If you only have time for a few snippets, this warmed my heart:
‘I left that day with a full heart thanks to all the “thank yous” and “I love yous” from the residents. We were invited into many homes, and even offered tea and coffee. I went into a few rooms with elderly, frail people and young children (this was optional and only if we felt safe). We felt like guests. ‘
Near the end the nurse writes:
‘I have so many wonderful memories of the past few days, all positive. I’d like the broader community to understand that sometimes media portrayals of what goes on are not necessarily true.’
For a very long time now, I’ve noticed that 9 out of 10 news stories are about people who are not infected by the virus ‘doing it tough’. I don’t deny that a lot of people are doing it tough; a massive drop in weekly income will do that to you. But where are the stories about our local heroes? The doctors and nurses and paramedics and yes, police officers who are risking their own lives to keep everyone safe?
And how about the heroes who keep our cities alive? The jobs they do are poorly paid but vital. Can you imagine what would happen if our rubbish were not collected? Or if the power went off and there was no one there to turn it back on again? Or how about food? It doesn’t just appear magically in supermarkets.
We owe every one of these heroes a huge vote of thanks, yet the media ignores them.
And last but not least there are those who have been infected. Why aren’t we hearing their stories? I’ve heard one story about a 23 year old man with Type I diabetes. He came down with Covid-19 and survived, but it wasn’t fun, not be a long, long stretch of the imagination.
If governments want us to co-operate then we need to be told the full story, the good, the sad, and the scary, not just the stories that confirm that life is not ‘fun’ at the moment. If we are to have any kind of life during this pandemic, we all need to rediscover what it means to be socially responsible. We all have to become heroes.
The first part of this video is a little bit technical, but don’t be put off by all the scientific names. Keep watching and you’ll learn why Vitamin D may be useful against our favourite virus. You’ll also learn about its importance for other conditions, such as osteoporosis. I most definitely did not know that.
The thing I found most interesting was the explanation about why people in different geographic locations may be Vitamin D deficient. Apparently, it’s all due to the season, the angle of the sun as it hits the earth, and a country’s distance from the equator.
The video talks about the USA, but I was interested in Australia, so I went looking for a map of the world showing the equator. Then I copied the area from the equator to roughly the middle of the USA. This was the distance from the equator that gets sufficient Vitamin D in summer and winter.
Next, I placed the copy next to Australia. This is what it looks like:
Zooming in on my home town of Melbourne, we get this:
I drew the green line across from the subset map to see if Melbourne does, in fact, fall within the area that receives enough Vitamin D in winter. It does, but only just, and Tasmania seems to miss out entirely.
So yes, we all need Vitamin D, for a variety of health reasons, but no, not all of us can get it from the sun during winter. And if we go from house to car to office and back again, then there’s a good chance we won’t be getting enough Vitamin D, even in summer.
If Covid-19 has taught us anything, apart from how to bake bread, it’s that we can’t rely on technology to save us from everything. Sometimes, living an old fashioned, healthy lifestyle really is the best medicine.
Like many Melbournians, I was immensely relieved to hear that the Grand Prix had been cancelled due to Covid-19, but I was puzzled, and angered, by the Federal government’s continuing mixed messages about the virus. On the one hand Scott Morrison says the authorities will put social distancing interventions in place, but not until Monday [March 16, 2020]. And they won’t apply to schools, universities and public transport.
Why give the virus a whole weekend to turn up at the ‘footy’ and in churches and concert halls and theatres etc etc etc.
If these interventions are meant to stop the rapid spread of the virus, why wait?
Why encourage people to ‘go to the footy?’ And why not close schools, universities and public transport?
Is the delay all about the money?
Despite my cynical anger, there was something about all of this that simply did not add up, especially as the Premiers of all states and territories appear to be in agreement with #ScottyFromMarketing. As my state, Victoria, has a Labor government, I would have expected the Premier, Daniel Andrews, to be more caring of people’s lives than old Scomo.
