How Navy SEALs Conquer Fear and Anxiety - SEALFIT - 1 views

  • Stress just means resistance or pressure. We need stress to grow as humans; it can be a positive force if mentally framed correctly — even enhancing performance to blast through a deadline. But prolonged stress erodes your performance and wellbeing.
  • The workload we endured seemed impossible. But, amazingly, it was. Our “Why” enabled us to tap into our 20X Factor and an uncommon resolve.
  • Despite the chaos, a SEAL is trained to focus with single-mindedness on the immediate threat and dispatch one target at a time. Excessive thinking would have killed me. My unconscious competence combined with relentless training saved my life.

  • I was useless as a navigator but couldn’t abort the mission. My teammate took over. After my frustration and fear had dissipated, I slowed my breathing and held my breath at the inhale and exhale. I focused my mind on the breathing cycle while repeating the positive mantra, “Feeling good, looking good, ought to be in Hollywood!” thus accelerating my concentration and positivity. Suddenly we came to a halt. We’d arrived at the destination. A miserable three hours felt like an enjoyable 45 minutes just through focused breathing.
  • he had his SEAL Team visualize the mission hundreds of times. They mentally pictured everything that could go wrong, as well as what the victory would look like. They also rehearsed it live in a mock-up of the compound the terrorist was holed up in. This tactic is a key to SEAL success.
  • SEAL’s don’t take anything for granted and ensure that they win in their minds before stepping onto the helo
  • The SEAL ethos makes quitting not an option. SEALs persevere to “find a way or make one.” Things inevitably go wrong, but they don’t entertain the concept of failure

Why pilots are seeing UFOs | CNN - 0 views

  • For centuries, people have witnessed unexplained lights in the sky and thought that perhaps they might be ghosts or angels. However, it was in the summer of 1947 when a different explanation became popular. Following a widely reported incident over Mt. Rainier in Washington state, people began to believe that these unidentified flying objects (UFOs) are actually alien spacecraft prowling the Earth.
  • Over the past 70 years, more than ten thousand similar reports have been made.
  • Some accounts simply arose from nothing more than the fevered imaginations of UFO enthusiasts.
  • ...5 more annotations...
  • In 2004, Navy fighter jet pilots operating from the USS Nimitz aircraft carrier reported seeing UFOs off the coast of San Diego. And, more recently, other military pilots flying with the USS Theodore Roosevelt in the Atlantic made similar claims. The news of those accounts became public knowledge from a story in the New York Times and a new miniseries on the History Channel.
  • The problem is that many people jump directly from the “unidentified” in “UFO” to “flying saucer.” And that’s just too large a jump to be reasonable. There is simply no credible evidence that the Earth is being visited by aliens. There are no artifacts, no clear photographs, no captured aliens, no alien bodies – nothing.
  • An eyewitness can be an unreliable source of information and, in the case of something as extraordinary as the observation of alien spacecraft, pedestrian evidence simply won’t do. As Carl Sagan often said, extraordinary claims require extraordinary evidence.
  • Even though there were multiple observations of multiple phenomena, what is missing is multiple reports of the same phenomenon. It would be hasty to link these independent observations together.
  • But I’m going to need much better evidence than what we have so far. In the meantime, let’s keep an eye on these reports. You know… just in case.

