher infection rate, because of things like constantly touching your face, accumulation of moisture in long term usage, among other reasons.

Here is the thing, unlike you, I'm not going to tell you what to do. If you think you should use a mask, then go ahead and use one, I mean, I might think it is unnecessary, but I'm not the one to tell you that.

Not to mention, I'm not going to try to guilt trip you with a "What if you are wrong?" scenario, in which I can blame you for higher infection rates, and other mask wearing related harm possibilities.

And that's the thing that most angers me about this discussion, it is a assume benefits ignore risks absolutist discussion, in which basically being skeptical about measures that have yet to be proved efficient, and in the first place necessary, for many mask radicals is almost like heresy.

It's really painful to see people being so smug and self righteous about something that, once again, doesn't even has hard evidence, but still try to paint anyone who for any reason is not in favor of a blanket mask wearing policy as, like you said, "not logical", and worse insults.

If people were really worried about transmission, then they would stay at home. But what I see is that masks are more like a replacement for the stay at home policy, with the hope that it will be just as or more effective.

Masks, even if they do work, are not going to completely prevent infections, just reduce them, and the amount that gets reduced, from the low evidence studies on the subject, is not really that significant, specially when you have a widespread virus that is not going to go anywhere any time soon.

A policy like this MIGHT have had some point very early when the virus was discovered, to prevent as much as possible spread, in order to make the virus disappear. It is too late for that, and people need to be realistic and stop thinking that we are going to be able to make this virus disappear. It is not going to happen, this virus is here to stay.
