颠覆认知:着凉到底会不会导致感冒? | 商周专栏
从1914年德国 Kruse 教授首次发现感冒能传染到现在,一百多年的时间过去了。在过去的一个世纪里,科学界对着凉与感冒的关系已经基本清楚:普通感冒是由感冒病毒导致的急性上呼吸道感染,冷的环境能促进感冒的发生(通过增强病毒在体外的生存时长、增加病毒感染的机会、降低呼吸道细胞对病毒的免疫力等),但着凉和普通感冒无关。

Thicker than blood: A young Chinese woman's coming of age - SupChina
Always careful about what I ate, she enforced an even stricter diet. Certain types of animal products must be avoided because they contained growth hormones. Some seeds and plants could only be consumed in small quantities because they stimulated the sexual organs, per traditional Chinese medicine. In addition to her belief that the flow of the womb drained the brain, my mother dreaded the approach of womanhood for her daughter, a perilous world filled with lurking eyes and wandering hands.

The only item my mother cleaned with a vengeance was our underwear. She rinsed them by hand, and she boiled them in water. The designated utensil was a large porcelain washbasin with a pair of mandarin ducks printed on the bottom next to the character for “double happiness.” The basin was a wedding gift for her and my father, typical of their time.

“Only boiling water can kill all the germs,” my mother explained her peculiar method. “That place must be kept clean, otherwise you will get diseases, and people will think you are a prostitute.”

Is there any real distinction between ‘high’ and ‘low’ pleasures?
The difficulty with resolving this disagreement about the kinds of pleasure is not that we struggle to agree on the right answer. It’s that we’re asking the wrong question. The entire debate assumes a clear divide between the intellectual and bodily, the human and the animal, which is no longer tenable. These days, few of us are card-carrying dualists who believe that we are made of immaterial minds and material bodies. We have plenty of scientific evidence for the importance of biochemistry and hormones in all that we do and think

Eating illustrates how the difference between higher and lower pleasures is not what you enjoy but how you enjoy it.

Mill was therefore right to believe that pleasures come in higher and lower forms but wrong to think that we could distinguish them on the basis of what we take pleasure in. What matters is how we enjoy them, which means that higher and lower pleasures are not two discrete categories but form a continuum.

When we learn how to take pleasure in bodily things in ways that engage our hearts and minds as well as our five senses, we give up the illusion that we are souls trapped in mortal coils, and we learn how to be fully human. We are neither angels above bodily pleasures nor crude beasts slavishly following them, but psychosomatic wholes who bring heart, mind, body and soul to everything we do.

Notes on Being Very Tall
From there, every inch takes you further from attractive and deeper into a realm of the freakish, toward human spectacle.

If you asked me who I was then, I would say that I was a reader and a writer, the son of an immigrant, an avid traveler, still a bit too much of a talker. But my body always preceded my person, my mind. My height was an identity that I didn’t identify with, one that was imposed on me externally and that only over time did I learn to internalize.

The usher kept coming down the aisle and shining his flashlight into Palmer’s eyes.

Medicine’s Burning Question
“Inflammation is the final common pathway for pretty much all chronic diseases,” he told me. His recommended solution is an “anti-inflammatory diet”—omitting sugar, caffeine, beans, dairy, gluten, and processed foods, as well as taking a variety of supplements, including probiotics, fish oil, Vitamins C and D, and curcumin, a key molecule in turmeric.

Fermented food may be good for your gut, but does it taste good?

Anything that has undergone a form of chemical breakdown by bacteria, yeast or other microbes — from blue cheese to sourdough bread — is fermented.

To ferment, a food needs to be put in an airless environment (a sealed jar filled with liquid, for example) in which microbes are encouraged to feed off its natural sugars. The result is an acid that both kills off harmful bacteria and transforms the original food. Put cabbage in brine and the result is soft, tart sauerkraut. Ferment soy beans, as they do at Flat Three, and the result tastes a bit like a raisin.

Booth, who dedicated a chapter of his book, The Meaning of Rice, to the mould koji, calls the Japanese the kings of fermented foods. Miso soup is my go-to hangover cure, he says. I am totally convinced of the benefits of naturally fermented foods and I do think it is one of the reasons why the traditional Japanese diet is so good for you.

BBC - Future - How flying seriously messes with your mind
There are some studies, however, that show even relatively mild levels of hypoxia (deficiency in oxygen) can alter our ability to think clearly.

Human night vision can deteriorate by 5-10% at altitudes of just 5,000ft (1.5km). This is because the photoreceptor cells in the retina needed to see in the dark are extremely oxygen-hungry and can struggle to get all they need at a high altitude, causing them to work less effectively.

as the change in air pressure can also lead to passengers breaking wind more often.

Are We Ready for Intimacy with Robots?

Hiroshi Ishi­guro builds robots. Beautiful, realistic, uncannily convincing human replicas. His quest? Untangle the ineffable nature of human connection.

in Japan: the Advanced Telecommuni­cations Research Institute International in Nara and the Intelligent Robotics Laboratory on the campus of Osaka University.