The Difference Between a Language and a Dialect - The Atlantic - 0 views

  • a language is a dialect with an army and a navy.”
  • The very fact that “language” and “dialect” persist as separate concepts implies that linguists can make tidy distinctions for speech varieties worldwide. But in fact, there is no objective difference between the two: Any attempt you make to impose that kind of order on reality falls apart in the face of real evidence.
  • The idea of distinguishing “languages” from “dialects” is of no logical use here. As often as not, it’s more that speech is a little different from place to place, such that a person can get along speaking when in the town a few valleys over; one starts having trouble the further away he gets; and after a traveling a certain distance can no longer understand a thing anyone is saying.
  • ...8 more annotations...
  • Worldwide, some mutually understandable ways of speaking, which one might think of as “dialects” of one language, are actually treated as separate languages
  • It turns out that it’s also impossible to determine precisely where one “language” leaves off and another begins
  • As such, English tempts one with a tidy dialect-language distinction based on “intelligibility”: If you can understand it without training, it’s a dialect of your own language; if you can’t, it’s a different language
  • The only thing that can save an attempt to impose a formal definition on the terms “language” and “dialect” now is perhaps to be found in popular usage, which suggests that languages are written and standardized and have a literature, while dialects are oral, without codified rules, and have no literature.
  • Namely, it’s the implication that there is something lesser about a “dialect.
  • As often as not, obscure, unwritten “dialects” are much more grammatically complicated than familiar “languages.”
  • A language, then, is indeed a dialect with an army and a navy; or, more to the point, a language is a dialect that got put up in the shop window.
  • In popular usage, a language is written in addition to being spoken, while a dialect is just spoken. But in the scientific sense, the world is buzzing with a cacophony of qualitatively equal “dialects,” often shading into one another like colors (and often mixing, too), all demonstrating how magnificently complicated human speech can be.

What Have We Learned, If Anything? by Tony Judt | The New York Review of Books - 0 views

  • During the Nineties, and again in the wake of September 11, 2001, I was struck more than once by a perverse contemporary insistence on not understanding the context of our present dilemmas, at home and abroad; on not listening with greater care to some of the wiser heads of earlier decades; on seeking actively to forget rather than remember, to deny continuity and proclaim novelty on every possible occasion. We have become stridently insistent that the past has little of interest to teach us. Ours, we assert, is a new world; its risks and opportunities are without precedent.
  • the twentieth century that we have chosen to commemorate is curiously out of focus. The overwhelming majority of places of official twentieth-century memory are either avowedly nostalgo-triumphalist—praising famous men and celebrating famous victories—or else, and increasingly, they are opportunities for the recollection of selective suffering.
  • The problem with this lapidary representation of the last century as a uniquely horrible time from which we have now, thankfully, emerged is not the description—it was in many ways a truly awful era, an age of brutality and mass suffering perhaps unequaled in the historical record. The problem is the message: that all of that is now behind us, that its meaning is clear, and that we may now advance—unencumbered by past errors—into a different and better era.

