The grim Danish philosophy that actually makes people happy
Denmark's 10 Jante Laws are grim, and yet they bring so much happiness.

The United States of America was ranked the 19th happiest country in the world in 2016 in the World Happiness Report. A part of America's unhappiness can be linked to the social structure of the country.
Being American means culturally striving to be the best and going to great pains to differentiate yourself as unique. It is not enough to be on the basketball team in high school, instead you have to be the MVP. It is not enough to get straight As, but you should also take all of the AP and IB classes, and have as many extra-curricular activities as possible at the same time. It's not enough to work at a large business, you also strive for that cozy CEO position and start that ladder-climb early.

What does that have to do with happiness? Take a look at Denmark, repeatedly voted as the world's happiest country (although it has just been knocked back to second place in the 2017 World Happiness Report). Denmark's social structure is very different to that of the US. Danes tend to believe in something called Jante Law, which has 10 rules all around the idea of accepting the average. Quartz reports that Jante Law is everywhere in Denmark, even if no one is discussing or admitting it. In online comic Scandinavia and the World, the character of Denmark has been consistent in its exemplification of Jante even though it's never named as such.
Jante persists in the culture in every way and, according to Ourhouseinaarhus, even affects the school system. There is no competitive school system, no advanced programs for gifted learners. The schools must all be equal, and the students must help each other rather than vie for 'the best.' There are no rewards program, no trophies for the students who graded better. As the blogger commented, the Danish children learn early on about Jante.
The laws themselves are simple. They all encourage the idea that you are average, and that's just fine.
1. You're not to think you are anything special.
2. You're not to think you are as good as we are.
3. You're not to think you are smarter than we are.
4. You're not to convince yourself that you are better than we are.
5. You're not to think you know more than we do.
6. You're not to think you are more important than we are.
7. You're not to think you are good at anything.
8. You're not to laugh at us.
9. You're not to think anyone cares about you.
10. You're not to think you can teach us anything.
The laws, when written out, are meant to look horrifying and quite intimidating. They come from a book written by Aksel Sandemose, and he was trying to satirize what it was like in Scandinavian small towns in his novel A Fugitive Crosses His Tracks (En Flyktning Krysser Sitt Spor). When Sandemose named that town Jante, he gave name to something that already existed in practice in Scandinavia.
While the idea of Jante Law is culturally relevant, according to Lindsay Dupuis, a therapist in Copenhagen, it's not discussed in everyday life as a conscious practice, rather it's lived out — talking about it seems redundant. Why discuss oxygen intake when you were born breathing it? It materializes like this: nobody brags when their child is named number one in their math class. They don't talk about who gave the best speech at their work function, or discuss who's been promoted most at work. This is not to say that the Danes are not ambitious, they're just as ambitious as everyone else. They just don't brag about it, or stress over doing more.
“By definition, most of us are average," remarks psychologist Madeline Levine in her Big Think discussion of the topic. By the very principle of the word average, most of society falls somewhere between worst and best, and struggling against that only leads to anxiety. It's by no means futile to try, but intentions matter — do you want to achieve something, or do you want to beat someone else at their achievement? As Alain de Botton writes in Status Anxiety: “Anxiety is the handmaiden of contemporary ambition."
Psychologist Barry Schwartz has commented on this very thing. He's stated in his book, The Paradox of Choice: Why More is Less, that it is necessary for a person's mental health to accept the average, the 'good enough.' This is necessary because it may be impossible to know if 'the best' is ever reached, and often, perfection is unattainable. It may be impossible to know if one had the best score, but it is easily understood if the score was good enough. It is impossible to quantify if one is the best musician, but good enough is well within reach. Schwartz has pressed that psychologically speaking, this continued push to rise above average has negative consequences on mental health.
… what happens is this imagined alternative induces you to regret the decision you made, and this regret subtracts from the satisfaction you get out of the decision you made, even if it was a good decision.
This means that Jante is, psychologically speaking, a far healthier way of thinking. To accept an average life means that one would get more satisfaction from it. To accept the 'good enough' means that one would have a far better experience with it. In addition, the Danish also have hygge which is, according to The New Yorker and Oxford Dictionary, the concept of being cozy and comfortable as a way of creating the sense of health and happiness. The Oxford Dictionary even reports that hygge is a defining quality of the Danes. That, plus the 10 rules of Jante Law, all add up to the low-stress environment that is Denmark. By slipping into something a little fleecier, and lowering your expectations you will occasionally find yourself pleasantly impressed when those expectations are outdone. All it takes is a sense of being good enough to be comfortable and cozy in life: Jante and hygge.

