How stress weathers our bodies, causing illness and premature aging - Washington Post - 1 views

  • Stress is a physiological reaction that is part of the body’s innate programming to protect against external threats.
  • When danger appears, an alarm goes off in the brain, activating the body’s sympathetic nervous system — the fight-or-flight system. The hypothalamic-pituitary-adrenal axis is activated. Hormones, such as epinephrine and cortisol, flood the bloodstream from the adrenal glands.
  • The heart beats faster. Breathing quickens. Blood vessels dilate. More oxygen reaches large muscles. Blood pressure and glucose levels rise. The immune system’s inflammatory response activates, promoting quick healing.

  • Life brings an accumulation of unremitting stress, especially for those subjected to inequity — and not just from immediate and chronic threats. Even the anticipation of those menaces causes persistent damage.
  • The body produces too much cortisol and other stress hormones, straining to bring itself back to normal. Eventually, the body’s machinery malfunctions.
  • The constant strain — the chronic sources of stress — resets what is “normal,” and the body begins to change.
  • t is the repeated triggering of this process year after year — the persistence of striving to overcome barriers — that leads to poor health.
  • Blood pressure remains high. Inflammation turns chronic. In the arteries, plaque forms, causing the linings of blood vessels to thicken and stiffen. That forces the heart to work harder. It doesn’t stop there. Other organs begin to fail.
  • , that people’s varied life experiences affect their health by wearing down their bodies. And second, she said: “People are not just passive victims of these horrible exposures. They withstand them. They struggle against them. These are people who weather storms.”
  • It isn’t just living in an unequal society that makes people sick. It’s the day-in, day-out effort of trying to be equal that wears bodies down.
  • Weathering doesn’t start in middle age.
  • It begins in the womb. Cortisol released into a pregnant person’s bloodstream crosses the placenta, which helps explain why a disproportionate number of babies born to parents who live in impoverished communities or who experience the constant scorn of discrimination are preterm and too small.
  • The argument weathering is trying to make is these are things we can change, but we have to understand them in their complexity,” Geronimus said. “This has to be a societal project, not the new app on your phone that will remind you to take deep breaths when you’re feeling stress.”

Why Silence Is So Good For Your Brain | Huffington Post - 0 views

  • We live in a loud and distracting world, where silence is increasingly difficult to come by — and that may be negatively affecting our health.

  • How many moments each day do you spend in total silence?
  • Silence relieves stress and tension.
  • noise pollution has been found to lead to high blood pressure and heart attacks, as well as impairing hearing and overall health. Loud noises raise stress levels by activating the brain’s amygdala and causing the release of the stress hormone cortisol
  • In our everyday lives, sensory input is being thrown at us from every angle. When we can finally get away from these sonic disruptions, our brains’ attention centers have the opportunity to restore themselves.
  • The ceaseless attentional demands of modern life put a significant burden on the prefrontal cortex of the brain, which is involved in high-order thinking, decision-making and problem-solving.
  • Silence can quite literally grow the brain.

Joe Biden's tears show politics doesn't have to be macho | Angelina Chapin | Opinion | The Guardian - 0 views

  • Too many men still think a woman who cries is acting hysterical. For some baffling reason, punching a hole in the wall or another person in the face is a more culturally acceptable way to release pain than sobbing into a pillow. And politics is no different. Anger makes you a strong candidate while sadness makes you frail. The result is that many female politicians swallow their emotions in an effort to appear tough.
  • The stereotype that women are overly emotional, hormonal beings who are unfit to lead still exists. Powerful men like Obama and Biden who embrace their feelings on a public stage help to combat the ridiculous political stigma against sensitivity. Every time these political powerhouses become misty-eyed, they send the message that having human feelings doesn’t equal incompetence.
  • By being the kind of men who are unafraid to openly love one another and cry in public, they have sent a message to aspiring female politicians that being human doesn’t come with a penalty.

