Your fixed calorie budget stops weight loss through exercise
23 July 2024
This news, via Kurzgesagt, may not be what some people want to hear. Exercising is useful, necessary in fact, but not so much when it comes to trying to lose weight it seems.
Active people who work out regularly do burn more than inactive people. But only very little, often as low as 100 calories, the equivalent of a single apple. For some strange reason, the amount of calories you burn is pretty much unrelated to your lifestyle. Per kilo of body weight, your body has a fixed calorie budget it wants to burn per day.

COVID-19: third most lethal cause of death in Australia
10 July 2024
From The Daily Aus. Aside from being linked to a slight decrease in life expectancy, COVID-19 was the third highest cause of death in Australia in 2022, claiming almost ten-thousand lives:
COVID-19 was the third leading cause of death in Australia in 2022, according to AIHW. It was the first time in more than 50 years that an infectious disease has appeared in the top five causes of death.
COVID deaths were four times higher in 2022, compared to 2021. As a comparison, three-hundred-and-eight “influenza-associated” deaths were reported between 1 January and 9 October 2022.
Heart disease and dementia, respectively, were the top two causes of death in 2022. COVID may not dominate the conversation, as it did two or three years ago, but that has not diminished its severity in the least.

The health benefits of giving up drinking coffee
21 May 2024
As with many things we consume, the science on coffee can be conflicted. One decade caffeine consumption is a no-no, the next it seems coffee is quite beneficial. Regular readers will know I’m a coffee drinker, but in — what I consider to be — moderation: two (large serve) cups per day.
But some people struggle with coffee addiction. And the same people say their general health, and mental well-being, much improved when they stopped drinking coffee all together. Jesse Downes, based on Queensland’s Sunshine Coast, says he used to drink seven cups of coffee a day, before giving up completely about three months ago:
Three months into his coffee-free life, Mr Downes is noticing some changes. “The anxiety levels generally seem to be more managed, or reduced, if you like, and I would have to say there’s a sustained energy level,” he said.
Good for him. Just because many people enjoy something, doesn’t mean everyone will. I guess we all have our no-no vices. Mine would be alcohol and soft drink, both of which I only partake of a couple of times a year.

Everything good and bad, but mostly very bad, about smoking
10 May 2024
A Screen cap of Kurzgesagt’s Smoking is Awesome YouTube video.
This month Kurzgesagt takes on smoking. If you’re a non-smoker, this may help you understand why people like to have a puff:
Smoking helps you focus at work and is an excuse to take regular breaks, which is good for you mentally. It’s a tool against boredom, it suppresses your appetite, it makes bad moments feel less bad and good moments better. It’s social, fun together and a good way to make friends as smokers always group up. Your lips are one of the most sensitive parts of your body and putting something between them is deeply satisfying.
But smoking is a double-edged sword; the longer you partake, the greater your risk of suffering from heart disease, cancers, and all sorts of other maladies.
This should be a classroom educational resource.

Better building design will make air conditioning more environmentally friendly
5 September 2023
Ways are being sought to reduce the harmful environmental impact of air conditioning (AC) systems, which remain essential for health and well-being, starting with how buildings are designed and constructed in the first place:
“We need to design our buildings in a way that consumes less energy. We need to insulate them better. We need to ventilate them better,” explained Ankit Kalanki, a manager at Third Derivative, a climate tech accelerator co-founded by the sustainability research organization RMI. “These strategies are very important. We can reduce the air conditioning demand in the first place, but we cannot eliminate that.”

Pulling Weeds, Folding Laundry, a book by Leslie K. Lau
22 August 2023
Sydney based Australian writer and artist Leslie K. Lau recently self-published a book, Pulling Weeds, Folding Laundry. These are tasks many people probably don’t care to think much about, let alone carry out, but Lau saw them in a new light — as moments between moments — while undergoing treatment for cancer:
Ultimately, it is a story of how a cancer diagnosis revealed the reality of life, how volatility and uncertainty was in fact the norm and not the exception.
It is the retelling of a journey of finding peace, contentment, and joy in the moments between moments.
It is a tale of navigating hard times, perceived or otherwise, and coming out the other end.
What a wonderful way to say slow down and appreciate those seemingly insignificant moments in life, since they are still very much a part of it.

