True to form ....Yet another 'subtle' personal dig.

And yet you are unable to rebut my logical responses and explain why my actions increase the threat to others . I am wearing a mask. That is what the rules state I should. Besides I do not live in the UK as you well know and ironically in a country that now has a very low infection rate in a region with one of the lowest rates in the country. People here take a generally cautious but pragmatic approach as do I.

 

Actually it IS! I used to go scuba diving and since the Demand valve in your mouth is your sole source of air and you inhale and exhale through it for anything up to 45 minutes and no air escapes through your nose then it is easy to do the same for the few seconds I am talking about .

The criticism of me on here from the usual suspects is more about me than the content - I dont know more about science than scientists but no one has given me a reason why my approach to using the mask is wrong...
Those doing so on here seem to be those who follow the mantra " you don't need common sense when you have rules"

Go on then a) tell me that all people in UK are following the rules and b) how my approach endangers others.

 

Wow just wow

 

Go on then explain?

 

Ok it means you constantly have to readjust the mask meaning you spread the germs all over your face and all over your hands. Its act extremely hard not to breathe using your nose at all.cyou !at think you have somehow sealed off your nose but you haven't.
And why does uncovering your nose actually help you at all?

"It doesn't specify how I have to wear it".

You know what. I don't like wearing them. They're extremely uncomfortable for me. I don't think they help as they make people complacent. But guess what. I wear it properly and don't try to find loopholes and technicalities to get round it because I'm not a selfish ****.

 

You don't have any logical responses, that's why. You are making your own rules up to suit because you know better, as per usual.

Tell you what, breathe from your mouth for a couple of mins and lightly press your fingers against your nostrils and then tell me your nostrils don't flare at all. You'll be lying if you do.

 

I am fully aware of the reasons for covering the nose as well as the face and have mitigated those. Furthermore They are not loopholes or technicalities and I do fully cover up when in close proximity to others . Furthermore we actually limit our contact to others which is the best way to prevent spread in any case so as regards being a selfish **** it is not me being being holier than thou.
Furthermore they are more than just "uncomfortable" here but genuinely impossible for me to wear for extended periods without taking some action short of removing it on certain days throughout summer. Te alking to some staff in our local supermarket they have all said they do the same at times.
The guidance from many experts does indeed state that you should cover nose and mouth (obviously breathing normally involves air) passing through both mouth and nose (mainly nose), I know that, but it does ALSO state that there may be times when you have to remove it or lower it but should try to maintain social distancing when doing so. (which except on rare occasions which I outlined we do)
I know one or two have issue with my political views and attitudes so seek to take personal digs at every opportunity but 9 times out of 10 fail to come up with rebuttals to my PoV choosing instead to make inane comments.

 

Not lying. Apparently you always claim to know better so 'pot....kettle' Its opinions not fact.

In any case, who said anything about a couple of minutes. Like I said, you are over emphasising and misintepreting what I have said. It is only for seconds and the other times i lower the mask is when nowhere near others. Also as for my "lack of logical responses" I KNOW I can breath without expelling air from my nose (if you have ever scuba dived, the facemask covers the nose and eyes and creates a watertight seal. The only time you breath through the nose is to equalise the pressure so the mask is not pressed to hard against the face. If air was being expelled through the nose you would be leaking it around the mask seal and also steaming the mask up constantly which does not happen. There! ... a logical response for you and evidence to rebut your argument !

It appears that people a handful of the usual suspects including yourself cannot allow some people who they have issues with express opinions on here without jumping in and turning it into a personal witch hunt.

You know you can avoid breathing through your nose in a situation where there is pressure preventing it. That is not at all analogous to a situation where there is nothing preventing you breathing through your nose and it can happen accidentally or at the same time as breathing through your mouth.

 

Huh... getting silly now trying to rationalise your objection. You are actually talking nonsense....

Firstly air pressure is equal to around 14.7 p.s.i .at sea level (hardly "nothing preventing you breathing through your nose")

In actual fact if you really understand physics and know anything about diving you'd realise that when you dive you equalise pressure meaning the air pressure in your lungs equals the external pressure which is how demand valves work. The differential in increased pressure over seal level decreases every 10 metres of depth. As an aside If you are wearing a dry suit you have to add air the deeper you go to avoid suit squeeze. Your lungs therefore contain air at the equivalent pressure to the water surrounding you. If it didn't you would not be able to inhale and exhale.Your body therefore absorbs into the bloodstream excessive nitrogen that you have to get rid of by ascending slowly ( and depending how deep you go and how long you spend ) may have to hang about at depth (around 10 metres) decompressing so as to avoid the bends bubbles forming in the circulatory system. It is also why on an emergency ascent (likely to cause narcosis (bends) you exhale all the way up (qe were taught to shout Shiiii-iiittt!!!! all the way to the surface. If you held your breath your lungs would literally burst.

Open water diving requires quite a lot of theory and study ...e.g. Boyles Law, physiology and effects of nitrogen absorption. Dive tables are essential or if lazy like I was a dive computer that works out decompression timings etc between dives.

 

I'm not talking nonsense. I have a pretty good understanding of physics and have scuba dived myself, but thanks for the condescension and the ramblings on points which aren't relevant to the point I was making.

The mask is pressed and sealed to your face. In order to exhale through your nose you have to do it with enough strength to overcome the seal, which you won't do without deliberate effort. You aren't consciously attempting to not breathe through your nose, you're just not consciously attempting to breathe through your nose.

This is entirely different to on land where you can quite easily breathe through your nose without realising even if you think you're only breathing through your mouth.

 

@Tekkytyke The reason you feel better when lowering your mask below your nose is because you are breathing through it without realising. One inch of skin (which is all it is if it is not functioning as a nose) being exposed isn’t that much of a relief and if it is, why not just lift the bottom higher and have an extra inch of chin out instead? Or just have it over your nose and close your mouth? You don’t do those because you realise it’s stupid but can’t seem to see that what you are doing is just as daft.

 

That is the elastic strap pressure you are overcoming NOT the external water pressure. The same would apply if you wore it on land. If you removed the strap the mask would fall off because the internal pressure equals the external pressure. Even if a tiny amount of air leaks from the nostrils that is not sufficient to project any more droplets any distance than the leakage you get around a mask. Probably less so given masks are not airtight and expelling air on exhale forces air out through and imperfect seal at around the mass. Venturi effect increases the pressure and so speed due to the constricted opening.

As regards being accused of ignoring experts are they the same who first said masks were essential then they were not then they were then two metre distance was adequate then micro droplets were airborne for hours so several metres were required.

 

OK, pressure was the wrong word to use but the point stands.

 

And people accuse ME of being patronising. I am capable of holding my breath and also knowing when I am breathing though my mouth. You also miss the point that unless someone is close I AM breathing through my nose and only breath momentarily through my mouth or hold my breath if I am forced to pass someone within two metres. The inhalation of (relatively) cool air is not a placebo effect. It is real. Our shopping is done at quiet times and means we are usually in the shop with only a handful of shoppers. It is easy to avoid people . Obviously at checkout the mask is worn appropriately. This whole thread has got out of hand .