Hiroshi Ishi­guro

the capacity to imbue such a machine with humanness—that ineffable presence the Japanese call sonzai-kan.

Ishi­guro believes that since we’re hardwired to interact with and place our faith in humans, the more humanlike we can make a robot appear, the more open we’ll be to sharing our lives with it.

He is convinced that human emotions, whether empathy or romantic love, are nothing more than responses to stimuli, subject to manipulation. Through the fluid interplay of its pneumatic joints, the arch of its mechanical brow, the tilt of its plastic skull, the many subtle movements achieved through years of research studying the human template, the android becomes more able to span that gap, to form a perfectly engineered bond with us. An elaborate metaphysical trick, perhaps—but what does that matter, if it fills a need? If it feels real?

Designed with the physical proportions that its human owner prefers, the preferred voice timbre and eye color and personality type, and the ability to recall and riff on its owner’s personal stories and little jokes, android will captivate human.

someone would be left alone in their advanced age to relive the joy of having a child through the cradling of a robot with stunted limbs.

The countless ways in which we judge someone based on their appearance all evaporate in the face of this neutral appearance, as Hiroshi calls the Telenoid’s blank, abstract body. And what is left in its place is that ineffable thing he has been trying to define: a distinctly human presence, free of the uncanny. It is an outsider, like its maker—but one who manages to trigger our affection. While holding the android, it hardly matters that this humanness is emitting from something that barely resembles a human at all.

Is Fat Killing You, or Is Sugar?

Women in the nineteenth century stuffed themselves into near-suffocating corsets to achieve an hourglass figure with an unnaturally tiny waist. Weight-loss regimens included consuming soap, chalk, pickles, digitalis, camphor tea, grapefruit (which was thought to contain fat-dissolving enzymes), potassium acetate (a diuretic), and ipecac (which induces vomiting). People tried sweating their fat away in rubber suits, or squeezing it away in a pressurized reducing machine.

The importance of calories—if energy gained exceeds output, the excess becomes fat—remains one of the few unchallengeable facts in the field of dietary science. Still, further research has shown that calories eaten are only part of what determines weight. Our metabolism reflects an interplay of things like genes, hormones, and the bacteria that populate the gut, so how much energy we absorb from what we eat varies from person to person.

The immediate postwar years also brought the first sustained scientific assault on dietary fat. Ancel Keys, a physiologist at the University of Minnesota, who had spent the war developing nutritionally optimal Army rations and studying the effects of starvation, became interested in the high rates of heart attack among a seemingly well-fed sector of the population—American businessmen. He soon became convinced that the saturated fats found in meat and dairy products were the cause, and thus began the war on fat that galvanized my parents. Keys became, with his wife, Margaret, an advocate for the Mediterranean diet of unsaturated fats. Their books promoting the diet were best-sellers, and Keys, who spent his latter years in Italy, lived to the age of a hundred. (Margaret lived to ninety-seven.)

Taubes believes that a wide range of seemingly unrelated diseases—diabetes, heart disease, cancer, stroke, and Alzheimer’s, which account for five of the top ten causes of death in the U.S.—are in fact linked, and that dietary sugar is the cause of them all, as well as of other disorders that associate with these illnesses, among them polycystic ovary syndrome (PCOS), rheumatoid arthritis, gout, varicose veins, asthma, and inflammatory bowel disease.

there is no conclusive evidence that excess dietary sugar per se causes diabetes.

To imagine that, just because cancer cells like glucose, elevated levels of it might prompt healthy cells to become cancerous is to take a vast, unsubstantiated leap.

What this means for most of us is that common sense should prevail. Eat and exercise in moderation; maintain a diet consisting of balanced amounts of protein, fat, and carbohydrates; make sure you get plenty of fruit and vegetables. And enjoy an occasional slice of chocolate cake.

Yuval Noah Harari challenges the future according to Facebook
If Facebook really attempts to formulate a set of universal values, it will enjoy one big advantage over many previous institutions that attempted to do so. Unlike the early Christian church, or Lenin’s Communist party, Facebook is a truly global network with close to 2bn users. Yet Facebook also suffers from one big disadvantage. Unlike the Christian church and the Communist party, it is an online network.

Physical communities have a depth that virtual communities cannot hope to match, at least not in the near future.

People estranged from their bodies, senses and physical environment are likely to feel alienated and disoriented.

People feel bound by elections only when they share a basic bond with most other voters. The ancient tribes along the Yellow River lacked a common set of values, and consequently they were unable to unite through a peaceful democratic process. It took a lot of violence to hammer them together into a single empire.

If something exciting happens, the gut instinct of Facebook true-believers is to draw their smartphones, take a picture, post it online, and wait for the “likes”. In the process they hardly pay attention to what they actually feel. Indeed, what they feel is increasingly determined by the online reactions rather than by the actual experience.

