Patterns that didn’t change one generation to the next, Dr. Conway called still lifes — such as the four-celled block, the six-celled beehive or the eight-celled pond. Patterns that took a long time to stabilize, he called methuselahs.

The second thing Life shows us is something that Darwin hit upon when he was looking at Life, the organic version. Complexity arises from simplicity!

I first encountered Life at the Exploratorium in San Francisco in 1978. I was hooked immediately by the thing that has always hooked me — watching complexity arise out of simplicity.

Life shows you two things. The first is sensitivity to initial conditions. A tiny change in the rules can produce a huge difference in the output, ranging from complete destruction (no dots) through stasis (a frozen pattern) to patterns that keep changing as they unfold.

Life shows us complex virtual “organisms” arising out of the interaction of a few simple rules — so goodbye “Intelligent Design.”

I’ve wondered for decades what one could learn from all that Life hacking. I recently realized it’s a great place to try to develop “meta-engineering” — to see if there are general principles that govern the advance of engineering and help us predict the overall future trajectory of technology.

Given that Conway’s proof that the Game of Life can be made to simulate a Universal Computer — that is, it could be “programmed” to carry out any computation that a traditional computer can do — the extremely simple rules can give rise to the most complex and most unpredictable behavior possible. This means that there are certain properties of the Game of Life that can never be predicted, even in principle!

I use the Game of Life to make vivid for my students the ideas of determinism, higher-order patterns and information. One of its great features is that nothing is hidden; there are no black boxes in Life, so you know from the outset that anything that you can get to happen in the Life world is completely unmysterious and explicable in terms of a very large number of simple steps by small items.

In Thomas Pynchon’s novel “Gravity’s Rainbow,” a character says, “But you had taken on a greater and more harmful illusion. The illusion of control. That A could do B. But that was false. Completely. No one can do. Things only happen.”This is compelling but wrong, and Life is a great way of showing this.

In Life, we might say, things only happen at the pixel level; nothing controls anything, nothing does anything. But that doesn’t mean that there is no such thing as action, as control; it means that these are higher-level phenomena composed (entirely, with no magic) from things that only happen.

it did have a big impact on beginner programmers, like me in the 90s, giving them a sense of wonder and a kind of confidence that some easy-to-code math models can produce complex and beautiful results. It’s like a starter kit for future software engineers and hackers, together with Mandelbrot Set, Lorenz Attractor, et cetera.

if we think about our everyday life, about corporations and governments, the cultural and technical infrastructures humans built for thousands of years, they are not unlike the incredible machines that are engineered in Life.

In normal times, they are stable and we can keep building stuff one component upon another, but in harder times like this pandemic or a new Cold War, we need something that is more resilient and can prepare for the unpreparable. That would need changes in our “rules of life,” which we take for granted.

That’s what chaos is about. The Game of Life, or a kinky dynamical system like a pair of pendulums, or a candle flame, or an ocean wave, or the growth of a plant — they aren’t readily predictable. But they are not random. They do obey laws, and there are certain kinds of patterns — chaotic attractors — that they tend to produce. But again, unpredictable is not random. An important and subtle distinction which changed my whole view of the world.

William Poundstone— Author of “The Recursive Universe: Cosmic Complexity and the Limits of Scientific Knowledge,” Los Angeles, Calif.

The Game of Life’s pulsing, pyrotechnic constellations are classic examples of emergent phenomena, introduced decades before that adjective became a buzzword.

Fifty years later, the misfortunes of 2020 are the stuff of memes. The biggest challenges facing us today are emergent: viruses leaping from species to species; the abrupt onset of wildfires and tropical storms as a consequence of a small rise in temperature; economies in which billions of free transactions lead to staggering concentrations of wealth; an internet that becomes more fraught with hazard each year

Looming behind it all is our collective vision of an artificial intelligence-fueled future that is certain to come with surprises, not all of them pleasant.

The name Conway chose — the Game of Life — frames his invention as a metaphor. But I’m not sure that even he anticipated how relevant Life would become, and that in 50 years we’d all be playing an emergent game of life and death.

In these exceptions, the needs of adults and children found recognition and accommodation. But many teens whose schools remain closed — which includes students at all public schools in San Francisco — were effectively told that they weren't allowed to see other human beings their age with whom they didn't already live.

The entire calculus behind the exceptions assumes a so-called typical teen experience — but it's disproportionately typical for teens who are white, middle- or upper-middle-class and male.

it is developmentally appropriate for teens to seek emotional support from romantic partners or friends, rather than caregivers.