The decline effect and the scientific method : The New Yorker - 3 views

  • The test of replicability, as it’s known, is the foundation of modern research. Replicability is how the community enforces itself. It’s a safeguard for the creep of subjectivity. Most of the time, scientists know what results they want, and that can influence the results they get. The premise of replicability is that the scientific community can correct for these flaws.
  • But now all sorts of well-established, multiply confirmed findings have started to look increasingly uncertain. It’s as if our facts were losing their truth: claims that have been enshrined in textbooks are suddenly unprovable.
  • This phenomenon doesn’t yet have an official name, but it’s occurring across a wide range of fields, from psychology to ecology.
  • ...39 more annotations...
  • If replication is what separates the rigor of science from the squishiness of pseudoscience, where do we put all these rigorously validated findings that can no longer be proved? Which results should we believe?
  • Schooler demonstrated that subjects shown a face and asked to describe it were much less likely to recognize the face when shown it later than those who had simply looked at it. Schooler called the phenomenon “verbal overshadowing.”
  • The most likely explanation for the decline is an obvious one: regression to the mean. As the experiment is repeated, that is, an early statistical fluke gets cancelled out. The extrasensory powers of Schooler’s subjects didn’t decline—they were simply an illusion that vanished over time.
  • yet Schooler has noticed that many of the data sets that end up declining seem statistically solid—that is, they contain enough data that any regression to the mean shouldn’t be dramatic. “These are the results that pass all the tests,” he says. “The odds of them being random are typically quite remote, like one in a million. This means that the decline effect should almost never happen. But it happens all the time!
  • this is why Schooler believes that the decline effect deserves more attention: its ubiquity seems to violate the laws of statistics
  • In 2001, Michael Jennions, a biologist at the Australian National University, set out to analyze “temporal trends” across a wide range of subjects in ecology and evolutionary biology. He looked at hundreds of papers and forty-four meta-analyses (that is, statistical syntheses of related studies), and discovered a consistent decline effect over time, as many of the theories seemed to fade into irrelevance.
  • Jennions admits that his findings are troubling, but expresses a reluctance to talk about them
  • publicly. “This is a very sensitive issue for scientists,” he says. “You know, we’re supposed to be dealing with hard facts, the stuff that’s supposed to stand the test of time. But when you see these trends you become a little more skeptical of things.”
  • While publication bias almost certainly plays a role in the decline effect, it remains an incomplete explanation. For one thing, it fails to account for the initial prevalence of positive results among studies that never even get submitted to journals. It also fails to explain the experience of people like Schooler, who have been unable to replicate their initial data despite their best efforts.
  • Jennions, similarly, argues that the decline effect is largely a product of publication bias, or the tendency of scientists and scientific journals to prefer positive data over null results, which is what happens when no effect is found. The bias was first identified by the statistician Theodore Sterling, in 1959, after he noticed that ninety-seven per cent of all published psychological studies with statistically significant data found the effect they were looking for
  • Sterling saw that if ninety-seven per cent of psychology studies were proving their hypotheses, either psychologists were extraordinarily lucky or they published only the outcomes of successful experiments.
  • One of his most cited papers has a deliberately provocative title: “Why Most Published Research Findings Are False.”
  • suspects that an equally significant issue is the selective reporting of results—the data that scientists choose to document in the first place. Palmer’s most convincing evidence relies on a statistical tool known as a funnel graph. When a large number of studies have been done on a single subject, the data should follow a pattern: studies with a large sample size should all cluster around a common value—the true result—whereas those with a smaller sample size should exhibit a random scattering, since they’re subject to greater sampling error. This pattern gives the graph its name, since the distribution resembles a funnel.
  • after Palmer plotted every study of fluctuating asymmetry, he noticed that the distribution of results with smaller sample sizes wasn’t random at all but instead skewed heavily toward positive results. Palmer has since documented a similar problem in several other contested subject areas. “Once I realized that selective reporting is everywhere in science, I got quite depressed,” Palmer told me. “As a researcher, you’re always aware that there might be some nonrandom patterns, but I had no idea how widespread it is.”
  • Palmer summarized the impact of selective reporting on his field: “We cannot escape the troubling conclusion that some—perhaps many—cherished generalities are at best exaggerated in their biological significance and at worst a collective illusion nurtured by strong a-priori beliefs often repeated.”
  • Palmer emphasizes that selective reporting is not the same as scientific fraud. Rather, the problem seems to be one of subtle omissions and unconscious misperceptions, as researchers struggle to make sense of their results. Stephen Jay Gould referred to this as the “sho
  • horning” process.
  • “A lot of scientific measurement is really hard,” Simmons told me. “If you’re talking about fluctuating asymmetry, then it’s a matter of minuscule differences between the right and left sides of an animal. It’s millimetres of a tail feather. And so maybe a researcher knows that he’s measuring a good male”—an animal that has successfully mated—“and he knows that it’s supposed to be symmetrical. Well, that act of measurement is going to be vulnerable to all sorts of perception biases. That’s not a cynical statement. That’s just the way human beings work.”