It was at this point that I remembered an episode of The Drum I had watched just a few days ago [the 12th of March, 2020]. On this episode, the panel of The Drum included a guest, Professor James McCaw, a mathematical biologist and Infectious Diseases Epidemiologist from Melbourne University. Apparently, Prof. McCaw and his colleagues have been modelling the spread of the Covid-19 virus and have been advising the Federal government.
Keep that point in mind, ‘advising the Federal government’.
During the course of the discussion, the panel talked about interventions such as forced social distancing – e.g. cancelling the Grand Prix – as a way to avoid getting the virus and jet propelling it through the community.
To explain the reasoning behind social distancing, they displayed this graph:
Those of you who have been following the Covid-19 virus online will be familiar with graphs that look very similar. The sharp peak is what happens if the virus is allowed to spread without interventions. The flattened, ‘fat’ curve is what happens when you slow the spread of the virus via interventions. The important thing to note from this graph is that a slow spread allows hospitals to cope with the influx of desperately ill people infected with Covid-19.
So far so good. But if interventions slow the virus, and slowing the virus is good, why would mathematical biologists and infectious disease epidemiologists have to model anything? Isn’t it obvious?
Going back to Professor McCaw, I think I’ve found the answer, or at least understood it. This is what the Professor had to say about the virus and interventions:
“The really important thing to be aware of, though, is by avoiding that transmission [i.e. of the virus] all of the people who may otherwise have gotten ill, they are all still susceptible. So as society returns to normal…the population is still equally susceptible, and this is where the mathematicians have a role to play.”
ABC, The Drum, March 12, 2020, at minute 19:55
You can find that episode of The Drum on iView If the link doesn’t take you to the right episode, look for the episode aired on March the 12th, 2020.
So, what exactly does all that mean?
I am no expert so my reading of Professor McCaw’s comment may be completely wrong, but this is how I finally understood it:
the whole world is going to get this virus sooner or later, so…
if Australia stops the virus from spreading, we’ll simply postpone the deaths until a later,
but if a lot of the most healthy people get the virus, they are likely to get only a mild version that does not need hospitalisation.
this will leave the hospitals free to deal with those who do get very sick,
so it makes logical sense to allow this younger, healthy group to get sick, recover and become immune before interventions are put in place,
then, once this first pass of the virus is over, and a vaccine is available, the uninfected members of the population can be protected as well.
From a theoretical perspective, this ‘strategy’, if that’s what it is, would stagger the victims of the virus, making the epidemic manageable. I guess it would also have less of an impact on the economy.
But even in theory, this strategy can only work if the authorities actually know how many cases of Covid-19 there are in the community so they know when to apply the breaks via more draconian interventions. It also assumes that everything else needed to apply the breaks is already in place, ready to go.
Given the lack of widespread testing, I don’t think the authorities do know. I think they are guessing on the basis of how quickly the virus has spread in other countries and extrapolating that to Australia.
More worrying still is the lack of clear, public messaging. People are getting their information from social media, and they’re scared and confused. Getting them to go along with drastic social interventions ‘when the time is right’ can only succeed if everyone understands and agrees with those interventions.
Australia is not a ‘command and control’ country. How are the authorities going to enforce these interventions? Using the police? The armed forces?
People working in the GIG economy, the underemployed and those who think they are immortal will continue doing what they think they need to do for themselves.
This is human nature. Expecting people to behave like robots may work on paper; it will not work in the real world. In the real world, individuals who ignore the interventions could easily infect far more people than the ‘strategy’ anticipates. This will skew the timing and effectiveness of the interventions so when they finally do come, they may not work at all. Or they may not work well enough, allowing the curve of the graph to continue shooting up like a rocket.
But practical considerations aside, nowhere in this strategy is there a recognition of all those who will become collateral damage, the ones who will catch the virus, get sick and die.
According to the statistics, children under the age of 10 don’t die of this virus, but those over the age of 10 do start to die. It’s a small percentage, but it exists:
So who are these children and teens likely to be?