(A blueprint of such an alternative model has actually been suggested recently by Tristan Harris, an ex-Googler and tech-philosopher who came up with a new metric of “time well spent”.)

How to Sleep

While no one knows why we sleep, it is a universal biological imperative; no animal with a brain can survive without it. Dolphins are said to sleep with only half their brain at a time, keeping partially alert for predators. Many of us spend much of our lives in a similar state.

If coffee does have an effect on longevity, it is likely a result of something more global than the potential effect of antioxidants—such as the fact that constant exposure to caffeine, even at low levels, suppresses appetite (in a world where most people eat more than is ideal). Or that it encourages social interaction—it inclines us to go out and do things with people—which itself is generally beneficial to health. These are legitimately positive results. But as with all chemicals, the comprehensive effect of caffeine on our health depends on how, and how much, we use it.

When light enters your eye, it hits your retina, which relays signals directly to the core of your brain, the hypothalamus. The size of an almond, the hypothalamus has more importance per volume than any other part of your body. Yes, that includes the sex organs—you would have no sex drive without the hypothalamus. This almond is the interface between the electricity of the nervous system and the hormones of the endocrine system. It takes sensory information and directs the body’s responses, so that the body can stay alive.

Men also engaged in more touching after the handshake or post-boxing embrace. In tennis 42.5% of the matches between men concluded with the winner touching the loser’s arm or body in addition to the handshake, while only 12.5% of women’s matches ended this way. Ping pong showed similar results, with 33% of the male matches involving additional physical contact between the competitors while female matches showed none. (The high net in badminton and the many individuals interacting with fighters after boxing bouts made it impossible to monitor post-handshake contact in those sports.)

Lunch with the FT: Rob Rhinehart —
“Humans have this novelty bias where they think that new information is somehow more relevant, but most of the information generated in a day is noise and what’s really important is the patterns that have held true through generations. I feel like I could be reading a philosophy book that has held true for centuries or I could get stressed out by what’s on the news today.”

really creative work comes from states of flow and concentration, and it’s really hard to get into that and it’s really easy to become distracted from that. I think having that flexible day allows people to increase the chance of entering that creative flow, and that’s good for them and it’s good for the business.”

Why Jet Lag Can Feel Worse When You Travel West to East -

This is all because the body’s internal clock has a natural period of slightly longer than 24 hours, which means that it has an easier time traveling west and lengthening the day than traveling east and shortening the day, Dr. Girvan said.

It all comes back to whether you’re a lark — an early riser — or an owl, and most people are a little owlish, said David Welsh, a neuroscientist at the University of California, San Diego, who studies the body’s pacemaker cells and was not involved in the study.

Posture Affects Standing, and Not Just the Physical Kind
I bought my current vehicle, a Toyota Sienna minivan, largely because I was immediately comfortable when I got behind the wheel for a test drive. My entire back was supported, so not a twinge was felt there, unlike what happens in many other cars. I could also easily see over the steering wheel without tilting my head back, which is not the case in most other vehicles. And I could reach the floor pedals without unduly extending my leg and straining my lower back.

Poor posture can have ill effects that radiate throughout the body, causing back and neck pain, muscle fatigue, breathing limitations, arthritic joints, digestive problems and mood disturbances. It can also create a bad impression when applying for a job, starting a relationship or making new friends.

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

Why is my hangover so bad? | Life and style | The Guardian
Hangovers occur due to the side-effects of the chemical produced when alcohol is broken down. Alcohol itself is fairly harmless – but enzymes convert it to acetaldehyde, which does the damage. The longer the acetaldehyde hangs around, the worse you and your liver feel. Other enzymes help to clear the acetaldehyde away, but the rates at which both happen are extremely variable in different people.

How Mindfulness Can Jumpstart Our Exercise Routines -
Of course, being aware and in the moment during exercise also means experiencing, fully, your twinging muscles, declining pace, hunger, and unbecoming spite when a grandmother passes you on the trail. But even these aspects of exercise should be more tolerable with mindfulness, Ms. Tsafou said. As she and her colleagues wrote in the study, mindfulness “facilitates the acceptance of things as they occur,” enabling us to “accept negative experiences and view them as less threatening.

The Physical Exam as Refuge -

Countless times, I have found that it is only during the physical exam that patients reveal what is truly on their mind. Whether it is the cough that they are reminded of now that I am listening to their lungs, or whether it is the domestic violence, the eating disorder or the genital symptoms that they feel comfortable revealing once we are in a more intimate setting — there is something about touch that changes the dynamic.

But then the doctor and patient move to the exam table, and everything changes. This is often the first moment that they can talk directly, without the impediment of technology. They are physically closer to each other, actually touching. This is an intimacy, albeit of the nonromantic type, but an intimacy nonetheless. And all intimacies have an effect of changing the dynamics of the interaction. Obviously, there is a risk of changing for the worse, but in my experience it is almost always a change for the better. Once a doctor and patient are at the exam table, touching, talking without the computer between them, conversation of a different sort is possible.