  • For Simmons, the steep rise and slow fall of fluctuating asymmetry is a clear example of a scientific paradigm, one of those intellectual fads that both guide and constrain research: after a new paradigm is proposed, the peer-review process is tilted toward positive results. But then, after a few years, the academic incentives shift—the paradigm has become entrenched—so that the most notable results are now those that disprove the theory.
  • John Ioannidis, an epidemiologist at Stanford University, argues that such distortions are a serious issue in biomedical research. “These exaggerations are why the decline has become so common,” he says. “It’d be really great if the initial studies gave us an accurate summary of things. But they don’t. And so what happens is we waste a lot of money treating millions of patients and doing lots of follow-up studies on other themes based on results that are misleading.”
  • In 2005, Ioannidis published an article in the Journal of the American Medical Association that looked at the forty-nine most cited clinical-research studies in three major medical journals.
  • the data Ioannidis found were disturbing: of the thirty-four claims that had been subject to replication, forty-one per cent had either been directly contradicted or had their effect sizes significantly downgraded.
  • the most troubling fact emerged when he looked at the test of replication: out of four hundred and thirty-two claims, only a single one was consistently replicable. “This doesn’t mean that none of these claims will turn out to be true,” he says. “But, given that most of them were done badly, I wouldn’t hold my breath.”
  • According to Ioannidis, the main problem is that too many researchers engage in what he calls “significance chasing,” or finding ways to interpret the data so that it passes the statistical test of significance—the ninety-five-per-cent boundary invented by Ronald Fisher.
  • One of the classic examples of selective reporting concerns the testing of acupuncture in different countries. While acupuncture is widely accepted as a medical treatment in various Asian countries, its use is much more contested in the West. These cultural differences have profoundly influenced the results of clinical trials.
  • The problem of selective reporting is rooted in a fundamental cognitive flaw, which is that we like proving ourselves right and hate being wrong.
  • “It feels good to validate a hypothesis,” Ioannidis said. “It feels even better when you’ve got a financial interest in the idea or your career depends upon it. And that’s why, even after a claim has been systematically disproven”—he cites, for instance, the early work on hormone replacement therapy, or claims involving various vitamins—“you still see some stubborn researchers citing the first few studies
  • That’s why Schooler argues that scientists need to become more rigorous about data collection before they publish. “We’re wasting too much time chasing after bad studies and underpowered experiments,”
  • The current “obsession” with replicability distracts from the real problem, which is faulty design.
  • “Every researcher should have to spell out, in advance, how many subjects they’re going to use, and what exactly they’re testing, and what constitutes a sufficient level of proof. We have the tools to be much more transparent about our experiments.”
  • Schooler recommends the establishment of an open-source database, in which researchers are required to outline their planned investigations and document all their results. “I think this would provide a huge increase in access to scientific work and give us a much better way to judge the quality of an experiment,”
  • scientific research will always be shadowed by a force that can’t be curbed, only contained: sheer randomness. Although little research has been done on the experimental dangers of chance and happenstance, the research that exists isn’t encouraging.
  • The disturbing implication of the Crabbe study is that a lot of extraordinary scientific data are nothing but noise. The hyperactivity of those coked-up Edmonton mice wasn’t an interesting new fact—it was a meaningless outlier, a by-product of invisible variables we don’t understand.
  • The problem, of course, is that such dramatic findings are also the most likely to get published in prestigious journals, since the data are both statistically significant and entirely unexpected
  • This suggests that the decline effect is actually a decline of illusion. While Karl Popper imagined falsification occurring with a single, definitive experiment—Galileo refuted Aristotelian mechanics in an afternoon—the process turns out to be much messier than that.
  • Many scientific theories continue to be considered true even after failing numerous experimental tests.
  • Even the law of gravity hasn’t always been perfect at predicting real-world phenomena. (In one test, physicists measuring gravity by means of deep boreholes in the Nevada desert found a two-and-a-half-per-cent discrepancy between the theoretical predictions and the actual data.)
  • Such anomalies demonstrate the slipperiness of empiricism. Although many scientific ideas generate conflicting results and suffer from falling effect sizes, they continue to get cited in the textbooks and drive standard medical practice. Why? Because these ideas seem true. Because they make sense. Because we can’t bear to let them go. And this is why the decline effect is so troubling. Not because it reveals the human fallibility of science, in which data are tweaked and beliefs shape perceptions. (Such shortcomings aren’t surprising, at least for scientists.) And not because it reveals that many of our most exciting theories are fleeting fads and will soon be rejected. (That idea has been around since Thomas Kuhn.)
  • The decline effect is troubling because it reminds us how difficult it is to prove anything. We like to pretend that our experiments define the truth for us. But that’s often not the case. Just because an idea is true doesn’t mean it can be proved. And just because an idea can be proved doesn’t mean it’s true. When the experiments are done, we still have to choose what to believe. ♦