Right from the start, we’ve been told that people with pre-existing conditions will be most vulnerable to the virus. Well guess what, children and teens have pre-existing conditions too. They have asthma, diabetes, multiple sclerosis, cystic fibrosis, Crohns, ulcerative colitis, leukemia, cancers of all sorts… the list goes on and on and on.
What part of the strategy protects these vulnerable young people when they go to school or university or travel by public transport?
And then there are the older age groups. As we age, almost all of us develop some type of chronic disease. I’m pretty fit and healthy, but I’ve had cancer. If the virus gets out of control and the hospitals can’t cope, will I be triaged to die because I am less likely to survive than someone younger?
That kind of soul destroying triage is already happening in Italy.
And what of remote Indigenous communities? They are already behind the eight ball when it comes to health. How are they going to survive when they are often hundreds of miles from the nearest doctor let alone hospital?
We are people, not numbers, yet the silence about us has been deafening. Self isolation is fine, but where are the systems that will make it effective?
I went to Coles [supermarket] this morning. I arrived at 7am, thinking I’d be almost alone in the store. Thank god I was wearing my mask because there was a conga line waiting outside the entrance. What were they all waiting for? Toilet paper.
Coles is now doling the toilet paper out, one packet at a time, but to get a packet you have to stand in a queue next to people who may already be infected but not showing any symptoms.
Toilet paper aside, whole families packed the aisles of the store, stocking up, and every single cash register was open and working at a feverish pace. Instead of being in and out in ten minutes, it took me an hour and a half to get my shopping and leave. The whole time I stood there, flanked by overflowing shopping trolleys, I was acutely aware of the people around me. I didn’t hear any sneezing, but someone did cough behind me. Just a little cough… Probably just clearing their throat… 😦
Professor McCaw’s models may work on paper, but as they are currently being implemented, they are ensuring that the most vulnerable in our society pay the price if things go horribly wrong.
One of the first things I read this morning was that the WHO have finally declared Covid-19 to be a pandemic. It’s hardly a surprise, and yet the news sent a sick shiver down my spine. I only hope that authorities all over the world finally throw away their rose coloured glasses and put their countries on a war footing.
What does that mean?
I hope it means that governments close borders, stop public events, restrict public transport, set up drive through testing stations, and triage industry so that everyone gets the necessities of life, like toilet paper. Beyond that, I hope they force industry to change production, where possible, so that critical medical supplies and equipment take priority.
Why? Because we will not be able to source these critical supplies from overseas, not once the virus really starts to bite. Sadly, we are about to learn that self-sufficiency is more important than global trade agreements.
Will it be possible to become ‘self sufficient’ in the critical things?
Maybe. I have no idea whether local companies have the capacity to build hundreds of new ventilators, but at the very least, we need to have people capable of repairing them if need be. And those people should become critical resources in their own right.
Ditto food production and transport.
Ditto food delivery to beleaguered households.
Ditto medical supplies, not just for hospitals, but for people with chronic illnesses. If they can’t get their prescriptions filled, many will die.
Ditto delivery of prescriptions.
And on and on and on. I don’t know enough about how to run a city much less a country, but someone must, and that someone or someones have to put procedures in place to deal with the logistics of supplying a country in lockdown.
Will it happen?
I don’t think so, not yet. From statements put out by state and federal governments here in Australia, it seems that most are still trying to juggle health vs the economy. An example of this is the Andrews government’s decision to allow the Grand Prix to go ahead in Melbourne. We’ve heard on the news that members of the Renault, McLaren and Haas teams have been put into self-isolation while awaiting test results. Yet the government and organisers are still saying the race will go ahead…with spectators.
Why can’t we be sensible like Bahrain and ban spectators? Or be like China and postpone the Grand Prix altogether?
Covid-19 is already loose in Melbourne. The latest victim is a teacher at Carey, a prestigious private school, who tested positive despite NOT having travelled or knowingly interacted with someone who has. That means the virus is already in the community.