But what parents and other authority figures need to understand is that teens are responding to a stymied developmental imperative.

Though the fear of missing out (or truly missing out) isn't a clinical diagnosis, we know that scrolling through social media feeds can leave teens both forlorn and anxious about where they fit in.

Still, the revision's monumental impact on teens seems to have been a happy coincidence — and teens' mental health cannot remain an afterthought.

Furthermore, policymakers should invest in teen mental health by subsidizing telehealth therapy and creating hotlines to manage short-of-crisis stress.

Our teens need the kind of forceful advocacy from adults that resulted in the reversal of playground closings in California.

Teens aren't cute little kids anymore, but they're just as vulnerable — and in this situation, arguably more so.

Uncertainty produces anxiety, but you can counter that, in part, by understanding what to expect on Election Day this year.

This year, Dr. Tillery observed, there’s a significant chance the presidential election will not be called on Tuesday night.

“Voters should get some comfort from knowing that we do have counting procedures and auditing procedures and voter notification procedures that would make it better for us to be calm and let those processes play out,”

Other analog activities can help you cope, too. “Anxious thoughts race by,” Dr. Stosny said, “and the faster they go, the less realistic they get.” Instead of dwelling on them, write them out longhand; this will slow down and moderate their frenetic pace. Next to each source of fear, write down how you’ll respond to it.

Be on the lookout for viral disinformation: Check the provenance of news articles or memes making polarizing political claims or calling the election before a mainstream news outlet has done so.

“Humans are quite resilient,” she said. “There’s a strong possibility that you will be able to cope.”

f a family member approaches you with anger, try to respond with compassion. Consider setting a time limit on your political discussions, Dr. Lee said, agreeing in advance to a fun, shared activity when your time is up.

If you’re feeling anxious or overwhelmed, or need to take time out of a challenging conversation, go for a walk or run, and try to spend at least 30 minutes outside.

68 percent of adults report finding the election to be a significant source of stress. This is due, at least in part, to the vitriol and name-calling exhibited by candidates,

“One of the things Covid has made abundantly clear in so many aspects of our life is that we have a lot of cracks in the system,”

“This is the first step in a long journey of really reimagining what America is going to look like and what America is going to be about,” Ms. Holland said. “That’s not going to end when the voting does.”

in the face of a publicly available birth certificate of the 44th President of the United States, there are diverse opinions regarding his birthplace.

But what actually determines whether someone will be persuaded by our argument or whether we will be ignored?

In one study, for example, my colleague Micha Edelson and I, together with others, recorded people’s brain activity while we exposed them to misinformation. A week later we invited everyone back to our lab and told them that the information we gave them before was randomly generated. About half the time our volunteers were able to correct the false beliefs we induced in them, but about half the time they continued believing misinformation.

This structure is called the amygdala and it is important for producing emotional arousal. We found that if the amygdala was activated when people were first exposed to misinformation, it was less likely we would be able to correct their judgments later.

good news was more likely to impact people’s beliefs than bad news. But that under stress, negative information, such as learning about unexpectedly high rates of disease and violent acts, is more likely to alter people’s beliefs.

Twitter is perfectly designed to engage our emotions because its features naturally call on our affective system; messages are fast, short and transferred within a social context.

information on Twitter (and other social platforms that use short and fast messages) is particularly likely to be evaluated based on emotional responses with little input from higher cognitive functions.

Science has shown that waiting just a couple of minutes before making judgments reduces the likelihood that they will be based solely on instinct.

people’s feelings, hopes and fears that play a central role in whether a piece of evidence will influence their beliefs.

One message they all had: You are stronger than you think you are, and everyone is able to adapt in ways they didn’t think possible.

there are a few techniques to help you along — 100-mile race not required.

There’s a pacing in living day to day, just as there’s pacing in climbing.

Training to become an elite endurance athlete means learning to embrace discomfort. Instead of hiding from pain, athletes must learn to work with it. A lot of that comes down to pacing

Similarly, as you muscle through an ongoing pandemic, you must look for ways to make peace with unknowns and new, uncomfortable realities. “When we think about the coronavirus, we are in it for the long run; so how do you pace yourself?”

She recommends thinking about your routines, practicing positive self-talk and focusing on processes instead of outcomes

You don’t know when the pandemic will end, but you can take control of your daily habits

“always have a little in reserve.”