Does Thinking Really Hard Burn More Calories?: Scientific American - 0 views

  • Just as vigorous exercise tires our bodies, intellectual exertion should drain the brain. What the latest science reveals, however, is that the popular notion of mental exhaustion is too simplistic. The brain continuously slurps up huge amounts of energy for an organ of its size, regardless of whether we are tackling integral calculus or clicking through the week's top 10 LOLcats. Although firing neurons summon extra blood, oxygen and glucose, any local increases in energy consumption are tiny compared with the brain's gluttonous baseline intake. So, in most cases, short periods of additional mental effort require a little more brainpower than usual, but not much more.
  • something must explain the feeling of mental exhaustion, even if its physiology differs from physical fatigue. Simply believing that our brains have expended a lot of effort might be enough to make us lethargic.
  • a typical adult human brain runs on around 12 watts—a fifth of the power required by a standard 60 watt lightbulb. Compared with most other organs, the brain is greedy; pitted against man-made electronics, it is astoundingly efficient. IBM's Watson, the supercomputer that defeated Jeopardy! champions, depends on ninety IBM Power 750 servers, each of which requires around one thousand watts.
  • ...4 more annotations...
  • people routinely enjoy intellectually invigorating activities without suffering mental exhaustion.
  • Such fatigue seems much more likely to follow sustained mental effort that we do not seek for pleasure—such as the obligatory SAT—especially when we expect that the ordeal will drain our brains. If we think an exam or puzzle will be difficult, it often will be.
  • Studies have shown that something similar happens when people exercise and play sports: a large component of physical exhaustion is in our heads. In related research, volunteers that cycled on an exercise bike following a 90-minute computerized test of sustained attention quit pedaling from exhaustion sooner than participants that watched emotionally neutral documentaries before exercising
  • In the specific case of the SAT, something beyond pure mental effort likely contributes to post-exam stupor: stress. After all, the brain does not function in a vacuum. Other organs burn up energy, too. Taking an exam that partially determines where one will spend the next four years is nerve-racking enough to send stress hormones swimming through the blood stream, induce sweating, quicken heart rates and encourage fidgeting and contorted body postures. The SAT and similar trials are not just mentally taxing—they are physically exhausting, too.

Why I quit Facebook - NYPOST.com - 0 views

  • I quickly realize the reality of my situation: The world does not revolve around me. My friends all have other friends. Every minute that I spend navigating the Facebook universe, I am shrinking
  • Every status and post seems to be saying “I’m here! Tell me that I’m somebody!” Hundreds of kids are selling their identities — like livestock at a market — for a couple of comments and “likes.”
  • Being constantly informed that you make up just a small portion of another person’s life erodes the feeling that you are at all meaningful to them. Adolescence, to begin with, is a time of awful social anxiety. Now a website exists that exacerbates your most irrational social fears to the point of paranoia. Instead of just a private hormonal case of nerves, this is a massive, corporate crowd-sourced paranoia that a huge economic sector is encouraging us to take part in.On Facebook, I saw how I was taking time away from being with my real friends to feel bad about all the other people who were hardly even part of my life.

Why Do Some Brains Enjoy Fear? - Allegra Ringo - The Atlantic - 1 views

  • One of the most interesting things about studying fear is looking at the social constructions of fear, and learned fears versus those fears that appear to be more innate, or even genetic
  • Through fear conditioning (connecting a neutral stimulus with a negative consequence) we can link pretty much anything to a fear response.
  • So we know that we can learn to fear, and this means our socialization and the society in which we are raised is going to have a lot to do with what we find scary.
  • ...7 more annotations...
  • This speaks to the fact that things that violate the laws of nature are terrifying. And really anything that doesn’t make sense or causes us some sort of dissonance, whether it is cognitive or aesthetic, is going to be scary (axe-wielding animals, masked faces, contorted bodies).
  • Humans are obsessed with death; we simply have a hard time wrapping our mind around what happens when we die.
  • Humans have been scaring themselves and each other since the birth of the species, through all kinds of methods like storytelling, jumping off cliffs, and popping out to startle each other from the recesses of some dark cave.
  • to build group unity, to prepare kids for life in the scary world, and, of course, to control behavior.
  • These scary stories provided, and continue to deliver, intrigue, exhilaration, and a jolt of excitement to our lives.
  • One of the reasons people love Halloween is because it produces strong emotional responses, and those responses work to build stronger relationships and memories. When we’re happy, or afraid, we’re releasing powerful hormones, like oxcytocin, that are working to make these moments stick in our brain. So we’re going to remember the people we’re with. If it was a good experience, then we’ll remember them fondly and feel close to them, more so than if we were to meet them during some neutral unexciting event.
  • We’re social and emotional beings. We need each other in times of stress, so the fact that our bodies have evolved to make sure we feel close to those we are with when afraid makes sense.