I very much fear that shutting the economy down will cost less, in the long run, than letting this virus rampage through the community at the speed of light. Have a look at this graph from Dr John:
The labels are mine in case you don’t want to watch the whole video [which is here]. In Italy, the authorities were taken by surprise and the virus pretty much spread unchecked before they even realised they had a problem. That is basically the red line. The North Italian hospitals are only treating the most severe patients and they are still not coping. Translate that into people dying because there are not enough beds, ventilators and staff to keep them alive.
The blue line on the graph is what happens when governments stop people from congregating and spreading the virus. There are still infections and sick people in hospitals, but the hospitals can cope and the fatality rate goes waaaaay down.
Oh, and by the way, all those who think that Covid-19 will only kill off the ‘old and sick’, think again. The latest figures from Italy show that the median age is now 65.
Median does not mean ‘average’. Median means the middle point in a long line stretching from youngest to oldest. Or, to put it in really simple terms, there are now as many people under 65 dying of Covid-19 as above 65. Think about that.
You should also think about the positive side of this equation. The ‘draconian’ measures enforced by China to stop the spread of Covid-19 are working. The rate of new infections is slowing. That means China is coming out of the sharp red spike on the graph. Their situation is improving.
Here in Australia we are still in denial, and every day of ‘business as usual’ and ‘let’s protect the economy’ pushes us closer to the Italian nightmare.
My thanks to Don Charisma for posting the latest Dr John Campbell health video on his blog.
For those who haven’t yet heard of Dr John, he’s a retired UK nurse/teacher/researcher who is analysing the latest data about this virus and explaining it to us. He has a Youtube channel, and this is his latest video:
I strongly recommend watching the entire video because it is full of information relevant to different countries, but here are the bits of particular interest to me.
Confined spaces and aircon
There was some meticulous research done [in China] on the spread of infection in a bus. I don’t know what it is about the air conditioning in the bus, but it basically doubled the radius of infection to 4.5 metres. In simple terms, the virus from an infected passenger travelled much further than previously thought.
Note: the radius of infection is basically how far droplets containing virus will spread in the air before falling to the ground.
Virus survival on surfaces
Another thing that worried me is the information about how long the virus survives on surfaces such as metal, cloth, paper etc. It can survive – on surfaces – at 37C for days. That’s roughly 10C more than previously thought. That means this virus is hardier than we imagined. It also means that every infected person has the potential to infect people he or she is never in physical contact with.
Think about all the shopping trolley handles we touch, how many counters in shops, how many door knobs, tables, chairs… The list is endless, which means we have to be super vigilant, not just to protect ourselves, but to protect those we love. Do NOT soldier on, you could kill someone.
And finally, a word about government intervention. The countries that have been proactive about stopping the spread of Covid-19 are doing better than those which have not. We need to learn what works and do it in our own countries.
One thing which has worked particularly well in South Korea is ‘drive through testing’. You stay safe inside your car – your own little bubble of protection – and drive away without having to come in physical contact with others who may or may not be infected.
When I saw news footage of people waiting in long queues [here] to be tested, my first thought was, “well, if they didn’t have it before, they may well have it now”. Gatherings of people who may already be infected is such a bad idea…
Daniel Andrews [Premier of my state of Victoria] has declared that his government is going to take more stringent measures against the spread of Covid-19. I’m glad, but I still think that allowing Moomba and the Grand Prix to go ahead in Melbourne was a bad idea.
I understand that we do not yet have the level of community spread that triggers more ‘stringent’ measures, but we also don’t have the community awareness required to take this threat seriously. Traditional, normal public gatherings like these simply reinforce the idea that we’re ‘safe’.
We’re not safe, and we have to get used to that idea. We have to get used to taking precautions such as wearing masks and gloves, washing our hands religiously, staying away from crowds and air conditioned centres. We have to start doing these things now so that when things do get worse, they’ll get worse at a slower rate.
I cannot stress enough how important it is to slow the spread of this virus.
The following is a screenshot of a thread I read on Twitter last night. It’s from Northern Italy and describes a health care system teetering on the brink of collapse. Yet Northern Italy has a world class health system.