Deplete your resources early and you’ll be in trouble. Focusing on day-to-day activities will pay off in the long run.

If you burn out all your mental energy in one day or week, you may find it more difficult to adapt when things don’t return to normal as quickly as you would hope.

Pace Yourself

“Don’t play all your cards at once and keep a little something in reserve.”

Create Mini-Goals

Sports psychologists frequently recommend creating mini milestones en route to a big goal. There are many steps on the path from base camp to a mountain’s summit. Likewise, there are smaller, more achievable milestones to reach and celebrate as you venture ahead into the unknown.

Focus on Something New

“I’m really good at breaking things down into small increments and setting micro-goals,” he said. How micro?

“I break things down to 10 seconds at a time,” Mr. Woltering continued. “You just have to be present in what you are doing and you have to know that it may not be the most fun — or super painful — now, but that could change in 10 seconds down the road.”

And it may not change quickly. Mr. Woltering said he has spent six-hour stretches counting to 10 over and over again. “You just keep moving and keep counting,” he said. “And you have to have faith that it will change at some point.”

Create Structure

“Part of expedition life is having a routine that you’re comfortable with. When I’m on expedition, I always start the day with a basin of warm water and soap. I wash my hands, face, neck and ears and get the sand out of my eyes,” he said. “It’s something that’s repeated that gets you a sense of comfort and normalcy.”

During the pandemic, he has found comfort and normalcy by getting outdoors, and climbing whenever possible to “run the engine.”

Dee Caffari, a British sailor and the first woman to sail solo, nonstop, around the world in both directions, said structure is imperative to fight back loneliness and monotony.

“In your day you need structure,” Ms. Caffari said. “You need to get up in the morning knowing you’re going to make something happen.”

“Setting goals that are controllable makes it easier to adapt,” Dr. Meijen said. “If you set goals that are controlled by other people, goals that aren’t realistic or are tough or boring, those are much harder to adapt to.”

When all else fails, look to something new: a new hobby, a new goal, a new experience

During a particularly hard patch of a competition, some athletes say they focus on a different sense, one that perhaps is not at the forefront of their mind when the pain sets in. A runner could note the smells around her and a climber could note the way his hair is blowing in the wind.

When athletes are injured, sports psychologists and coaches frequently encourage them to find a new activity to engage their mind and body. The key is to adapt, adapt and then adapt again.

“We all want mental toughness, it’s an important part of dealing with difficult things,”

“The current definition of mental toughness is the ability to pivot and to be nimble and flexible.”

“The next moment is always completely uncertain, and it’s always been that way,” Dr. Gervais said. But adapting, adjusting expectations and discovering new goals or hobbies can allow you to continue to build the muscle that is mental toughness.

Bottom line? “Optimism is an antidote to anxiety,”

The key achievement of middle age, according to Jaques, is to move beyond youthful idealism to what he called "contemplative pessimism" and "constructive resignation." He argued midlife was when we reach maturity by overcoming our denial of death and human destructiveness.Carl Jung presented a different view. He argued midlife was a time when previously suppressed aspects of the psyche might become integrated. Men could recover their unconscious feminine side, or anima, previously submerged during their youth, and women come alive to their hidden opposite, the animus.

Arguably there is no distinct midlife crisis, just crises that occur during midlife but might equally have occurred before or after.

But there may be something to it that's even more basic and biological. Chimpanzees and orangutans aren't known to suffer from existential dread, empty nest syndrome or job stress. And still, they show the same midlife dip in well-being as their human cousins.One study found chimps in their late 20s and orangutans in the mid-30s showed the lowest mood, the least pleasure in social activities, and the poorest capacity to achieve their goals. The researchers speculated this pattern might reflect age-related changes in brain structures associated with well-being that are similar between primate species.

Consider personality change, for example. One longitudinal study that followed thousands of Americans from age 41 to 50 found they became less neurotic and self-conscious with age. These personality changes were unrelated to the adults' experience of life adversity: resilience, not crisis, was the norm.

Another study that followed a sample of women from age 43 to 52 showed they tended to become less dependent and self-critical, and more confident, responsible and decisive, as they aged. These changes were unrelated to the women's menopausal status or empty nest experiences.