It's Not Just About Bad Choices - NYTimes.com - 0 views

  • WHENEVER I write about people who are struggling, I hear from readers who say something like: Folks need to stop whining and get a job. It’s all about personal responsibility.

  • Self-destructive behaviors — dropping out of school, joining a gang, taking drugs, bearing children when one isn’t ready — compound poverty.
  • Yet scholars are also learning to understand the roots of these behaviors, and they’re far more complicated than the conservative narrative of human weakness.
  • For starters, there is growing evidence that poverty and mental health problems are linked in complex, reinforcing ways
  • If you’re battling mental health problems, or grow up with traumas like domestic violence (or seeing your brother shot dead), you’re more likely to have trouble in school, to self-medicate with drugs or alcohol, to have trouble in relationships.
  • A second line of research has shown that economic stress robs us of cognitive bandwidth.
  • Worrying about bills, food or other problems, leaves less capacity to think ahead or to exert self-discipline. So, poverty imposes a mental tax.
  • It turns out that when people have elevated levels of cortisol, a stress hormone, they are less willing to delay gratification.
  • it’s circumstances that can land you in a situation where it’s really hard to make a good decision because you’re so stressed out. And the ones you get wrong matter much more, because there’s less slack to play with.”
  • That emphasis on personal responsibility is part of the 12-step program to confront alcoholism or drug addiction, and it may be useful for people like Jackson. But for society to place the blame entirely on the individual seems to me a cop-out.
  • Let’s also remember, though, that today we have randomized trials — the gold standard of evidence — showing that certain social programs make self-destructive behaviors less common.
  • as long as we’re talking about personal irresponsibility, let’s also examine our own. Don’t we have a collective responsibility to provide more of a fair start in life to all, so that children aren’t propelled toward bad choices?

How Walking in Nature Changes the Brain - The New York Times - 0 views

  • A walk in the park may soothe the mind and, in the process, change the workings of our brains in ways that improve our mental health, according to an interesting new study
  • Various studies have found that urban dwellers with little access to green spaces have a higher incidence of psychological problems than people living near parks and that city dwellers who visit natural environments have lower levels of stress hormones immediately afterward than people who have not recently been outside.
  • Mr. Bratman and his collaborators decided to closely scrutinize what effect a walk might have on a person’s tendency to brood.
  • ...7 more annotations...
  • Brooding, which is known among cognitive scientists as morbid rumination, is a mental state familiar to most of us, in which we can’t seem to stop chewing over the ways in which things are wrong with ourselves and our lives. This broken-record fretting is not healthy or helpful. It can be a precursor to depression and is disproportionately common among city dwellers compared with people living outside urban areas
  • such rumination also is strongly associated with increased activity in a portion of the brain known as the subgenual prefrontal cortex.
  • the scientists randomly assigned half of the volunteers to walk for 90 minutes through a leafy, quiet, parklike portion of the Stanford campus or next to a loud, hectic, multi-lane highway in Palo Alto. The volunteers were not allowed to have companions or listen to music. They were allowed to walk at their own pace.
  • walking along the highway had not soothed people’s minds. Blood flow to their subgenual prefrontal cortex was still high and their broodiness scores were unchanged.

They were not dwelling on the negative aspects of their lives as much as they had been before the walk. They also had less blood flow to the subgenual prefrontal cortex. That portion of their brains were quieter.
  • These results “strongly suggest that getting out into natural environments” could be an easy and almost immediate way to improve moods for city dwellers, Mr. Bratman said.
  • many questions remain, he said, including how much time in nature is sufficient or ideal for our mental health, as well as what aspects of the natural world are most soothing. Is it the greenery, quiet, sunniness, loamy smells, all of those, or something else that lifts our moods? Do we need to be walking or otherwise physically active outside to gain the fullest psychological benefits? Should we be alone or could companionship amplify mood enhancements? “There’s a tremendous amount of study that still needs to be done,” Mr. Bratman said.

