Deborah Cohen is a senior natural scientist at the Rand Corp and the author of the book A Big Fat Crisis: The Hidden Forces Behind the Obesity Epidemic and How We Can End It. According to the book, there are lots of misunderstandings of obesity.

1).If you're obese, blame your genes.

    Obesity rates have increased. Yet, between 1980 and 2000, the number of Americans who are obese has doubled—too quickly for genetic factors to be responsible.

    At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.

2).If you're obese, you lack self-control.

    Research shows that if we are faced with too much information, we have a tendency to make poor dietary choices. Our world has become so rich in temptation that we can be led to consume too much in ways we can't understand. Even the most vigilant (警觉的) people may not be up to the task of controlling themselves.

3).Lack of access to fresh fruits and vegetables is responsible for obesity.

    Although the US Department of Agriculture estimates that fewer than 5 percent of Americans live in the “food deserts”, about 65 percent of the nation's population is overweight or obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.

4).The problem is not that we eat too much, but that we don't exercise.

    Michelle Obama's “Let's Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. But there was no significant decrease in physical activity levels as obesity rates climbed in the 1980s and 1990s. In fact, although a drop in work-related physical activity may account for up to 100 fewer calories burned, leisure physical activity appears to have increased. The problem is that we eat too much.

    Have you ever been to the world's smallest bookstore?

    The World's Smallest Bookstore, whose official name is just these three words, sits quietly about 100 miles northeast of Toronto.

    The bookstore is about 10 feet by 10 feet，so it is easy to imagine how tiny it really is. The bookstore is open 24 hours a day. Inside the bookstore are various books, especially literary books and classic authors' works. So if you are looking for something less popular, you may get a bit disappointed there.

Another special feature of this bookstore is that each book only costs three dollars. All the expenses are paid on the honor system, which means buyers should make a note of what they've bought and leave their money by themselves. So the tools of the trade in this bookstore are quite simple: pens, papers, light bulbs and a label-maker.

    In order to catch passers-by's attention, the billboards (广告牌) of the bookstore are several times bigger than the store itself. With these large eye-catchers, many people are willing to stop by and have a visit.

    My timing has always been a little off with Elizabeth Strout. I've read and pretty much admired everything she's written, but, for whatever reason, the books of hers I've picked to review have been the good ones, like Amy and Isabelle andThe Burgess Boys, rather than the extraordinary ones, like Olive Kitteridge, which won the 2009 Pulitzer Prize. Anything Is Possible is Strout's latest book and it's gorgeous. Like Olive Kitteridge, Anything Is Possible reads like a novel constructed out of linked stories. In fact, it's hard to know exactly what to call this — a novel or a short story collection. In any case, these stories are animated (栩栩如生) by Strout's signature themes: class humiliation, loneliness, spiritual and, sometimes, reawakening. When Strout is really on her game, as she is here, you feel like you've been carefully lowered into the unquiet depths of quiet lives.

    Strout began working on Anything Is Possible at the same time she was writing her novel My Name Is Lucy Barton, which was published last year. Lucy, a dirt-poor child who grows up to become a celebrated writer, floats in and out of these interlocking stories. Some characters catch a glimpse of her being interviewed on TV; one travels to see her at a bookstore. An older Lucy even appears “in the flesh” in one story when she returns home to the small town in rural Illinois where most of these tales are set to visit her troubled brother; but Anything Is Possible also stands on its own. Indeed, a few of the characters here would be ticked off if they thought their stories depended in any way on that Barton girl. Strout's writerly eye works like a 360 degree camera, so that a character or place that's on the margins of one tale takes center stage in a later one. This technique sounds contrived, but Strout carries it off lightly.

    ①One of the most powerful stories here is called “Dottie's Bed & Breakfast,” which is an establishment we readers glimpse earlier in the book. Dottie desires to be middle-class and she harbors a grudge (怨恨) against life because she's had to rent out rooms to make a living. Dottie also possesses a sensitive nose for sniffing out the lower-class origins of some of her guests.

    ②“Shoes always gave you away,” comments a woman in a story called “Cracked” about a houseguest's too-high cork wedges(坡跟鞋). And, in the final story here, called “Gift,” a once-poor man made good says, “The sense of apology did not go away, it was a tiring thing to carry.”

    ③But, back to Dottie. When an elderly doctor and his wife come to stay at her guesthouse, Dottie bonds over tea with the wife, Shelley, who shares a story about a long-ago social humiliation.