Even the self-reported midlife crises may have a silver lining. One study showed the more crises people reported, the more empathetic they were towards others. It is perhaps unsurprising older adults choose middle adulthood as the phase of life they most prefe

An intriguing thesis is that possessing a strong sense of life purpose provides us with that latent power to persevere and take action, even in the face of daunting odds and potential adversity. This is related to, though not identical to, the concept of resilience: the ability to bounce back from losses, failures, and disappointments

The S&P 500 closed Tuesday at the highest level in nearly three months. The Nasdaq has spiked 40% since March 23, fueled by the resilience of Big Tech, and is now within striking distance of all-time highs.

unprecedented stimulus from the Federal Reserve, and investors not wanting to miss out on monster returns once the economy recovers.

That means that while Main Street is still grappling with coronavirus, racial crisis and the impacts of both, Wall Street is doing just fine. Fed policy has allowed markets to decouple from economic reality.

Although the unrest was initially sparked by the killing of George Floyd, the continued broader economic discontent is an undercurrent.

that the American dream is not alive and well.

The divide between rich and poor was worsened by the Great Recession and its aftermath. The US government's response relied heavily on easy money from the Fed, rather than the kind of fiscal stimulus that can help lower-income Americans.

First, the coronavirus pandemic disproportionately hit poorer Americans, many of whom work in the hospitality and service sectors rocked by the pandemic. Nearly 40% of low-income workers lost their jobs in March alone, according to the Fed.

Twenge recognizes that her study shows only a correlation between screen use and "psychological well-being," which is measured using survey questions about self-esteem, life satisfaction and happiness. The surveys can't say whether screen time directly changes teens' mental health, the research states.

"I spent my career in technology. I wasn't prepared for its effect on my kids," philanthropist Melinda Gates, whose three children were also born after 1995, wrote August in the Washington Post. "Phones and apps aren't good or bad by themselves, but for adolescents who don't yet have the emotional tools to navigate life's complications and confusions, they can exacerbate the difficulties of growing up."

At the same time, she said, kids are learning on their devices and connecting in novel ways. "Marginalized groups such as gay and lesbian students (are) finding support they never had before through social networks," said Gates.

Other studies have explored the connection between social media and isolation and how "likes" activate the brain's reward center. Some analyses have found that moderate use of these technologies is "not intrinsically harmful" and can even improve social skills and develop resilience.

Resilience, including the ability to cope with stress and trauma, is another trait correlated with gratitude. Studies have showed that counting blessings was a factor in managing post-traumatic stress for Vietnam War veterans and an effective coping strategy for many after the 9/11 terrorist attacks. Other research shows that the more grateful you are, the more you are likely to exhibit patience and self-control. It can even be good for marriages and relationships: Couples good at exhibiting thankfulness tend to be "more committed and more likely to remain in their relationships over time." Our best selves, it seems, are our most grateful selves.

A gratitude journal need not be any more complicated than keeping a notebook by your bed and starting a nightly habit of jotting down who and what you were grateful for that day. Journaling was the standard method for some of the studies cited above, so this is a simple but effective option.

Roses, Thorns & Buds (or RTB, among its devotees) has been part of so many family dinners since my older daughter was 4 years old that I've forgotten where we first heard about it. It's quite simple: Everyone at the table takes turns sharing "roses," which are something positive and happy-making about their day; "thorns," which are the opposite of that; and "buds" for something we're looking forward to and we anticipate will be a rose. Sometimes, the family meal and sharing these things itself is a rose.

Happiness jars, a strategy popularized by "Eat, Pray, Love" author Elizabeth Gilbert, is something of a hybrid of gratitude journal and RTB. The idea is to write down on a slip of paper the happiest moment of the day and drop it in a jar. The advantage of doing it this way is that in moments of unhappiness, you can reach into the jar and be reminded of those moments, perhaps becoming grateful for them anew. Gilbert was struck by how many of her fans shared photos of their decorated happiness jars (see Pinterest if you need inspiration) and by how her happiest moments are "generally really common and quiet and unremarkable."

this distinction between mental and physical is not meaningful. Anxiety does not cause stomach aches; rather, feelings of anxiety and stomach aches are both ways that human brains make sense of physical discomfort

There is no such thing as a purely mental cause, because every mental experience has roots in the physical budgeting of your body. This is one reason physical actions like taking a deep breath, or getting more sleep, can be surprisingly helpful in addressing problems we traditionally view as psychological.

Your burden may feel lighter if you understand your discomfort as something physical. When an unpleasant thought pops into your head, like “I can’t take this craziness anymore,” ask yourself body-budgeting questions. “Did I get enough sleep last night? Am I dehydrated? Should I take a walk? Call a friend? Because I could use a deposit or two in my body budget.”