What Eating 40 Teaspoons of Sugar a Day Can Do to You - The New York Times - 0 views

  • In “That Sugar Film,” which first had its debut in Australia this year, Mr. Gameau gives up his normal diet of fresh foods for two months to see what happens when he shifts to eating a diet containing 40 teaspoons of sugar daily, the amount consumed by the average Australian
  • The twist is that Mr. Gameau avoids soda, ice cream, candy and other obvious sources of sugar. Instead, he consumes foods commonly perceived as “healthy” that are frequently loaded with added sugars, like low-fat yogurt, fruit juice, health bars and cereal.
  • Mr. Gameau finds that his health and waistline quickly spiral out of control.
  • ...6 more annotations...
  • These are the foods with flowers and bees and sunsets on their labels. That’s the whole point of the film. If I had been eating chocolate doughnuts and soft drinks, we know what would have happened to me. But the fact that this happened when I was following the low-fat diet that we’ve all been prescribed for 35 years – that was surprising.
  • What was your diet like before the start of the film? A. I kept away from processed foods as much as I could. I’d have eggs for breakfast. I’d eat healthy fats like avocado, and I’d snack on nuts and a little cheese. I’d have lots of fruits and vegetables and protein sources like fish. I just tried to eat real foods, and I kept it really simple.
  • How did it change during the film? A. I swapped all that for the refined carbohydrates. Cereals, low-fat yogurts and apple juice would be my breakfast instead of eggs and avocado. And lunch would be pasta with pasta sauce, or some vegetables or fish with a teriyaki sauce or some kind of dressing that had added sugars in it.
  • My calorie intake didn’t change. What I was eating before – the avocados and nuts and other foods – are high in calories. So I kept a similar calorie intake. But on the diet with all the added sugars, I was snacking a lot more. I just never felt full, and it was affecting my moods. What I learned was that I was triggering insulin and all sorts of hormones that were trapping fat in my body.
  • I don’t think we should ever demonize one nutrient. But when that one single nutrient is now in 80 percent of all foods, we do need to look at it. This is not just about putting sugar in your tea or coffee. It’s pervaded our entire food supply, and people are having far too much of it. And I think most of those people don’t realize how much they’re having.
  • When I went back to just drinking water and eating food again, the weight dropped, and all my symptoms went away. I think we just need to simplify things. Stick to the perimeter of the supermarket where all the fresh foods are. Buy real foods as much as you can.

Forever Young? For Bob Dylan, In Some Ways, Yes. - NYTimes.com - 1 views

  • Fourteen is a formative age, especially for people growing up in social contexts framed by pop culture. You’re in the ninth grade, confronting the tyrannies of sex and adulthood, struggling to figure out what kind of adult you’d like to be, and you turn to the cultural products most important in your day as sources of cool — the capital of young life.
  • “Fourteen is a sort of magic age for the development of musical tastes,”
  • “Pubertal growth hormones make everything we’re experiencing, including music, seem very important. We’re just reaching a point in our cognitive development when we’re developing our own tastes. And musical tastes become a badge of identity.”
  •  
    I had never really considered how formative and pivotal these early years of our lives are. I also find it quite interesting that the media and our general environment can play such a role in our development, sometimes inspiring adolescents to find their passions so early in life. Makes you think about the effects our current genres of popular music are having on our ninth graders (Oh dear lord, I don't even want to think about it).

  • many questions remain, he said, including how much time in nature is sufficient or ideal for our mental health, as well as what aspects of the natural world are most soothing. Is it the greenery, quiet, sunniness, loamy smells, all of those, or something else that lifts our moods?

Buying begets buying: how stuff has consumed the average American's life | Life and style | The Guardian - 0 views

  • Our addiction to consuming things is a vicious cycle, and buying a bigger house to store it all isn’t the answer.
  • personal storage industry rakes in $22bn each year, and it’s only getting bigger. Why?
  • So, if our houses have tripled in size while the number of people living in them has shrunk, what, exactly, are we doing with all of this extra space? And why the billions of dollars tossed to an industry that was virtually nonexistent a generation or two ago?
  • ...10 more annotations...
  • because of our stuff. What kind of stuff? Who cares!
  • don’t do anything but take up space and look pretty for a season or two before being replaced by other, newer things – equally pretty and equally useless.
  • if you have more stuff than you do space to easily store it, your life will be spent a slave to your possessions.
  • We shop because we’re bored, anxious, depressed or angry, and we make the mistake of buying material goods and thinking they are treats which will fill the hole, soothe the wound, make us feel better. The problem is, they’re not treats, they’re responsibilities and what we own very quickly begins to own us.
  • when you buy something, you’re also taking on the task of disposing of it (responsibly or not) when you’re done with it. Our addiction to consumption is a vicious one, and it’s stressing us out.
  • A study published by UCLA showed that women’s stress hormones peaked during the times they were dealing with their possessions and material goods.
  • Our current solution to having too much stuff is as short-sighted as it is ineffective: when we run out of space, we simply buy a bigger house.
  • So if bigger homes aren’t the solution, what is? I suggest heading in the exact opposite direction: deliberately choose a life with less. Buy less and instantly you have less to store; you use less space. Eventually you can work less to pay for all of this stuff. Soon you will stress less too and, above all, your life will involve less waste.
  • wondering where to begin? Don’t. You know exactly where this journey starts. It starts with the stuff that makes you feel guilty, stressed or overwhelmed when you look at it.
  • Because when it comes to stuff, I promise you, you don’t need more labels or better systems or complicated Pinterest tutorials – all you need is less.

