For the Travel section, writers and editors selected special items to profile from a dozen cities.

Brussels:Chocolate

    Nearly half the chocolate consumed in the world is eaten in Europe, and Belgium—with average consumption of 14.99 pounds per person a year—certainly covers its fair share. While Brussels, the country's capital, is home to hundreds of chocolate makers, what makes a visit necessary is the rich heritage of traditional chocolate makers.

Budapest: Paprika (红辣椒)

    The job of preparing Hungarian paprika was once considered too dangerous for mothers to do. A woman who touched her children upon returning from work risked burning them, so only the elderly and unmarried were allowed the delicate task of separating the skin from the flesh. But by the early 20^th century, sweeter varieties and a machine turned paprika into a common feature of all Hungarian cuisine.

Lisbon: Tiles (瓷砖)

    Is there a bluer Country than Portugal? The blue sky and Atlantic Ocean embrace the land. The blue moods of Fado, the dark folk music, form the national soundtrack. And all across Portugal, the typically blue designs of azulejos—ceramic tiles—are spread across churches, castles, palaces, university halls, parks... The result is a beautiful land of Christian saints, Portuguese kings, historical glories, aristocrats at leisure, seascapes and so on.

Madrid: Guitars

    Walking into one of Madrid's storied guitar makers' workshops can feel like stepping into the past. Curly wood shavings, from the palest pine to ebony, fall onto the floor as artisans turn some humble wood into works of art. It's painstaking work—all done by hand—with classical guitar models and the methods of making them changing little over the last century.

    According to a recent study out of the University of Pennsylvania's Wharton School, men with shaved heads are considered to be more manly, powerful, and successful than those with longer hair or thinning(稀少的) hair. Besides, in some cases, they are considered to have greater leadership potential (潜力). That may explain why the power-buzz look has become popular among business leaders in recent years.

    Albert Mannes, Wharton management lecturer, said he was encouraged to do the research after noticing that he was treated with more respect when he shaved off his thinning hair.

    Mannes did three experiments to test people's impression of men with shaved heads. In one of the experiments, he showed 344 subject photos of the same men in two versions: one showing the men with hair and the other showing them with their hair digitally removed, so their heads appear shaved. In all three tests, the subject report found the men with shaved heads are more dominant(占优势的) than their hairy counterparts(对应的人).

    The study found that men with thinning hair were viewed as the least attractive and powerful. For those men, the solution could be as cheap and simple as a shave.

    New York image consultant Julie Rath advised her clients to get closely cropped when they start thinning up top. “There is something really strong, powerful and confident about laying it all bare(光秃的),” she said, describing the thinning look as kind of raunchy(不修边幅的).

    Not everyone needs a bare head. Rick Devine, 55, the CEO of Devine Capital Partners, advised executive candidates attracted by their clippers to keep their hair closely cropped, rather than completely shaved. “It is way too much image risk,” he said, “The best thing you can do in a business meeting is to make your look not an issue.”

    Last week, my granddaughter started kindergarten, and I wished her every success. But part of me didn't. I actually wanted her to fail in some ways because I believe that failure can be good for our learning process. Success is proving that you can do something that you already know you can do, or doing something correctly the first time, which can often be a problematic (存在问题的) victory. First-time success is usually a fluke (侥幸). First-time failure, however, is supposed to be the natural order of things. Failure is how we learn.

    In Africa they describe a good cook as “She who has broken many pots.” If you've spent enough time in the kitchen to have broken a lot of pots, probably you know a fair amount about cooking. I once had dinner with a group of cooks, and they spent time comparing knife wounds and burn scars. They knew how much credibility (可信) their failures gave them.

    I earn my living by writing a daily newspaper column. Each week I know that one column I write is going to be the worst column. I try my best every day. I have learned to love that column. A successful column usually means that I am discussing my familiar topic, writing in a style I am used to or saying the same things as anyone else but in a better way.

    My younger daughter is a trapeze artist (荡秋千演员). She spent three years practising a show, and she did it successfully for years. There was no reason for her to change it but she did anyway. She said she was no longer learning anything new and she was bored. And if she was bored, there was no point in subjecting (使……服从于) her body to all that stress. She risked failure and great public embarrassment in order to feed her soul.

    My granddaughter is a perfectionist. She will feel her failures, and I will want to comfort her. But I will also, I hope, remind her of what she learned, and how she can do better next time. I hope I can tell her, though, that it's not the end of the world. Indeed, with luck, it is the beginning.

    You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?

    Jane Addams (1860-1935)

    Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community(社区) by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American women to win the Nobel Peace Prize.