  • Today, the “common” interpretation of the recent past is thus composed of the manifold fragments of separate pasts, each of them (Jewish, Polish, Serb, Armenian, German, Asian-American, Palestinian, Irish, homosexual…) marked by its own distinctive and assertive victimhood.
  • The resulting mosaic does not bind us to a shared past, it separates us from it. Whatever the shortcomings of the national narratives once taught in school, however selective their focus and instrumental their message, they had at least the advantage of providing a nation with past references for present experience. Traditional history, as taught to generations of schoolchildren and college students, gave the present a meaning by reference to the past: today’s names, places, inscriptions, ideas, and allusions could be slotted into a memorized narrative of yesterday. In our time, however, this process has gone into reverse. The past now acquires meaning only by reference to our many and often contrasting present concerns.
  • the United States thus has no modern memory of combat or loss remotely comparable to that of the armed forces of other countries. But it is civilian casualties that leave the most enduring mark on national memory and here the contrast is piquant indeed
  • Today, the opposite applies. Most people in the world outside of sub-Saharan Africa have access to a near infinity of data. But in the absence of any common culture beyond a small elite, and not always even there, the fragmented information and ideas that people select or encounter are determined by a multiplicity of tastes, affinities, and interests. As the years pass, each one of us has less in common with the fast-multiplying worlds of our contemporaries, not to speak of the world of our forebears.
  • What is significant about the present age of transformations is the unique insouciance with which we have abandoned not merely the practices of the past but their very memory. A world just recently lost is already half forgotten.
  • In the US, at least, we have forgotten the meaning of war. There is a reason for this. I
  • Until the last decades of the twentieth century most people in the world had limited access to information; but—thanks to national education, state-controlled radio and television, and a common print culture—within any one state or nation or community people were all likely to know many of the same things.
  • it was precisely that claim, that “it’s torture, and therefore it’s no good,” which until very recently distinguished democracies from dictatorships. We pride ourselves on having defeated the “evil empire” of the Soviets. Indeed so. But perhaps we should read again the memoirs of those who suffered at the hands of that empire—the memoirs of Eugen Loebl, Artur London, Jo Langer, Lena Constante, and countless others—and then compare the degrading abuses they suffered with the treatments approved and authorized by President Bush and the US Congress. Are they so very different?
  • As a consequence, the United States today is the only advanced democracy where public figures glorify and exalt the military, a sentiment familiar in Europe before 1945 but quite unknown today
  • the complacent neoconservative claim that war and conflict are things Americans understand—in contrast to naive Europeans with their pacifistic fantasies—seems to me exactly wrong: it is Europeans (along with Asians and Africans) who understand war all too well. Most Americans have been fortunate enough to live in blissful ignorance of its true significance.
  • That same contrast may account for the distinctive quality of much American writing on the cold war and its outcome. In European accounts of the fall of communism, from both sides of the former Iron Curtain, the dominant sentiment is one of relief at the closing of a long, unhappy chapter. Here in the US, however, the story is typically recorded in a triumphalist key.5
  • For many American commentators and policymakers the message of the twentieth century is that war works. Hence the widespread enthusiasm for our war on Iraq in 2003 (despite strong opposition to it in most other countries). For Washington, war remains an option—on that occasion the first option. For the rest of the developed world it has become a last resort.6
  • Ignorance of twentieth-century history does not just contribute to a regrettable enthusiasm for armed conflict. It also leads to a misidentification of the enemy.
  • This abstracting of foes and threats from their context—this ease with which we have talked ourselves into believing that we are at war with “Islamofascists,” “extremists” from a strange culture, who dwell in some distant “Islamistan,” who hate us for who we are and seek to destroy “our way of life”—is a sure sign that we have forgotten the lesson of the twentieth century: the ease with which war and fear and dogma can bring us to demonize others, deny them a common humanity or the protection of our laws, and do unspeakable things to them.
  • How else are we to explain our present indulgence for the practice of torture? For indulge it we assuredly do.
  • “But what would I have achieved by proclaiming my opposition to torture?” he replied. “I have never met anyone who is in favor of torture.”8 Well, times have changed. In the US today there are many respectable, thinking people who favor torture—under the appropriate circumstances and when applied to those who merit it.
  • American civilian losses (excluding the merchant navy) in both world wars amounted to less than 2,000 dead.
  • We are slipping down a slope. The sophistic distinctions we draw today in our war on terror—between the rule of law and “exceptional” circumstances, between citizens (who have rights and legal protections) and noncitizens to whom anything can be done, between normal people and “terrorists,” between “us” and “them”—are not new. The twentieth century saw them all invoked. They are the selfsame distinctions that licensed the worst horrors of the recent past: internment camps, deportation, torture, and murder—those very crimes that prompt us to murmur “never again.” So what exactly is it that we think we have learned from the past? Of what possible use is our self-righteous cult of memory and memorials if the United States can build its very own internment camp and torture people there?
  • We need to learn again—or perhaps for the first time—how war brutalizes and degrades winners and losers alike and what happens to us when, having heedlessly waged war for no good reason, we are encouraged to inflate and demonize our enemies in order to justify that war’s indefinite continuance.