The Virtues of Reality - The New York Times - 1 views

  • SINCE the 1990s, we’ve seen two broad social changes that few observers would have expected to happen together.
  • First, youth culture has become less violent, less promiscuous and more responsible. American childhood is safer than ever before. Teenagers drink and smoke less than previous generations. The millennial generation has fewer sexual partners than its parents, and the teen birthrate has traced a two-decade decline. Violent crime — a young person’s temptation — fell for 25 years before the recent post-Ferguson homicide spike. Young people are half as likely to have been in a fight than a generation ago. Teen suicides, binge drinking, hard drug use — all are down.
  • But over the same period, adulthood has become less responsible, less obviously adult. For the first time in over a century, more 20-somethings live with their parents than in any other arrangement. The marriage rate is way down, and despite a high out-of-wedlock birthrate American fertility just hit an all-time low. More and more prime-age workers are dropping out of the work force — men especially, and younger men more so than older men, though female work force participation has dipped as well.
  • ...6 more annotations...
  • I want to advance a technology-driven hypothesis: This mix of youthful safety and adult immaturity may be a feature of life in a society increasingly shaped by the internet’s virtual realities.
  • It is easy to see how online culture would make adolescent life less dangerous. Pornography to take the edge off teenage sexual appetite. Video games instead of fisticuffs or contact sports as an outlet for hormonal aggression. (Once it was feared that porn and violent media would encourage real-world aggression; instead they seem to be replacing it.) Sexting and selfie-enabled masturbation as a safer alternative to hooking up. Online hangouts instead of keggers in the field. More texting and driving, but less driving — one of the most dangerous teen activities — overall.
  • The question is whether this substitution is habit-forming and soul-shaping, and whether it extends beyond dangerous teen behavior to include things essential to long-term human flourishing — marriage, work, family, all that old-fashioned “meatspace” stuff.
  • It wasn’t so long ago that people worried about a digital divide, in which online access would be a luxury good that left the bottom half behind. But if anything, the virtual world looks more like an opiate for the masses
  • trends in the marketplace — ever-more-customized pornography, virtual realities that feel more and more immersive, devices and apps customized for addictive behavior — seem likely to overwhelm most attempts to enjoy the virtual only within limits.
  • Patricia Snow (yes, even columnists have mothers), in an essay for First Things earlier this year, suggested that any effective resistance to virtual reality’s encroachments would need to be moral and religious, not just pragmatic and managerial