    Rachel Carson (1907-1964)

    If it weren't for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world's lakes and oceans.

    Sandra Day O'Connor (1930-present)

    When Sandra Day O'Connor finished third in her class at Stanford Law School in 1952, she could not find work at a law firm because she was a woman. She became an Arizona State Senator(参议员) and in 1981, the first woman to join the US Supreme Court（高等法院）. O'Connor gave the deciding vote in many important cases during her 24 years on the top court.

    Rosa Parks (1913-2005)

    On December 1, 1955, in Montgomery, Alabama, Rosa Parks would not give up her seat to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott. (抵制行动) It lasted for more than a year, and kicked off the civil-rights movements. "the only tired I was, was tired of giving in." said Parks.

Both humans and animals have enemies. 11 is easy for us to know the difference between our friends and our enemies. But can other animals do the same? Elephants can! They can use their sense of vision and smell to tell the difference between people who mean a threat and those who do not. In Kenya, researchers find that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men hunt animals and thus mean a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants.

In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants noticed the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they noticed the smells of either clean clothing or clothing worn by a Kamba man.

Clothing color also plays a role. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted angrily toward the red clothing.

The researchers believe that the elephants' emotional reactions arc due to their different senses of smell and sight. Smelling a possible danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and become aggressive.

    Sometimes just when we need the power of miracles to change our beliefs, they materialize in the places we'd least expect. They can come to us as a great change in our physical reality or as a simple coincidence in our lives. Sometimes they're big and can't be missed. Other times they're so subtle that if we aren't aware, we may miss them altogether. They can come from the lips of a stranger we suddenly and mysteriously meet at just the right instant. If we listen carefully, we'll always hear the right words, at the right time, to dazzle (目眩) us into a realization of something that we may have failed to notice only moments before.

    On a cold January afternoon in 1989, I was hiking up the trail that leads to the top of Egypt's Mt. Horeb. I'd spent the day at St. Catherine's Monastery and wanted to get to the peak by sunset to see the valley below. As I was winding up the narrow path, I'd occasionally see other hikers who were coming down from a day on the mountain. While they would generally pass with simply a nod or a greeting in another language, there was one man that day who did neither.

    I saw him coming from the last switchback on the trail that led to the backside of the mountain. As he got closer, I could see that he was dressed differently from the other hikers I'd seen. Rather than the high-tech fabrics and styles that had been the norm, this man was wearing traditional Egyptian clothing. He wore a tattered, rust-colored galabia and obviously old and thick-soled sandals that were covered in dust. What made his appearance so odd, though, was that the man didn't even appear to be Egyptian! He was a small-framed Asian man, had very little hair, and was wearing round, wire-rimmed glasses.

    As we neared one another, I was the first to speak, "Hello," I said, stopping on the trail for a moment to catch my breath. Not a sound came from the man as he walked closer. I thought that maybe he hadn't heard me or the wind had carried my voice away from him in another direction. Suddenly he stopped directly in front of me on the high side of the trail, looked up from the ground, and spoke a single sentence to me in English, "Sometimes you don't know what you have lost until you've lost it." As I took in what I had just heard, he simply stepped around me and continued his going down the trail.

    That moment in my life was a small miracle. The reason is less about what the man said and more about the timing and the context. The year was 1989, and the Cold War was drawing to a close. what the man on the trail couldn't have known is that it was during my Egyptian pilgrimage (朝圣), and specifically during my hike to the top of Moses's mountain, that I'd set the time aside to make decisions that would affect my career in the defense industry, my friends, my family, and, ultimately, my life.

    I had to ask myself what the chances were of an Asian man dressed in an Egyptian galabia coming down from the top of this historic mountain just when I was walking up, stopping before me, and offering his wisdom, seemingly from out of nowhere. My answer to my own question was easy: the odds were slim to none! In a meet that lasted less than two minutes on a mountain halfway around the world from my home, a total stranger had brought clarity and the hint of a warning, regarding the huge changes that I would make within a matter of days. In my way of thinking, that's a miracle.

    I suspect that we all experience small miracles in our lives every day. Sometimes we have the wisdom and the courage to recognize them for what they are In the moments when we don't, that's okay as well. It seems that our miracles have a way of coming back to us again and again. And each time they do, they become a little less subtle, until we can't possibly miss the message that they bring to our lives!

    The key is that they're everywhere and occur every day for different reasons, in response to the different needs that we may have in the moment. Our job may be less about questioning the extraordinary things that happen in our daily lives and more about accepting the gifts they bring.