    ④At breakfast the next morning, however, Shelley obviously regrets that confidence and becomes the Doctor's wife again. She freezes Dottie out and puts her back in her place as the inn-keep.

    There's comic satisfaction in seeing Dottie secretly spitting into the breakfast jam, but the more profound rewards of this story have to do with its recognition of the many varieties of human insecurity — or, as Lucy Barton herself more bluntly puts it, the many ways “people are always looking to feel superior to someone else.”

    Other stories have to do with sexual shame, or with the tragic ways close neighbors or family members misread each other; but I'm making Anything Is Possible sound too grim when, in fact, so many of these stories end in an understated (低调的) gesture of forgiveness. Strout is in that special company of writers like Richard Ford, Stewart O'Nan and Richard Russo, who write simply about ordinary lives and, in so doing, make us readers see the beauty of both their worn and rough surfaces and what lies beneath.

New App Helps People Remember Faces

    Large gatherings such as weddings and conferences can be socially overwhelming. Pressure to learn people's names only adds to the stress. A new facial-recognition app could come to the rescue, but privacy experts recommend proceeding with caution.

    The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. "It breaks down these social barriers we all have when meeting somebody," says Barry Sandrew, who created the app and tested it at an event attended by about 1,000 people.

    After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee's face, the app identifies the individual, displays the person's name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app's creators say it automatically deletes users' data after an event.

    Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the app's creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app, they should know that "there may be unintended consequences down the road with that information being used in another context that might come back to bite you."

    The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or "face blindness," a condition that prevents people from recognizing individuals they have met. To use this app, a person first acquires an image of someone's face, from either the smartphone's camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data are stored only on a user's phone, according to the team behind the app.

    Over the centuries the French have lost a number of famous battles with the British. However, they've always felt superior in the kitchen. France has for centuries had a reputation for cooking excellence, and Britain for some of the worst cooking in the world. But according to a recent survey, that reputation may no longer reflect reality.

    In the survey, 71% of the Britons said they cook at home every day, while only 59% of the French said they cook daily. British home cooks spend more time cooking each week and also produce a greater variety of dishes than French home cooks.

    The reaction in London was predictably enthusiastic. British food has greatly improved since the 1990s. Once upon a time, the menu for many family meals would have been roast beef, potatoes and over-cooked vegetables, but not now. Home cooks are experimenting with the huge range of ingredients now available in British supermarkets and are preparing all kinds of new dishes, using the cookbooks that sell millions of copies every year. As a result, there's much more diversity in British food now, compared to French food, which tends to be very traditional.

    Some French people say that the survey did not show the whole picture. They agree that during the week French women don't cook as much as they used to because most of them work and don't have much time. They tend to buy ready-made or frozen dishes, but many of them make up for it on the weekend. There's also a difference between Paris and the countryside. It's true that people in Paris don't cook much, but elsewhere, cooking is still at the heart of daily life.

    For many French people, opinions about British food have not changed. When Bernard Blier, the food editor at a magazine, was asked about British food, he replied: "I don't go out of my way to try it. It is not very refined. You can say that I'm not a fan at all."

    Why is it that many people who have suffered a major shock, such as divorce or death of a family member, seem to be weaker against a variety of major and minor illness? One common idea among psychologists has been that people could deal with suffering more effectively if they were able to understand and accept it. Indeed, many experts stress the value of expressing thoughts and feelings connected with upsetting events.

    Recently, a team of medical researchers studied the links between describing psychologically painful events and long-term health. In one experiment healthy college students were asked to write about either personally disturbing experiences or ordinary topics over a period of four days. In the months afterwards, students who had chosen to show their inner thoughts and feelings in their writing visited the health center for illness much less often than those who had written about everyday topics.

    In an experiment that followed, another group of healthy students were given the four-day writing exercises. Some chose to write about highly personal and upsetting experiences (including loneliness, problems with family and friends, and health). When questioned immediately afterwards, they said that they did not feel any better. However, their blood samples(样本) taken before and after the experiment showed evidence of an improved resistance to illness. The white cells that fight off bacteria and viruses had increased their reaction and sensitivity to these "invaders". This trend continued over the following six weeks, when another blood sample was taken. Individuals who showed the best results were those who wrote about topics that they had actively kept from telling others about.

    The researchers suggested that failure to face up to painful experience can be a form of stress itself, and can increase the possibility of illness. It follows, then, that actively dealing with a major shock makes possible its understanding and acceptance. The answer is not to suffer in silence. It may not always be possible to talk about personal problems, but writing them down will help the body to fight disease in the long run.