I’m not saying you can snap your fingers and dissolve deep misery, or sweep away depression with a change of perspective. I’m suggesting that it’s possible to acknowledge what your brain is actually doing and take some comfort from it

Your brain is not for thinking. Everything that it conjures, from thoughts to emotions to dreams, is in the service of body budgeting. This perspective, adopted judiciously, can be a source of resilience in challenging times.

I was relieved -- we wouldn't have to make what felt like an impossible decision -- but then I kept reading. My father had noted that he did not want to be supported by a ventilator or hooked up to a feeding tube for any length of time. He had been connected to both for nearly two weeks.

There was grief on her face, but also curiosity. What had finally gotten to her younger son, the one who so rarely showed emotion during his father's hospitalization?

I called the hospital and approved the DNR. They told me his status was still dire. I called my dad's closest friends and started preparing them for the worst.

My father's lungs showed no signs of progress. The double pneumonia they diagnosed days before was worsening. His kidneys were failing. Dialysis was required but would put a strain on his blood pressure, which was already dangerously low. There was a special form of dialysis designed for delicate situations like this -- continuous veno-venous hemofiltration -- but it wasn't available at Lawrence

The morning after I searched for my father's health directive and drafted his obituary, I woke up and tried to turn on my laptop. It wouldn't start. When it eventually booted up, it asked if I wanted to restore an unsaved document. No, I thought, let's see what happens today.

It was the same doctor as yesterday, the one who asked about the DNR. "Look, your dad is on a ventilator. That's a form of life support. He's experiencing kidney failure and requires dialysis. His situation is still very acute. He was in good health before the Covid, but his kidney, heart, and lungs are 69 years old. It's tough for them to recover. But the numbers from today are undeniably better than yesterday. There's been an improvement at almost every level. Your dad is a tough guy."

One of my close friends, a nurse practitioner, would help me understand all the terminology and its implications. He was treating Covid patients at an ICU upstate. At the end of our calls I'd ask him how he was doing. "We ran out of gowns," he told me one day. "My ICU is out of ventilators -- we're diverting people to Albany," he said another time.

"There's a difference between good intentions and good outcomes," I explained to her. She would wave me away and pick up. Inevitably the call would bring her tears. I stewed on the porch. My brother, uncle and I would spend hours trying to ease her mind and pacify her anxiety. Any inquiry or outreach was like sticking a finger in the open wound of her anguish.

"He's only improving," I told her, "because of the life-saving care you guys have given him. The whole city is in awe of you. They should have a parade for you down the Canyon of Heroes."

The nurses and doctors who took care of my father -- first for four days at NewYork-Presbyterian Lawrence Hospital, then for nearly a month at NewYork-Presbyterian/Columbia -- were always empathetic, straightforward and willing to trust me with complicated details.

About a week after writing -- then refusing to recover -- my father's obituary, his condition was continuing to improve.

I called my friend, the nurse practitioner, and gave him the latest update. He seemed upset. "You OK, dude?" "A nurse from my hospital died," he explained.

I wrote about my dad's volunteer work -- at the Special Olympics, at an organization he founded that helps police families with special needs, and at just about any Italian-American group that needed a lawyer. He was so proud of his Italian-American heritage. He loathed the mafioso caricatures and stereotypes found on TV -- he wrote countless op-eds attacking those -- but he revered the old-school virtues he associated with his Italian-American upbringing: loyalty, humility, hard work, dedication to family.

"Yesterday was a stumble, but we're getting back on course," I emailed the group. "We always knew this recovery wasn't going to be a straight line. It's important to remain resilient and optimistic even when there are temporary setbacks."

"Oh Lou, I've been waiting for your call. I have such good news. They are planning to extubate him tomorrow. They are going to take your father off the ventilator!" She was practically screaming with excitement. I was speechless.

I had been withholding certain information from my family and friends during this whole ordeal. My dad had developed a blood clot two weeks into his hospitalization. Clots are extremely dangerous, of course, but it was small and in a relatively manageable location.

I called my brother and told him about the plan to get my father off the ventilator. Since there were a number of contingencies, we debated telling my mother. She was living and dying with every update.

My father's breathing was labored on the morning they were planning to extubate. They delayed the procedure a day. That next morning, April 16, a doctor called. I was in the shower and rushed out to answer my cell. He said they were doing the extubation within the hour. What do we want to do if the extubation fails?