The variola virus AKA smallpox, more enlightened darkness from Kurzgesagt
9 August 2023
What’s with the doom and gloom emanating from Kurzgesagt recently? In the last few months their videos have covered a range of grim topics including biological weapons of mass destruction, the difficulty in beating cancer, black holes that destroy galaxies, and tales of woe about marauding extra-terrestrials who have Earth in their sights.
Anyone hoping for a reprieve this month will be disappointed though: their latest video explains exactly how nasty the variola virus, better known as smallpox, was, and the suffering and death it unleashed. While smallpox has officially been eradicated, the story of the virus is a potent reminder of how deadly some diseases can be. Let’s be thankful a vaccine was developed.

Kurzgesagt: the next pandemic could be made at home, scary hey?
4 July 2023
Advances in biotechnology are being made in leaps and bounds. On one hand what is being learnt is making the world safer, but on the other, there is a downside. While cures for deadly diseases are being developed, even nastier pathogens are being created at the same time. Or could be, as Kurzgesagt explains:
We are adding knowledge at unprecedented rates, while things get ever faster and cheaper to do. This speed means we can expect even more wonderful things for humanity. Lifesaving treatments, miracle crops and solutions to problems we can’t even imagine right now. But unfortunately progress cuts both ways. What can be used for good, can also be used for bad, by accident or on purpose. For all the good biotech will do for us, in the near future it also could easily kill many millions of people, in the worst case hundreds of millions. Worse than any nuclear bomb.

Why is cancer so hard to beat? Kurzgesagt tells us why
21 June 2023
Kurzgesagt take on the difficult questions, and come back with easy to follow, and entertaining, answers. Some forms of cancer have proved seemingly impossible to treat, but the German animation studio feels confident that will change in the not too distant future. Let’s hope so.
An undead city under siege, soldiers and police ruthlessly shooting down waves of zombies that flood from infected streets, trying to escape and infect more cities. This is what happens when your body fights cancer, more exciting than any movie. How does this battle for survival unfold?

Personal responsibility the only foil to Covid and long Covid
14 November 2022
Medical professionals are calling for more work from home mandates to combat the present surge in Covid infections in Australia. But the strain a new load of cases would impose on the health system is only one of their concerns. There is also the worry of an increase in instances of long Covid, something that becomes more likely, the more often someone is infected by Covid, says Dr Michael Bonning, NSW president of the Australian Medical Association.
“The risk of long COVID for everyone is really there and the more often you get infected, the higher your chances,” Bonning said. “[It doesn’t matter if] you’ve had it once and it was fairly mild.”
But Australian governments are reluctant to re-impose Covid mandates, saying Australians must take “personal responsibility” and “learn to live with Covid”. While this is true, I’m not sure Covid, as opposed to possibly the flu or common cold, is something we can really afford to live with, particularly if it leads to long Covid.
Long Covid, which can last for two months, some times longer, sees sufferers experience symptoms including extreme fatigue, cough, breathlessness, joint or muscle pain, chest pain, memory and concentration problems, and reduced appetite and weight loss, among other things. That’s not something to look forward to.
But then again, neither are lockdowns, or other restrictions. While they saw short term success, infection rates generally saw a decline, Covid returned once restrictions were removed. Covid has us in a bind. To live as normally as possible, free of Covid and long Covid, and restrictions, personal responsibility is one of the few options we have. But for “personal responsibility” to be effective, everyone has to do the right thing.
At its most basic, this means mask wearing where crowds are present, keeping up to date with Covid vaccinations, and isolating if infected. Covid is a slippery beast, and has had us marching to its beat for three years. The only real hope is an effective treatment is forthcoming, that will eventually eliminate the disease all together.
