All of this creates a vicious cycle, forcing a continued reliance on the corporations that helped create the situation in the first place. More than half of Mali’s citizens live below the international poverty line, while their nation’s wealth lines the pockets of foreign corporations and corrupt officials.

🟢The original ring of power
A ring with supernatural abilities tempts its beholder with power. But there are no hobbits, dwarves, or Valkyries in this tale. In fact, the legend of the Ring of Gyges appeared long before those characters were ever committed to paper: more than 2,000 years ago, in the Greek philosopher Plato’s “Republic.” The story surfaces as the philosopher, Socrates, and his student, Glaucon, discuss why people act justly. Is it because it’s what’s right? Or because it’s a convention that’s enforced through punishment and reward? Playing devil’s advocate, Glaucon argues against Socrates and recounts the following story...
Long ago, a shepherd named Gyges was tending his flock when an earthquake struck, ripping an opening to the ground. The chasm drew Gyges in. There, his eyes alighted upon a bronze horse, the doors to its central chamber ajar. Peering inside, Gyges discovered the corpse of a giant. On its finger, a golden ring, which Gyges pocketed before retracing his steps. Later, he sat among the other shepherds, fiddling with the mysterious ring when, suddenly, after absentmindedly twirling its stone, he became invisible. When he turned the stone back in the opposite direction, he reappeared. Emboldened by the ring’s powers, new possibilities bloomed before him, and a sordid plan hatched in his mind. Gyges became a messenger to the king of Lydia, and, inside the palace, used the ring to prowl undetected. He seduced the queen and convinced her to betray her husband. And soon Gyges, once a humble shepherd, had murdered the monarch and claimed the kingdom.
Glaucon tells this story to illustrate how people can apparently benefit by acting unjustly. After all, wouldn’t any rational person act like Gyges if presented the opportunity to get what they desired without consequence?
Exploring this argument, Glaucon breaks all good things into three classes. The first kinds, we desire for their own sake, like the experience of harmless pleasure. The second, we want only for the value they bring, though they may be onerous, like exercise or medicine. The third class comprises things we desire for their own sake and the value they offer, like knowledge and health. Glaucon argues that justice belongs to the second class of good: it’s a burden that nevertheless brings rewards. The only reason anyone conducts themselves virtuously, he reasons, is due to external influences. So it’s appearing— not actually being— virtuous that matters.
Socrates, as written by Plato, disagrees, countering that justice belongs to the third class of good, offering both extrinsic and intrinsic benefits. Socrates argues that the human soul has three parts: reason, spirit, and appetite. Reason guides an individual to truth and knowledge, and is influenced by either spirit or appetite. Spirit is righteous, ambitious, and the source of bold action, while appetite consists of baser, bodily desires.
To Socrates, the philosopher is led by reason, and their spirit keeps their appetite in check, making them the most just and the happiest. Even without consequences for self-serving wrongdoings, they wouldn't commit them. Meanwhile, the tyrant succumbs to appetite and acts unjustly. So, while Gyges may have attained power and wealth, Socrates implies that his soul would be in disharmony. He’d be enslaved to his own base desires rather than guided by reason and wouldn't be truly happy.
Before Plato penned this discussion, Chinese philosopher Confucius similarly reasoned that by simply acting justly, one also benefits oneself. After, modern Western philosophers voiced varying beliefs. Thomas Hobbes, for instance, argued that the state of nature is violent and selfish. Justice, therefore, is imposed by authority. John Locke, in contrast, asserted that people are naturally obligated to act justly and they agree to participate in civil society to secure their natural rights.

The allegory of the ill-gotten magical ring that lures its wearer towards their darkest desires continues to inspire. So if the ring of Gyges fell into your hands, what would you do?