How tiny bioelectronic implants may someday replace pharmaceutical drugs
Scientists are using bioelectronic medicine to treat inflammatory diseases, an approach that capitalizes on the ancient "hardwiring" of the nervous system.
Left: The vagus nerve, the body's longest cranial nerve. Right: Vagus nerve stimulation implant by SetPoint Medical.
- Bioelectronic medicine is an emerging field that focuses on manipulating the nervous system to treat diseases.
- Clinical studies show that using electronic devices to stimulate the vagus nerve is effective at treating inflammatory diseases like rheumatoid arthritis.
- Although it's not yet approved by the US Food and Drug Administration, vagus nerve stimulation may also prove effective at treating other diseases like cancer, diabetes and depression.
The nervous system’s ancient reflexes
<p>You accidentally place your hand on a hot stove. Almost instantaneously, your hand withdraws.</p><p>What triggered your hand to move? The answer is <em>not</em> that you consciously decided the stove was hot and you should move your hand. Rather, it was a reflex: Skin receptors on your hand sent nerve impulses to the spinal cord, which ultimately sent back motor neurons that caused your hand to move away. This all occurred before your "conscious brain" realized what happened.</p><p>Similarly, the nervous system has reflexes that protect individual cells in the body.</p><p>"The nervous system evolved because we need to respond to stimuli in the environment," said Dr. Tracey. "Neural signals don't come from the brain down first. Instead, when something happens in the environment, our peripheral nervous system senses it and sends a signal to the central nervous system, which comprises the brain and spinal cord. And then the nervous system responds to correct the problem."</p><p>So, what if scientists could "hack" into the nervous system, manipulating the electrical activity in the nervous system to control molecular processes and produce desirable outcomes? That's the chief goal of bioelectronic medicine.</p><p>"There are billions of neurons in the body that interact with almost every cell in the body, and at each of those nerve endings, molecular signals control molecular mechanisms that can be defined and mapped, and potentially put under control," Dr. Tracey said in a <a href="https://www.youtube.com/watch?v=AJH9KsMKi5M" target="_blank">TED Talk</a>.</p><p>"Many of these mechanisms are also involved in important diseases, like cancer, Alzheimer's, diabetes, hypertension and shock. It's very plausible that finding neural signals to control those mechanisms will hold promises for devices replacing some of today's medication for those diseases."</p><p>How can scientists hack the nervous system? For years, researchers in the field of bioelectronic medicine have zeroed in on the longest cranial nerve in the body: the vagus nerve.</p>The vagus nerve

<p>The vagus nerve ("vagus" meaning "wandering" in Latin) comprises two nerve branches that stretch from the brainstem down to the chest and abdomen, where nerve fibers connect to organs. Electrical signals constantly travel up and down the vagus nerve, facilitating communication between the brain and other parts of the body.</p><p>One aspect of this back-and-forth communication is inflammation. When the immune system detects injury or attack, it automatically triggers an inflammatory response, which helps heal injuries and fend off invaders. But when not deployed properly, inflammation can become excessive, exacerbating the original problem and potentially contributing to diseases.</p><p>In 2002, Dr. Tracey and his colleagues discovered that the nervous system plays a key role in monitoring and modifying inflammation. This occurs through a process called the <a href="https://www.nature.com/articles/nature01321" target="_blank" rel="noopener noreferrer">inflammatory reflex</a>. In simple terms, it works like this: When the nervous system detects inflammatory stimuli, it reflexively (and subconsciously) deploys electrical signals through the vagus nerve that trigger anti-inflammatory molecular processes.</p><p>In rodent experiments, Dr. Tracey and his colleagues observed that electrical signals traveling through the vagus nerve control TNF, a protein that, in excess, causes inflammation. These electrical signals travel through the vagus nerve to the spleen. There, electrical signals are converted to chemical signals, triggering a molecular process that ultimately makes TNF, which exacerbates conditions like rheumatoid arthritis.</p><p>The incredible chain reaction of the inflammatory reflex was observed by Dr. Tracey and his colleagues in greater detail through rodent experiments. When inflammatory stimuli are detected, the nervous system sends electrical signals that travel through the vagus nerve to the spleen. There, the electrical signals are converted to chemical signals, which trigger the spleen to create a white blood cell called a T cell, which then creates a neurotransmitter called acetylcholine. The acetylcholine interacts with macrophages, which are a specific type of white blood cell that creates TNF, a protein that, in excess, causes inflammation. At that point, the acetylcholine triggers the macrophages to stop overproducing TNF – or inflammation.</p><p>Experiments showed that when a specific part of the body is inflamed, specific fibers within the vagus nerve start firing. Dr. Tracey and his colleagues were able to map these relationships. More importantly, they were able to stimulate specific parts of the vagus nerve to "shut off" inflammation.</p><p>What's more, clinical trials show that vagus nerve stimulation not only "shuts off" inflammation, but also triggers the production of cells that promote healing.</p><p>"In animal experiments, we understand how this works," Dr. Tracey said. "And now we have clinical trials showing that the human response is what's predicted by the lab experiments. Many scientific thresholds have been crossed in the clinic and the lab. We're literally at the point of regulatory steps and stages, and then marketing and distribution before this idea takes off."<br></p>The future of bioelectronic medicine

In the future, it may also be used to treat cancer, diabetes, and depression.