The Triumph of Obama's Long Game - 0 views

  • Speaking of ideology versus reality, there is, it seems to me, a parallel on the left. That is the current attempt to deny the profound natural differences between men and women, and to assert, with a straight and usually angry face, that gender is in no way rooted in sex, and that sex is in no way rooted in biology.
  • This unscientific product of misandrist feminism and confused transgenderism is striding through the culture, and close to no one in the elite is prepared to resist it.
  • And so we have the establishment of gender-neutral birth certificates in Canada; and, in England, that lovely old phrase, “Ladies and Gentlemen,” is being removed from announcements on the Tube
  • ...20 more annotations...
  • We have dozens of new pronouns in colleges (for all those genders that have suddenly sprung into existence), and biological males competing in all-female high-school athletic teams (guess who wins at track).
  • Worse, we have constant admonitions against those who actually conform, as most human beings always have, to the general gender rule.
  • We have gone from rightly defending the minority to wrongly problematizing the majority. It should surprise no one that, at some point, the majority will find all of this, as Josh Barro recently explained, “annoying.”
  • I say this as someone happily in the minority — and who believes strongly in the right to subvert or adapt traditional gender roles.
  • But you can’t subvert something that you simultaneously argue doesn’t exist.
  • the core contradiction of ideological transgenderism. By severing the link between sex and gender completely, it abolishes the core natural framework without which the transgender experience makes no sense at all.
  • It’s also a subtle, if unintentional, attack on homosexuality. Most homosexuals are strongly attached to their own gender and attracted to traditional, natural expressions of it. That’s what makes us gay, for heaven’s sake. And that’s one reason the entire notion of a common “LGBT” identity is so misleading. How can a single identity comprise both the abolition of gender and at the same time its celebration?
  • Exceptions, in other words, need a rule to exist. Abolish gender’s roots in biology and sex — and you abolish gay people and transgender people as well.
  • Yes, there’s a range of gender expression among those of the same sex. But it’s still tethered among most to the forces of chromosomes and hormones that make us irreducibly male and female. Nature can be interpreted; it can even be played with; but it cannot be abolished. After all, how can you be “queer” if there is no such thing as “normal”?
  • Transgender people exist and should be treated with absolutely the same human respect, decency, and civil equality as anyone else. But they don’t disprove traditional notions of gender as such — which have existed in all times, places, and cultures in human history and prehistory, and are rooted deeply in evolutionary biology and reproductive strategy.
  • Intersex people exist and, in my view, should not be genitally altered or “fixed” without their adult consent. But they do not somehow negate the overwhelming majority who have no such gender or sexual ambiguity.
  • the entire society does not need to be overhauled in order to make gay or trans experience central to it. Inclusion, yes. Revolution, no.
  • The added problem with this war on nature is the backlash it inevitably incurs. There’s a reason so many working-class men find it hard to vote for Democrats any more. And there’s a reason why a majority of white women last year voted for a man who boasted of sexual assault if the alternative was a triumph for contemporary left-feminism.
  • You can’t assault the core identity of most people’s lives and then expect them to vote for you. As a Trump supporter in Colorado just told a reporter from The New Yorker: “I’ve never been this emotionally invested in a political leader in my life. The more they hate him, the more I want him to succeed. Because what they hate about him is what they hate about me.”
  • One of the features you most associate with creeping authoritarianism is the criminalization of certain political positions. Is anything more anathema to a liberal democracy? If Trump were to suggest it, can you imagine the reaction?
  • And yet it’s apparently fine with a hefty plurality of the Senate and House. I’m referring to the remarkable bill introduced into the Congress earlier this year — with 237 sponsors and co-sponsors in the House and 43 in the Senate — which the ACLU and the Intercept have just brought to light. It’s a remarkably bipartisan effort, backed by Chuck Schumer and Ted Cruz, among many solid Trump-resisting Democrats and hard-line Republicans.
  • it would actually impose civil and criminal penalties on American citizens for backing or joining any international boycott of Israel because of its settlement activities. There are even penalties for simply inquiring about such a boycott. And they’re not messing around. The minimum civil penalty would be $250,000 and the maximum criminal penalty $1 million and 20 years in prison. Up to 20 years in prison for opposing the policies of a foreign government and doing something about it!
  • I’m not in favor of boycotting Israel when we don’t boycott, say, Saudi Arabia. But seriously: making it illegal?
  • Every now and again, you just have to sit back and admire the extraordinary skills of the Greater Israel lobby. You’ve never heard of this bill, and I hadn’t either. But that is partly the point. AIPAC doesn’t want the attention — writers who notice this attempted assault on a free society will be tarred as anti-Semites (go ahead, it wouldn’t be the first time) and politicians who resist it will see their careers suddenly stalled.
  • pointing out this special interest’s distortion of democracy is not the equivalent of bigotry. It’s simply a defense of our democratic way of life.

The Brain on Love - The New York Times - 0 views

  • A RELATIVELY new field, called interpersonal neurobiology, draws its vigor from one of the great discoveries of our era: that the brain is constantly rewiring itself based on daily life.
  • All relationships change the brain — but most important are the intimate bonds that foster or fail us, altering the delicate circuits that shape memories, emotions and that ultimate souvenir, the self
  • At birth, the brain starts blazing new neural pathways based on its odyssey in an alien world. An infant is steeped in bright, buzzing, bristling sensations, raw emotions and the curious feelings they unleash, weird objects, a flux of faces, shadowy images and dreams

  • As the most social apes, we inhabit a mirror-world in which every important relationship, whether with spouse, friend or child, shapes the brain, which in turn shapes our relationships.
  • Just consider how much learning happens when you choose a mate. Along with thrilling dependency comes glimpsing the world through another’s eyes; forsaking some habits and adopting others (good or bad); tasting new ideas, rituals, foods or landscapes; a slew of added friends and family; a tapestry of physical intimacy and affection; and many other catalysts, including a tornadic blast of attraction and attachment hormones — all of which revamp the brain.
  • During idylls of safety, when your brain knows you’re with someone you can trust, it needn’t waste precious resources coping with stressors or menace. Instead it may spend its lifeblood learning new things or fine-tuning the process of healing.