"It went as well as we could have hoped for," the doctor said. "His vitals are stable and he's breathing well. He's resting now." She explained that my father was disoriented and it probably wasn't a great idea to speak with him that day. Whatever, I thought, I'll speak with him when he gets home. He had been on a ventilator for 28 days.

I called the doctor later in the day. She told me my dad seemed distressed. He was trying to speak, but his vocal cords were too swollen. "It's so frustrating," she told me. "I don't know what he wants to tell me."

"Each facility has their own Covid rules," she explained. "I'll send you over a list." On the list was the nursing home where my grandfather had died several years before. My father had visited him every day.

I called the step-down unit where he had been the past three days. They transferred me to his nurse. "He's doing better, love. We took him off the pressor and his blood pressure is in a good range. His heart rate is good. He's breathing fine. The doctors decided he didn't need to go back to the ICU. He's ok."

"I've repeatedly said that recovery isn't a straight line. ... Yesterday we managed the roller coaster ride as a family. My brother, uncle and I were with my mother the entire day. We never lost hope or confidence in my dad's medical care and ultimate recovery. If there's a light at the end of the tunnel, it's a blinking one. Right now, it shines again."

I drove back to my mom's house. I scanned the block for my brother's car. He had not arrived. I parked. I have to wait for him and then tell my mother, brother and uncle all at once, right? Should I call my wife first? Should I call my dad's best friend?

I called my wife. I called my dad's best friend. I called the guys he grew up with. I called his former colleagues. I began every conversation the same way, "This is that call." I listened to each of them yell and cry and ask if I was serious. Then I said I had to make another call.

I wrote about my father's career. How he got his law degree at night school and became a prosecutor at the city, state, and federal level. How he convicted mobsters, drug dealers, and those who abused power.

Covid-19 was new and largely unstudied. Maybe one of these seemingly odd treatments would work.

He was a Covid patient for 31 days. It was a painful experience, but ultimately unimportant. It doesn't matter how a man dies. It matters how he lives.

When scientists ask: “How old do you feel, most of the time?” the answer tends to reflect the state of people’s physical and mental health. “This simple question seems to be particularly powerful,” says Antonio Terracciano, a professor of geriatrics at Florida State University College of Medicine in Tallahassee.Sign up for the Well NewsletterGet the best of Well, with the latest on health, fitness and nutrition.Sign Up* Captcha is incomplete.

Scientists are finding that people who feel younger than their chronological age are typically healthier and more psychologically resilient than those who feel older. They perform better on memory tasks and are at lower risk of cognitive decline.

If you’re over 40, chances are you feel younger than your driver’s license suggests. Some 80 percent of people do, according to Dr. Stephan. A small fraction of people — fewer than 10 percent — feel older.

At age 50, people may feel about five years, or 10 percent, younger, but by the time they’re 70 they may feel 15 percent or even 20 percent younger.

In a 2018 German study, investigators asked people in their 60s, 70s and early 80s how old they felt, then measured their walking speed in two settings. Participants walked 20 feet in the laboratory while being observed and timed. They also wore belts containing an accelerometer while out and about in their daily lives. Those who reported feeling younger tended to walk faster during the lab assessment. But feeling younger had no impact on their walking speed in real life.

Indeed, in cultures where elders are respected for their wisdom and experience, people don’t even understand the concept of subjective age, he said. When a graduate student of Dr. Weiss’s did research in Jordan, the people he spoke with “would say, ‘I’m 80. I don’t know what you mean by ‘How old do I feel?’”

As we age, we tend to become generally happier and more satisfied, said Dr. Tracey Gendron, a gerontologist at Virginia Commonwealth University who questions the whole notion of subjective age research

“Older age is a time that we can actually look forward to. People really just enjoy themselves more and are at peace with who they are. I would love for everyone to say their age at every year and celebrate it.”

For their study, they analyzed knowledge held by 57 indigenous communities in the Amazon basin, the Andes and the Chocó region to collate their knowledge of palm trees. The researchers then depicted the different palm species and their uses in graphical form in a network, from which they could identify the local and regional links between the knowledge of indigenous communities.

"In this context, cultural diversity is just as important as biological diversity," says Jordi Bascompte. "In particular, the simultaneous loss of plant species and cultural inheritance leads to a much faster disintegration of the indigenous knowledge network."