How to be good at stress | ideas.ted.com - 0 views

  • He dedicated his career to identifying what distinguishes people who thrive under stress from those who are defeated by it. The ones who thrive, he concluded, are those who view stress as inevitable, and rather than try to avoid it, they look for ways to engage with it, adapt to it, and learn from it.
  • what is new is how psychology and neuroscience have begun to examine this truism. Research is beginning to reveal not only why stress helps us learn and grow, but also what makes some people more likely to experience these benefits.
  • . But the stress response doesn’t end when your heart stops pounding. Other stress hormones are released to help you recover from the challenge. These stress-recovery hormones include DHEA and nerve growth factor, both of which increase neuroplasticity. In other words, they help your brain learn from experience
  • ...7 more annotations...
  • . DHEA is classified as a neurosteroid; in the same way that steroids help your body grow stronger from physical exercise, DHEA helps your brain grow stronger from psychological challenges. For several hours after you have a strong stress response, the brain is rewiring itself to remember and learn from the experience. Stress leaves an imprint on your brain that prepares you to handle similar stress the next time you encounter it.
  • Psychologists call the process of learning and growing from a difficult experience stress inoculation. Going through the experience gives your brain and body a kind of stress vaccine. This is why putting people through practice stress is a key training technique for NASA astronauts, Navy SEALS, emergency responders and elite athletes, and others who have to thrive under high levels of stress.
  • . (This is part of what makes the science of stress so fascinating, and also so puzzling.
  • Higher levels of cortisol have been associated with worse outcomes, such as impaired immune function and depression. In contrast, higher levels of DHEA—the neurosteroid—have been linked to reduced risk of anxiety, depression, heart disease, neurodegeneration and other diseases we typically think of as stress-related.
  • An important question, then, is: How do you influence your own — or somebody else’s — growth index?
  • This mindset can actually shift your stress physiology toward a state that makes such a positive outcome more likely, for example by increasing your growth index and reducing harmful side effects of stress such as inflammation.
  • Other studies confirm that viewing a stressful situation as an opportunity to improve your skills, knowledge or strengths makes it more likely that you will experience stress inoculation or stress-related growth. Once you appreciate that going through stress makes you better at it, it gets easier to face each new challenge. And the expectation of growth sends a signal to your brain and body: get ready to learn something, because you can handle this.
  •  
    Good timing for an article about stress considering we are taking exams this week.  New physiology studies suggest that your brain releases a growth hormone  after a stressful experience (that is like steroid for the brain) that temporarily increases your ability to learn.   Interesting to think just how this trait/hormone was evolved...

The Navy's USS Gabrielle Giffords and the Future of Work - The Atlantic - 0 views

  • Minimal manning—and with it, the replacement of specialized workers with problem-solving generalists—isn’t a particularly nautical concept. Indeed, it will sound familiar to anyone in an organization who’s been asked to “do more with less”—which, these days, seems to be just about everyone.

  • But once cadets got into actual command environments, which tend to be fluid and full of surprises, a different picture emerged. “Psychological hardiness”—a construct that includes, among other things, a willingness to explore “multiple possible response alternatives,” a tendency to “see all experience as interesting and meaningful,” and a strong sense of self-confidence—was a better predictor of leadership ability in officers after three years in the field.
  • Because there really is no such thing as multitasking—just a rapid switching of attention—I began to feel overstrained, put upon, and finally irked by the impossible set of concurrent demands.

This is distinct from “crystallized intelligence”—the accumulated facts and know-how on your hard drive—which peaks in your 50
  • Others noticed the change but continued to devote equal attention to all four tasks. Their scores fell. This group, Hambrick found, was high in “conscientiousness”—a trait that’s normally an overwhelming predictor of positive job performance. We like conscientious people because they can be trusted to show up early, double-check the math, fill the gap in the presentation, and return your car gassed up even though the tank was nowhere near empty to begin with. What struck Hambrick as counterintuitive and interesting was that conscientiousness here seemed to correlate with poor performance.

  • DaSilva said that potential Brexit complications were on the radar of travelers' concerns last year, but, with a no-deal averted and the pandemic taking center stage, it's no longer an issue for her guests. In fact, three of the top five most searched trips on their website involve Great Britain.