🟢Why do we feel nostalgia?
In the late 17th century, a medical student named Johannes Hofer noticed a strange illness affecting Swiss mercenaries serving abroad. Its symptoms, including fatigue, insomnia, irregular heartbeat, indigestion, and fever were so strong, the soldiers often had to be discharged. As Hofer discovered, the cause was not some physical disturbance, but an intense yearning for their mountain homeland. He dubbed the condition nostalgia, from the Greek "nostos" for homecoming and "algos" for pain or longing. At first, nostalgia was considered a particularly Swiss affliction. Some doctors proposed that the constant sound of cowbells in the Alps caused trauma to the ear drums and brain. Commanders even forbade their soldiers from singing traditional Swiss songs for fear that they'd lead to desertion or suicide. But as migration increased worldwide, nostalgia was observed in various groups. It turned out that anyone separated from their native place for a long time was vulnerable to nostalgia. And by the early 20th century, professionals no longer viewed it as a neurological disease, but as a mental condition similar to depression. Psychologists of the time speculated that it represented difficulties letting go of childhood, or even a longing to return to one's fetal state. But over the next few decades, the understanding of nostalgia changed in two important ways. Its meaning expanded from indicating homesickness to a general longing for the past. And rather than an awful disease, it began to be seen as a poignant and pleasant experience. Perhaps the most famous example of this was captured by French author Marcel Proust. He described how tasting a madeleine cake he had not eaten since childhood triggered a cascade of warm and powerful sensory associations. So what caused such a major reversal in our view of nostalgia? Part of it has to do with science. Psychology shifted away from pure theory and towards more careful and systematic empirical observation. So professionals realized that many of the negative symptoms may have been simply correlated with nostalgia rather than caused by it. And, in fact, despite being a complex emotional state that can include feelings of loss and sadness, nostalgia doesn't generally put people in a negative mood. Instead, by allowing individuals to remember personally meaningful and rewarding experiences they shared with others, nostalgia can boost psychological well-being. Studies have shown that inducing nostalgia in people can help increase their feelings of self-esteem and social belonging, encourage psychological growth, and even make them act more charitably. So rather than being a cause of mental distress, nostalgia can be a restorative way of coping with it. For instance, when people experience negative emotional states, they tend to naturally use nostalgia to reduce distress and restore well-being. Today, it seems that nostalgia is everywhere, partially because advertisers have discovered how powerful it is as a marketing technique. It's tempting to think of this as a sign of us being stuck in the past, but that's not really how nostalgia works. Instead, nostalgia helps us remember that our lives can have meaning and value, helping us find the confidence and motivation to face the challenges of the future.

🟢Can the economy grow forever?
Let’s say you discover a magical gold coin that doubles every 25 years. 75 years later, you’d only have eight coins. But 1,000 years later, you’d have over a trillion. And in just 4,600 years, your gold coins would outweigh the observable universe.
This periodic doubling is an example of exponential growth, and while we’re not in any danger of discovering a real-life golden goose-coin, something almost as consequential has been growing like this for the past 200 or so years: the global economy.
Many economists think that an eternally growing economy is necessary to keep improving people’s lives, and that if the global economy stops growing, people would fight more over the fixed amount of value that exists, rather than working to generate new value.
That raises the question: is infinite growth possible on a finite planet?
We measure economic growth by tracking the total financial value of everything a country (or the world) produces and sells on the market. These products can help us meet basic needs or improve our individual and collective quality of life. But they also, crucially, take resources to invent, build, or maintain.
For example, this smartphone. It’s valuable in part because it contains aluminum, gallium, and silicon, all of which took energy and resources to mine, purify, and turn into a phone. It’s also valuable because of all the effort that went into designing the hardware and writing the software. And it’s also valuable because a guy in a black turtleneck got up on stage and told you it was.
So how do we grow the total financial value of all things? One way is to make more things. Another way is to invent new things. However you do it, growing the economy requires resources and energy. And eventually, won’t we just run out?
To answer this question, let's consider what goes into the economy and what comes out of it: its inputs are labor, capital— which you can think of as money— and natural resources, like water or energy. Its output is value. Over the past 200 years, economies have gotten exponentially more efficient at producing value.
If we, as a species, are able to keep upgrading our economies so that they get ever-more efficient, we could theoretically pump out more and more value using the same— or, let’s be really ambitious here— fewer resources.
So, how do we do that? How do we increase efficiency? With new technologies.
This is where we hit a snag.
New tech, in addition to making things more efficient, can also generate new demand, which ends up using more resources.
We’re actually not in imminent danger of running out of most resources. But we have a much bigger and more immediate problem: the global economy, and in particular those of rich countries, is driving climate change and destroying valuable natural environments on which all of us depend— soil, forests, fisheries, and countless other resources that help keep our civilization running.
So, what should we do?
This is where economists disagree.
Most economists think that new ideas will be able to fix most of these problems. They argue that, in the same way that exponentially increasing resource and energy use have fueled exponential economic growth, human ingenuity has also increased exponentially, and will rise to meet these challenges in ways that we simply can't predict. For example, between 2000 and 2014, Germany grew their GDP by 16%, while cutting CO2 emissions by 12%.
That’s impressive, but it’s not cutting emissions fast enough to limit warming to 1.5 degrees Celsius. For this reason and others, some economists think the solution is to reengineer our economies completely. They make the case that what we should really be doing is weaning ourselves from the addiction to growth and shifting to a post-growth economy.