However, the irreplaceable knowledge that is gradually disappearing from indigenous communities is equally important for the service that an ecosystem provides."

The study also highlights the value of transdisciplinary collaboration between ecology and social science: "The relationship established between biological and cultural diversity can help strengthen the resilience of indigenous communities in the face of global change."

What could possibly be challenging about being a billionaire, you might ask. Well, what would it be like if you couldn’t trust those close to you? Or if you looked at any new person in your life with deep suspicion? I hear this from my clients all the time: “What do they want from me?”; or “How are they going to manipulate me?”; or “They are probably only friends with me because of my money.”

Too many of my clients want to indulge their children so “they never have to suffer what I had to suffer” while growing up.

If all your necessities and much more were covered for the rest of your life – you might struggle with a lack of meaning and ambition too. My clients are often bored with life and too many times this leads to them chasing the next high – chemically or otherwise – to fill that void.

Then there are the struggles with purpose – the depression that sets in when you feel like you have no reason to get out of bed. Why bother going to work when the business you have built or inherited runs itself without you now?

There is a perception that money can immunise you against mental-health problems when actually, I believe that wealth can make you – and the people closest to you – much more susceptible to them.

But the result is that they prevent their children from experiencing the very things that made them successful: sacrifice, hard work, overcoming failure and developing resilience. An over-indulged child develops into an entitled adult who has low self-confidence, low self-esteem, and a complete lack of grit.

These very wealthy children start out by going to elite boarding schools and move on to elite universities – developing a language and culture among their own kind. Rarely do they create friendships with non-wealthy people; this can lead to feelings of isolation and being trapped inside a very small bubble.

There are few people in the world to whom they can actually relate, which of course leads to a lack of empathy

Notice the awkwardness and lack of human connection and how dreadfully they treat each other. It’s fascinating and frightening. When one leads a life without consequences (for being rude to a waiter or cruel to a sibling, for example) there really is no reason to not do these things. After a while, it becomes normalised and accepted. Living a life without rules isn’t good for anyone.

The Bloomberg article cites a July meta-analysis in the medical journal Lancet, which found a tenuous link between higher temperatures and suicides and mental illness. But the study deems the collective evidence of “low certainty” owing to inconsistent study findings, methodologies, measured variables and definitions.

“climate change might not necessarily increase mental health issues because people might adapt over time, meaning that higher temperatures could become normal and not be experienced as anomalous or extreme.”

yes. Before the media began reporting on putative temperature records—the scientific evidence for which is also weak—heat waves were treated as a normal part of summer. Uncomfortable, but figuratively nothing to sweat about.

according to a World Health Organization report last year, the very “awareness of climate change and extreme weather events and their impacts” may lead to a host of ills, including strained social relationships, anxiety, depression, intimate-partner violence, helplessness, suicidal behavior and alcohol and substance abuse.

“First and foremost, it is imperative that adults understand that youth climate anxiety (also referred to as eco-anxiety, solastalgia, eco-guilt or ecological grief) is an emotionally and cognitively functional response to real existential threats,” a May 10 editorial in the journal Nature explained. “Although feelings of powerlessness, grief and fear can be profoundly disruptive—particularly for young people unaccustomed to the depth and complexity of such feelings—it is important to acknowledge that this response is a rational one.”

Forty-five percent claimed they were so worried that they struggled to function on a daily basis, the definition of an anxiety disorder.

A study in 2021 of 16- to 25-year-olds in 10 countries including the U.S. reported that 59% were very or extremely worried about climate change, and 84% were at least moderately worried

These anxieties are no more rational than the threats from climate change are existential.

A more apt term for such fear is climate hypochondria.

The New Yorker magazine earlier this month published a 4,400-word piece titled “What to Do With Climate Emotions” by Jia Tolentino, a woman in the throes of such neurosis

Ms. Tolentino goes on to describe how climate therapists can help patients cope. “The goal is not to resolve the intrusive feeling and put it away” but, as one therapist advises her, “to aim for a middle ground of sustainable distress.” Even the climate left’s despair must be “sustainable.”

there’s nothing normal about climate anxiety, despite the left’s claims to the contrary.

Progressives may even use climate change to displace their other anxieties—for instance, about having children

Displacement is a maladaptive mechanism by which people redirect negative emotions from one thing to another

Climate hypochondriacs deserve to be treated with compassion, much like anyone who suffers from mental illness. They shouldn’t, however, expect everyone else to enable their neuroses.