We have world class hospitals in Australia too, but people with the pneumonia stage of the infection need ventilators. These machines are capable of breathing for the patient until they are capable of breathing on their own again. But if everyone gets sick at once, how many are going to miss out on ventilators because there aren’t enough to go around? How many will die?
Deaths by age
Going back to the Dr John video, the stats showing the break down of deaths by age show that small children appear to be remarkably resilient:
From the age of 10 onwards, however, young people do die from Covid-19 as well. 0.2% of deaths amongst young people may not sound like much, but they are still people, real people.
Do you really want your ‘she’ll be right’ attitude to result in the death of your brother, sister, best friend, lover, wife, husband?
Or what about your parents? Aunts? Uncles? Grandparents?
We have to slow the spread of this virus, and we have to start now.
It’s officially 43 C in Melbourne, and my air conditioner died yesterday, yet the inside of the house is a relatively comfortable 26 C :
My office is a fair bit warmer because it’s a small room, and the desktop computer puts out quite a lot of heat [AMD processor], but it’s still bearable.
Magic? No, fire resistant shutters.
I wrote about my fire resistant shutters back in this post. They’ve never been tested in a bushfire situation, but by god they keep ordinary heat out!
The following pics were all taken from inside the house to show the shutters at work:
Almost every door, verandah and window in my house has been fitted with these fire resistant shutters. They weren’t cheap, but every winter since then, they’ve kept the warmth in, saving me money in heating costs. And in summer they keep the heat out, with or without the air conditioner. 🙂
Much as I love my shutters, however, I have to say that on their own they would not have been enough. Part of the reason they work as well as they do is that I insisted on having an insulating foam applied behind the door and window frames. The foam fills up all the gaps in construction conveniently hidden by the frames. A small thing, perhaps, but the foam has stopped those elusive draughts from leaching the heat from the house.
Apart from the shutters and the foam, two more things helped keep us from melting today. The first was the weather overnight. The temperature dropped to 14 C which allowed the cross ventilation in the house to cool everything down before the heat climbed again. If it had been hot overnight, we would have been in trouble.
The second thing is that orange towel shown in the last picture. And no, it’s not my washing. :p
That humble towel is wet, and it’s hanging in front of an oscillating fan. As the water in the towel evaporates, it cools the air. The fan then circulates that cooler air around the small family room and into the kitchen.
My jerry-rigged evaporative cooling is probably good enough for some light cooking but…bugger it, we’re having take away! Ahem. I deserve it.
If you’re an Aussie, I hope you stayed cool and safe today. If you’re from the northern climes, I hope you stayed warm and toasty.
As a gamer and denizen of Melbourne [Australia], how could I resist this New Atlas article about an AR game set in the city I love?
‘The game is the first in the True Crime Mysteries series by indie studio 10Tickles, helmed by husband-and-wife team Andy Yong and Emma Ramsay. The couple are both fascinated by true crime, history and the city of Melbourne itself, and so set out to build an augmented reality experience that tapped into all three.’

No, the title of this post is not a trick question. I saw this amazing tree while out driving, and I’d love to know what it is. Here are the pics I took:
Up and up and up….
The colour and shape of the leaves made me think it might be like the magnolia grandiflora we used to have in Dad’s old garden. It was small to medium tree-sized, but I don’t remember it having berries. I also can’t remember ever seeing one so very, very, very big! And those roots! Hard to believe it’s growing near the corner of a busy intersection in one of the more inner suburbs of Melbourne.
If you know what this tree is, please let me know in comments.
Although Professor Jay Sanjayan wasn’t giving away any technical secrets about his new process, the prospect of new materials to use in the printing process is very exciting. Nevertheless, it’s his comments about disruption to the construction industry that really got me thinking. 3D printing in construction makes it possible to automate construction.
But then what happens to the brickies and steel workers and carpenters whose jobs will become redundant?
I’m excited by the possibilities brought about by 3D printing, but also a little apprehensive. I firmly believe that some form of Universal Basic Income [UBI] will become necessary, possibly even in my lifetime. Sobering thought.