What would that look like? A post-growth economy wouldn’t assume that the economy should grow; instead, it would require us to focus on improving what we really need— things like renewable energy, healthcare, and public transportation. To do that, post-growth economists suggest that rich countries should do things like guarantee living wages, reduce wealth and income inequality, and ensure universal access to public services, like healthcare. In such an economy, people would be theoretically less dependent on their jobs to earn their living or get healthcare, so it might be more feasible to scale down production of things deemed less necessary.
But this raises other questions: who gets to define what’s necessary? How would we resolve the inevitable disagreements? Could we really do away with entire industries?
The “we’ll come up with new ideas to solve these problems” approach can seem as realistic as, well, a magical gold coin. And the “we have to fundamentally change our economies” approach can seem politically daunting, particularly in rich countries. One way or another, we have to find a way to benefit everyone while also taking care of our planet.

🟢Am I dying? The honest answer
I've been a critical care EMT for the past seven years in Suffolk County, New York. I've been a first responder in a number of incidents ranging from car accidents to Hurricane Sandy.
If you are like most people, death might be one of your greatest fears. Some of us will see it coming. Some of us won't. There is a little-known documented medical term called impending doom. It's almost a symptom. As a medical provider, I'm trained to respond to this symptom like any other, so when a patient having a heart attack looks at me and says, "I'm going to die today," we are trained to reevaluate the patient's condition.
Throughout my career, I have responded to a number of incidents where the patient had minutes left to live and there was nothing I could do for them. With this, I was faced with a dilemma: Do I tell the dying that they are about to face death, or do I lie to them to comfort them? Early in my career, I faced this dilemma by simply lying. I was afraid. I was afraid if I told them the truth, that they would die in terror, in fear, just grasping for those last moments of life.
That all changed with one incident. Five years ago, I responded to a motorcycle accident. The rider had suffered critical, critical injuries. As I assessed him, I realized that there was nothing that could be done for him, and like so many other cases, he looked me in the eye and asked that question: "Am I going to die?" In that moment, I decided to do something different. I decided to tell him the truth. I decided to tell him that he was going to die and that there was nothing I could do for him. His reaction shocked me to this day. He simply laid back and had a look of acceptance on his face. He was not met with that terror or fear that I thought he would be. He simply laid there, and as I looked into his eyes, I saw inner peace and acceptance. From that moment forward, I decided it was not my place to comfort the dying with my lies. Having responded to many cases since then where patients were in their last moments and there was nothing I could do for them, in almost every case, they have all had the same reaction to the truth, of inner peace and acceptance. In fact, there are three patterns I have observed in all these cases.
The first pattern always kind of shocked me. Regardless of religious belief or cultural background, there's a need for forgiveness. Whether they call it sin or they simply say they have a regret, their guilt is universal. I had once cared for an elderly gentleman who was having a massive heart attack. As I prepared myself and my equipment for his imminent cardiac arrest, I began to tell the patient of his imminent demise. He already knew by my tone of voice and body language. As I placed the defibrillator pads on his chest, prepping for what was going to happen, he looked me in the eye and said, "I wish I had spent more time with my children and grandchildren instead of being selfish with my time." Faced with imminent death, all he wanted was forgiveness.
The second pattern I observe is the need for remembrance. Whether it was to be remembered in my thoughts or their loved ones', they needed to feel that they would be living on. There's a need for immortality within the hearts and thoughts of their loved ones, myself, my crew, or anyone around. Countless times, I have had a patient look me in the eyes and say, "Will you remember me?"
The final pattern I observe always touched me the deepest, to the soul. The dying need to know that their life had meaning. They need to know that they did not waste their life on meaningless tasks.

