The new normal

A month is a long time, an advert on the February 27th Naked Scientists podcast was run by the Local Enterprise Office here in Ireland for “Local Enterprise Week” at the beginning of March to “help local business grow in 2020”. I wonder will people become wary of meeting others after this pandemic is over? I’m slowly catching up on my podcast backlog. Many are being recorded at home or even on a park bench as happened with the March 16th episode of Planet Money.

Schools in Ireland closed on March 12th, so we’ve been at home since then. New restrictions were introduced on March 27th, as summarised by Gavin Sheridan:

Irish Taoiseach Leo Varadkar has announced:

1. For two weeks, to April 12, everyone to stay at home in all circumstances (except essential services, shopping, medicines, care for relatives, brief exercise)
2. All public and private gatherings of any number of people banned.
3. All non-essential shops closed.
4. All community centres closed.
5. Shielding introduced to all over 70s.
6. All visits to offshore islands banned.
7. No travel outside of 2km of your home (except reasons above), for any reason.

New restrictions announced

It has made a noticeable difference. I haven’t left Blarney since then. Even before that I had curtailed how much I walk but now it’s a quick walk around the park with the dog in the morning and evening. Pokemon Go gyms have been relatively stable. There’s one by the River Martin that hadn’t been attacked for over 100 days until mid-March but because more people were staying “close by” they were walking down there. That has stopped now and the gym hasn’t been touched in 7 days.

Google Fit knows I’m not going anywhere

Blarney Woollen Mills is blocked off, but you could still get in to the grounds there if you hopped over a low wall. One of the gyms in there remains untouched after 15 days!

Blarney Castle Garden was open until a few days ago, but the new restrictions closed them.

Dave Bolger created a site called 2kmfromhome.com where you can find out how far you can exercise. Simply launch it on your phone and allow it access to your location. It will then display a map around you with a circle where you can go.

Work on the construction site across the road from my home has ground to a halt which we’re grateful for. The road outside is still clogged with dust and of course they never clean it up properly.

PPE, Personal Protective Equipment, is a phrase that has entered everyday language. Every country has shortages of it but Aer Lingus are flying to China to pick up PPE worth millions of Euro.

If I remember correctly the Government expects to buy €225 million of it over the next months. Unfortunately the latest flight had to return and make an emergency landing after a bird strike.

People are queuing outside shops because the stores have limited how many people are allowed in at one time. Going shopping is stressful. People jump back from you if you get too close. This thread on Reddit compares it to a survival game.

Last Week Tonight was filmed at home. Other American talk shows are too. Ryan Tubridy presented a couple of episodes of The Late Late Show without a studio audience but a few days ago it was reported he had tested positive for Covid-19. Miriam O’Callaghan took over last week’s show. Irish radio shows are being recorded at home. My wife rang the bank this morning. The woman she spoke to is working from home and thought it was weird. She’ll get used to it.

Chris Hadfield offered advice for people staying at home

In a sure sign that people are getting used to this new normal some on Twitter were worried that bots were congratulating and supporting the government on everything they do. I somehow doubt that’s happening and others have pointed out that it’s really hard to get a Twitter username without trailing numbers unless you come up with something unusual. I bet there are a whole lot of new Twitter users now looking for the latest news.

Concern that Twitter bots are supporting the government.

Fine Gael are no saints and they’ve made lots of mistakes in the past but they deserve our support at this time.

Even Jim Corr, he who fights the New World Order and the evils of 5G had choice words for Paddy Cosgrave who is repeating all sorts of nonsense and lies. Quite a moment.

There are two many cases where people have spat at Gardai and told them they are infected. A father and son in Cork did this and were arrested. A woman in Dublin did the same.

I saw on Twitter this morning that a 13 year old boy died of Covid-19 in London. Heartbreaking. 🙁

If you have a few minutes write a letter to Andrew McGinley. In January he found his 3 children dead in the family home. His wife was found nearby and has been charged with their murders. Andrew is feeling the effects of isolation.

He is getting lots of post but this one just breaks my heart.

Amidst all that WordPress 5.4 was released. Yay!

I love the header image on r/Ireland.
I love these Zoom backgrounds.

FYI – the first case of Covid-19 in Northern Ireland was reported in late February, with the first case in the Republic two days later on February 29th.

News from Italy is still dire but they seem to be slowly flattening the curve there. 17 more died in Ireland yesterday from the virus. 🙁

Making Plans for the Weekend

You’ve probably seen this one already:

Or it might look like this:

I was going to write a post featuring that image because Taoiseach Leo Varadkar announced yesterday that everyone in the Republic of Ireland must stay at home with very few exceptions in an attempt to stop COVID-19. There’s an increased Garda presence with motorists likely to be stopped and asked where they’re going. Exercise must be taken within 2km of home.

The image used in the meme above isn’t great. Every time I saw it the floor plan was blurry while the text was pin sharp so I wanted to know if there’s a better version available.

Looking for that image I think I found the first or perhaps very early use of it on Reddit.