<p>Vagus nerve stimulation is currently awaiting approval by the US Food and Drug Administration, but so far, it's proven safe and effective in clinical trials on humans. Dr. Tracey said vagus nerve stimulation could become a common treatment for a wide range of diseases, including cancer, Alzheimer's, diabetes, hypertension, shock, depression and diabetes.</p><p>"To the extent that inflammation is the problem in the disease, then stopping inflammation or suppressing the inflammation with vagus nerve stimulation or bioelectronic approaches will be beneficial and therapeutic," he said.</p><p>Receiving vagus nerve stimulation would require having an electronic device, about the size of lima bean, surgically implanted in your neck during a 30-minute procedure. A couple of weeks later, you'd visit, say, your rheumatologist, who would activate the device and determine the right dosage. The stimulation would take a few minutes each day, and it'd likely be unnoticeable.</p><p>But the most revolutionary aspect of bioelectronic medicine, according to Dr. Tracey, is that approaches like vagus nerve stimulation wouldn't come with harmful and potentially deadly side effects, as many pharmaceutical drugs currently do.</p><p>"A device on a nerve is not going to have systemic side effects on the body like taking a steroid does," Dr. Tracey said. "It's a powerful concept that, frankly, scientists are quite accepting of—it's actually quite amazing. But the idea of adopting this into practice is going to take another 10 or 20 years, because it's hard for physicians, who've spent their lives writing prescriptions for pills or injections, that a computer chip can replace the drug."</p><p>But patients could also play a role in advancing bioelectronic medicine.</p><p>"There's a huge demand in this patient cohort for something better than they're taking now," Dr. Tracey said. "Patients don't want to take a drug with a black-box warning, costs $100,000 a year and works half the time."</p><p>Michael Dowling, president and CEO of Northwell Health, elaborated:</p><p>"Why would patients pursue a drug regimen when they could opt for a few electronic pulses? Is it possible that treatments like this, pulses through electronic devices, could replace some drugs in the coming years as preferred treatments? Tracey believes it is, and that is perhaps why the pharmaceutical industry closely follows his work."</p><p>Over the long term, bioelectronic approaches are unlikely to completely replace pharmaceutical drugs, but they could replace many, or at least be used as supplemental treatments.</p><p>Dr. Tracey is optimistic about the future of the field.</p><p>"It's going to spawn a huge new industry that will rival the pharmaceutical industry in the next 50 years," he said. "This is no longer just a startup industry. [...] It's going to be very interesting to see the explosive growth that's going to occur."</p>Just how cold was the Ice Age? New study finds the temperature
Researchers figure out the average temperatures of the last ice age on Earth.

Best. Science. Fiction. Show. Ever.
"The Expanse" is the best vision I've ever seen of a space-faring future that may be just a few generations away.
- Want three reasons why that headline is justified? Characters and acting, universe building, and science.
- For those who don't know, "The Expanse" is a series that's run on SyFy and Amazon Prime set about 200 years in the future in a mostly settled solar system with three waring factions: Earth, Mars, and Belters.
- No other show I know of manages to use real science so adeptly in the service of its story and its grand universe building.

<p>Now, I get it if you don't agree with me. I love "Star Trek" and I thought "Battlestar Galactica" (the new one) was amazing and I do adore "The Mandalorian". They are all fun and important and worth watching and thinking about. And maybe you love them more than anything else. But when you sum up the acting, the universe building, and the use of real science where it matters, I think nothing can beat "The Expanse". And with a <a href="https://www.rottentomatoes.com/tv/the_expanse" target="_blank">Rotten Tomato</a> average rating of 93%, I'm clearly not the only one who feels this way.</p><p>Best.</p><p>Show.</p><p>Ever. </p>How exercise changes your brain biology and protects your mental health
Contrary to what some might think, the brain is a very plastic organ.
As with many other physicians, recommending physical activity to patients was just a doctor chore for me – until a few years ago. That was because I myself was not very active.
Here's a 10-step plan to save our oceans
By 2050, there may be more plastic than fish in the sea.