This came to me very, very early in my career. I had responded to a call. There was a female in her late 50s severely pinned within a vehicle. She had been t-boned at a high rate of speed, critical, critical condition. As the fire department worked to remove her from the car, I climbed in to begin to render care. As we talked, she had said to me, "There was so much more I wanted to do with my life." She had felt she had not left her mark on this Earth. As we talked further, it would turn out that she was a mother of two adopted children who were both on their way to medical school. Because of her, two children had a chance they never would have had otherwise and would go on to save lives in the medical field as medical doctors. It would end up taking 45 minutes to free her from the vehicle. However, she perished prior to freeing her.
I believed what you saw in the movies: when you're in those last moments that it's strictly terror, fear. I have come to realize, regardless of the circumstance, it's generally met with peace and acceptance, that it's the littlest things, the littlest moments, the littlest things you brought into the world that give you peace in those final moments.
Thank you.

🟢What makes muscles grow?
Muscles. We have over 600 of them. They make up between 1/3 and 1/2 of our body weight, and along with connective tissue, they bind us together, hold us up, and help us move. And whether or not body building is your hobby, muscles need your constant attention because the way you treat them on a daily basis determines whether they will wither or grow. Say you're standing in front of a door, ready to pull it open. Your brain and muscles are perfectly poised to help you achieve this goal. First, your brain sends a signal to motor neurons inside your arm. When they receive this message, they fire, causing muscles to contract and relax, which pull on the bones in your arm and generate the needed movement. The bigger the challenge becomes, the bigger the brain's signal grows, and the more motor units it rallies to help you achieve your task. But what if the door is made of solid iron? At this point, your arm muscles alone won't be able to generate enough tension to pull it open, so your brain appeals to other muscles for help. You plant your feet, tighten your belly, and tense your back, generating enough force to yank it open. Your nervous system has just leveraged the resources you already have, other muscles, to meet the demand. While all this is happening, your muscle fibers undergo another kind of cellular change. As you expose them to stress, they experience microscopic damage, which, in this context, is a good thing. In response, the injured cells release inflammatory molecules called cytokines that activate the immune system to repair the injury. This is when the muscle-building magic happens. The greater the damage to the muscle tissue, the more your body will need to repair itself. The resulting cycle of damage and repair eventually makes muscles bigger and stronger as they adapt to progressively greater demands. Since our bodies have already adapted to most everyday activities, those generally don't produce enough stress to stimulate new muscle growth. So, to build new muscle, a process called hypertrophy, our cells need to be exposed to higher workloads than they are used to. In fact, if you don't continuously expose your muscles to some resistance, they will shrink, a process known as muscular atrophy. In contrast, exposing the muscle to a high-degree of tension, especially while the muscle is lengthening, also called an eccentric contraction, generates effective conditions for new growth. However, muscles rely on more than just activity to grow. Without proper nutrition, hormones, and rest, your body would never be able to repair damaged muscle fibers. Protein in our diet preserves muscle mass by providing the building blocks for new tissue in the form of amino acids. Adequate protein intake, along with naturally occurring hormones, like insulin-like growth factor and testosterone, help shift the body into a state where tissue is repaired and grown. This vital repair process mainly occurs when we're resting, especially at night while sleeping. Gender and age affect this repair mechanism, which is why young men with more testosterone have a leg up in the muscle building game. Genetic factors also play a role in one's ability to grow muscle. Some people have more robust immune reactions to muscle damage, and are better able to repair and replace damaged muscle fibers, increasing their muscle-building potential. The body responds to the demands you place on it. If you tear your muscles up, eat right, rest and repeat, you'll create the conditions to make your muscles as big and strong as possible. It is with muscles as it is with life: Meaningful growth requires challenge and stress.