That image is a paltry 360×360 pixel image, without the headline text. It seems at least two different people created memes out of that tiny image and it went viral!

There’s a global pandemic in multiple countries and people are creating memes. This letter from Italy is right.

You’ll laugh. You’ll laugh a lot. You’ll flaunt a gallows humour you never had before. Even people who’ve always taken everything dead seriously will contemplate the absurdity of life, of the universe and of it all.

Edit a bit later: Gardai are stopping traffic as seen in this video. They’re talking to the driver through the passenger window. Via this tweet.

The facts of food

Alternative facts have long existed in the world of food. When you create a powerful enough fiction, you are no longer bound by the need for evidence, for fact checking, for responsibility and a concern for the safety of the vulnerable. The people peddling the candida myth have discovered that in making up a problem, valuable new markets can be created from nothing.

I always thought flossing was good for my teeth

This SBM article leads me to question the idea that flossing my teeth helps to prevent dental cavities and gum disease.

It’s more complicated than that.

Done “by professionals” it can reduce dental caries (tooth decay) but if you’re not flossing at least five times a week there’s little benefit to it. Maybe the professionals had a technique the rest of us don’t know, or perhaps they were more diligent about flossing during those trials. Who knows?

To floss, or not to floss? That is the question. Now that you are armed with the evidence, you can make the choice which is best for you. If you want to prevent tooth decay, you should focus on reducing your sugar intake, use a fluoridated toothpaste, and perhaps a fluoride mouth rinse. Whether you decide to floss or not depends on your desired outcome. For a fresh, debris-free mouth, yes, go ahead and floss away. If your desire is to prevent cavities or periodontitis, other methods are more effective.

Many years ago before I started flossing regularly I rushed to the dentist while on holiday with a terrible pain in my mouth. Fearing that a tooth would have to be pulled or cavity filled I sat in the chair, leaned back and the dentist took one look. He grabbed some floss and removed the crumb that had lodged between my teeth. The pain was gone!

So, just like the author of that article, Grant Ritchey, I’ll continue to floss every night. There’s no downside and my mouth feels better for it, even if the science doesn’t fully back me up on this.

Why the hell is sitting so bad for us?

The numbers are scary. Sitting really seems to be bad if the observational studies and meta analysis studies are to be believed. Sitting for lengthy periods of time contributes to all sorts of nasty diseases like cancers and heart disease. It’s a wonder I’ve reached this age at all!

It doesn’t matter how much you exercise, it has no effect on how bad sitting is for you. You’re better off getting up and walking around for 2 minutes every half hour or hour than doing that intensive hour of walking in the morning. (damn)

And the findings were sobering: Every single hour of television watched after the age of 25 reduces the viewer’s life expectancy by 21.8 minutes.

By comparison, smoking a single cigarette reduces life expectancy by about 11 minutes, the authors said.

Looking more broadly, they concluded that an adult who spends an average of six hours a day watching TV over the course of a lifetime can expect to live 4.8 years fewer than a person who does not watch TV.

Get Up. Get Out. Don’t Sit.

I’m just glad I have a standing desk but I need to use it more often in it’s elevated position.

I have no idea why sitting is bad for you. The video above suggests a few reasons but it’s all speculation.

Why Is Fluoride Good for Teeth?

It’s well known that fluoride is good for teeth, that it stops or slows down tooth decay. How does it do that? This video explains the process by which fluorapatite is formed and remineralises the teeth. For a more detailed look, there’s also this technical article I found that’s worth getting your teeth into digesting. 🙂

The hydroxyapatite of tooth enamel is primarily composed of phosphate ions (PO43–) and calcium ions (Ca2+). Under normal conditions, there is a stable equilibrium between the calcium and phosphate ions in saliva and the crystalline hydroxyapatite that comprises 96% of tooth enamel. When the pH drops below a critical level (5.5 for enamel, and 6.2 for dentin), it causes the dissolution of tooth mineral (hydroxyapatite) in a process called demineralization. When the pH is elevated by the natural buffer capacity of saliva, mineral gets reincorporated into the tooth through the process of remineralization.

When fluoride is present in oral fluids (i.e., saliva), fluorapatite, rather than hydroxyapatite, forms during the remineralization process. Fluoride ions (F–) replace hydroxyl groups (OH–) in the formation of the apatite crystal lattice (Figure 3). In fact, the presence of fluoride increases the rate of remineralization.

Fluorapatite is inherently less soluble than hydroxyapatite, even under acidic conditions. When hydroxyapatite dissolves under cariogenic (acidic) conditions, if fluoride is present, then fluorapatite will form. Because fluorapatite is less soluble than hydroxyapatite, it is also more resistant to subsequent demineralization when acid challenged.

There’s more sugar in skim milk

If sugar is the new bad guy, taking over from fat, should we drink skim milk?

If you take out the fat, everything left behind is more concentrated, so you get marginally more sugar per volume of liquid. I guess it really matters if you’re consuming liters and liters of milk per day but it probably won’t make much of a difference to your porridge and a few cups of tea.
