Food serves as a form of communication in two basic ways. Sharing bread or other foods is a common human tradition that can promote unity and trust. Food can also have a special meaning, and play an important role in a family or culture's celebrations or traditions. The foods we eat—and when and how we eat them—are often unique to a particular culture or may even differ between rural(郊区的) and urban(市区的) areas within one country.

    Sharing bread, whether during a special occasion(时刻) or at the family dinner table, is a common symbol of togetherness. Many cultures also celebrate birthdays and marriages with cakes that are cut and shared among the guests. Early forms of cake were simply a kind of bread, so this tradition has its roots in the custom of sharing bread.

    Food also plays an important role in many New Year celebrations. In the southern United States, pieces of corn bread stand for blocks of gold for prosperity(兴旺) in the New Year. In Greece, people share a special cake called vasilopita. A coin is put into the cake, which signifies(预示) success in the New Year for the person who receives it.

    Many cultures have ceremonies to celebrate the birth of a child, and food can play a significant role. In China, when a baby is one month old, families name and welcome their child in a celebration that includes giving red-colored eggs to guests. In many cultures, round foods such as grapes, bread, and moon cakes are eaten at welcome celebrations to represent family unity.

    Nutrition(营养) is necessary for life, so it is not surprising that food is such an important part of different cultures around the world.

    Love to sink into your chairs and relax when you get to school. Then you will not be happy to hear that schools all over the world are seriously considering exchanging traditional desks for ones with no seats at all — Yes, that means you will be encouraged to stand through those already too long math and science lessons! Why would anyone even think of putting kids to such cruelty. Experts say it improves their health and helps fight obesity. While that may seem a little far-fetched (牵强的), the officials at the few schools around the world seem to agree.

    Among them are educators from the College Station Independent School District in Texas, who recently completed a week-long experiment involving 480 students across three elementary schools. The 374 kids that agreed to participate in the study were provided a device that helped record step count and calorie consumption over the entire period.

    All 25 teachers involved in the study reported that students appeared to be more alert and concentrate better, when allowed to stand. The one thing that did surprise the researchers was that younger kids were more willing to stay standing than kids in higher grades. They believe this may have something to do with the fact that after years of being asked to “sit still”, older kids have a harder time adjusting to this unexpected freedom.

    American schools are not the only ones reporting success with stand-up desks. Four schools in Perth, Australia, which have been testing them since October 2013, have seen similar results. In May 2014, Grove House Primary School in West Yorkshire, became Europe's first test one, with a seven-week trial that involved the use of desks made by Ergotron in their fifth-grade classrooms. While official results are not out yet, early reactions from both teachers and students, have been extremely encouraging.

    The findings of these studies and others done previously, all seem to mean that allowing kids to move around in classrooms is a win-win for students and teachers — it helps kids get healthier and provides educators with a more attentive audience.

    My grandfather died more than twenty-five years ago. I was fifteen then. He was kind, strong, fair, and very funny. When I was a young musician, he was my biggest fan. I played my violin for him when he visited, and he loved everything, but each time he had one request. “Could you play Amazing Grace%” he asked, full of hope and with a twinkle in his eye, because he knew my answer was always, “I don't know that one!” We went through this routine at every major holiday, and I always figured I'd have time to learn it for him later.

    About the time I entered high school and started guitar, Grandpa got cancer. The last time I saw him alive was Thanksgiving weekend in 1985. My mom warned us that Grandpa didn't look the same anymore and that we should prepare ourselves. For a moment I didn't recognize him. He looked so small among all the white sheets. We had all gathered in Ohio for the holiday, and I'm sure we all knew we were there to say good-bye. I can see now that Grandpa held on long enough to see us each one more time. I remember how we ate in the dining room and laughed and talked while Grandpa rested in his hospital bed. I wonder if it was sad for him to be alone with our voices and laughter. Knowing Grandpa, he was probably content.

    The next morning, I found my moment alone with him. I pulled out my guitar, tuned to his appreciative gaze, and finally played for him Amazing Grace. I had worked on it for weeks, knowing it never mattered whether I actually played it well and choosing not to believe as I played that it was my last concert for my biggest fan. The cancer had stolen his smile, but I saw joy in his eyes. He held my hand afterward, and I knew I had done something important.

    I argued with people all through college about my music major. I was told by strangers that music wouldn't make me any money and it wasn't useful like being a doctor. But I know first-hand that with music I was able to give my grandpa something at a point when no one else could.

    "The history of the world is but the biography (传记) of great men," argued Thomas Carlyle, the advocate of what has come to be known as the "Great Man Theory of History." This theory suggests that the broader movements and outline of history all go back to the leadership of great individuals who had unique influence on their times. Whether or not Carlyle's theory proves true is debatable, but that certain individuals cast long shadows is not.