🟢What would happen if you didn't drink water?
Water is virtually everywhere, from soil moisture and ice caps, to the cells inside our own bodies. Depending on factors like location, fat index, age, and sex, the average human is between 55-60% water. At birth, human babies are even wetter. Being 75% water, they are swimmingly similar to fish. But their water composition drops to 65% by their first birthday. So what role does water play in our bodies, and how much do we actually need to drink to stay healthy? The H20 in our bodies works to cushion and lubricate joints, regulate temperature, and to nourish the brain and spinal cord. Water isn't only in our blood. An adult's brain and heart are almost three quarters water. That's roughly equivalent to the amount of moisture in a banana. Lungs are more similar to an apple at 83%. And even seemingly dry human bones are 31% water. If we are essentially made of water, and surrounded by water, why do we still need to drink so much? Well, each day we lose two to three liters through our sweat, urine, and bowel movements, and even just from breathing. While these functions are essential to our survival, we need to compensate for the fluid loss. Maintaining a balanced water level is essential to avoid dehydration or over-hydration, both of which can have devastating effects on overall health. At first detection of low water levels, sensory receptors in the brain's hypothalamus signal the release of antidiuretic hormone. When it reached the kidneys, it creates aquaporins, special channels that enable blood to absorb and retain more water, leading to concentrated, dark urine. Increased dehydration can cause notable drops in energy, mood, skin moisture, and blood pressure, as well as signs of cognitive impairment. A dehydrated brain works harder to accomplish the same amount as a normal brain, and it even temporarily shrinks because of its lack of water. Over-hydration, or hyponatremia, is usually caused by overconsumption of water in a short amount of time. Athletes are often the victims of over-hydration because of complications in regulating water levels in extreme physical conditions. Whereas the dehydrated brain amps up the production of antidiuretic hormone, the over-hydrated brain slows, or even stops, releasing it into the blood. Sodium electrolytes in the body become diluted, causing cells to swell. In severe cases, the kidneys can't keep up with the resulting volumes of dilute urine. Water intoxication then occurs, possibly causing headache, vomiting, and, in rare instances, seizures or death. But that's a pretty extreme situation. On a normal, day-to-day basis, maintaining a well-hydrated system is easy to manage for those of us fortunate enough to have access to clean drinking water. For a long time, conventional wisdom said that we should drink eight glasses a day. That estimate has since been fine-tuned. Now, the consensus is that the amount of water we need to imbibe depends largely on our weight and environment. The recommended daily intake varies from between 2.5-3.7 liters of water for men, and about 2-2.7 liters for women, a range that is pushed up or down if we are healthy, active, old, or overheating. While water is the healthiest hydrator, other beverages, even those with caffeine like coffee or tea, replenish fluids as well. And water within food makes up about a fifth of our daily H20 intake. Fruits and vegetables like strawberries, cucumbers, and even broccoli are over 90% water, and can supplement liquid intake while providing valuable nutrients and fiber. Drinking well might also have various long-term benefits. Studies have shown that optimal hydration can lower the chance of stroke, help manage diabetes, and potentially reduce the risk of certain types of cancer. No matter what, getting the right amount of liquid makes a world of difference in how you'll feel, think, and function day to day.