    As one who is entrusted with a leadership position, I find it profitable to read of others who have led. Wherever you find me, you'll likely find a good biography nearby. Why is this the case? First, I find good biographies fascinating. I'll occasionally read a novel, but I've never been overly drawn to fiction. I have found myself unable to sleep while in the struggle of the Battle of Britain in William Manchester's The Last Lion. For me, not to read biographies would rob me of pleasure in my life.

    Second, I find good biographies informative. A good biographer tells not only the story of a person, but also of their times. Reading a good biography is like wandering through an intellectual shopping mall. The first store is what drew you there, but you will be pleasantly surprised along the way at what other items grab your attention. You'll find no better account of the British Empire at its peak than the opening chapters of Manchester's Visions of Glory, volume one of his The Last Lion. Strictly speaking, a biography is but a slice of history.

    Third, I find good biographies relaxing. Winston Churchill once noted a man who works with his hands should have a hobby that engages his mind, and a man who works with his mind should have a hobby that engages his hands. Another way to apply Churchill's saying is to combine technical, pen-in-hand vocational reading with leisurely biographical reading. Indeed, few things are more relaxing to me than winding down the evening and entering into another world.

    This is why I love reading good biographies, and why I pity the person who neglects them. Don't be counted among their number.

What a Messy Desk Says About You

    For some time, psychologists have been studying how personality traits affect health and health-related choices. Not surprisingly, they have found that people blessed with innate conscientiousness, meaning that they are organized and predictable, typically eat better and live longer than people who are disorderly. They also tend to have immaculate offices.

    What has been less clear is whether neat environments can produce good habits even in those who aren't necessarily innately conscientious. To find out, researchers at the University of Minnesota conducted a series of experiments. In the first experiment, they randomly assigned a group of college-age students to spend time in two office spaces, one of which was very neat, the other wildly cluttered (乱堆) with papers and other work-related stuff. The students spent their time filling out questionnaires unrelated to the study. After 10 minutes, they were told they could leave with an apple or a chocolate bar. Those students who sat in the orderly office were twice as likely to choose the apple as those who sat among the mess.

    A second experiment, however, found that working in chaos has its advantages, too. In this one, college students were placed in a messy or a neat office and asked to dream up new uses for Ping-Pong balls. Those in messy spaces generated ideas that were significantly more creative, according to two independent judges, than those in offices where stacks of papers and other objects were neatly arranged.

    The results were something of a surprise, says Dr. Vohs, the leader of the study. Few previous studies found much virtue in disorder. The broken window theory, proposed decades ago, holds that even slight disorder and neglect can encourage indifference and poor discipline.

    But in the study by Dr. Vohs, disordered offices encouraged originality and a search for novelty. In the final portion of the study, adults were given the choice of adding a health "boost" to their lunchtime smoothie that was labeled either "new" or "classic." The volunteers in the messy space were far more likely to choose the new one; those in the tidy office generally chose the classic version. "Disorderly environments seem to inspire breaking free of tradition," Dr. Vohs and her co-authors conclude in the study, "which can produce fresh insights."

    The implications of these findings are also practical. "My advice would be, if you need to think outside the box for a future project", Dr. Vohs says, "then let the clutter rise and free your imagination. But if your primary goal is to eat well or to go to the gym, pick up around your office first. By doing this, the naturally messy can acquire some of the discipline of the conscientious."

Europe is famous for big cities and world-class art museums. It's easy not to notice the small, beautiful villages in Europe. However, if you're after relaxation, peaceful country walks, beautiful buildings, and chances for different cultures on your next trip, consider cutting down some of your city time and head out to a village instead. Here are three of the most beautiful villages in Europe, along with our top picks for places to stay in each.

Bibury in Gloucestershire, England

Often praised as the most beautiful village of the Cotsworlds, Bibury is also one of the most popular places for visitors to stay in the area, and attracts a lot of tourists from around the world. It's set among the green hills that the area is known for and is composed of light-beige(浅米色) stone houses, including the famous Arlington Row, a line of houses dating back to 1380.

Cong in County Mayo, Ireland

Set on a small sea-facing island on the western coast of Ireland, Cong is a quiet village that's famous for its grey stone ruins and many outdoor activities. One of the biggest reasons for its fame is that the 1952 film The Quiet Man was made there, but the biggest draw for most visitors is the chance to visit (or stay in) Ashford Castle, which is now run as a great expensive hotel.

Montepulciano in Tuscany, Italy

Spread over a hilltop nearly 2, 000 meters above sea level, the Tuscan village of Montepulciano offers beautiful buildings from the Middle Ages, as well as many chances to visit wineries(酿酒厂) and taste the locally produced Vino Nobel di Montepulciano. With fortifications(防御工事) dating back to the 14th century, the village has churches and public squares, which are truly fascinating.
