Beauty has always been regarded as something praiseworthy. Almost everyone thinks attractive people are happier and healthier, have better marriages and have more respectable jobs. Personal advisors give them better advice for finding jobs. Even judges are softer on attractive defendants. But in the executive(主管) circle, beauty can become a liability.

    While attractiveness is a positive factor for a man on his way up the executive ladder, it is harmful to a woman.

    Handsome male executives were considered as having more honesty than plainer men; effort and ability were thought to lead to their success.

    Attractive female executives were considered to have less honesty than unattractive ones; their success was connected not with ability but with factors such as luck.

    All unattractive women executives were thought to have more honesty and to be more capable than the attractive female executives. Interestingly, though, the rise of the unattractive overnight success was connected more to personal relationships and less to ability than that of the attractive overnight success.

    Why are attractive women not thought to be able? An attractive woman is considered to be more feminine and an attractive man more manly than the less attractive ones. Thus, an attractive woman has an advantage in traditionally female jobs, but an attractive woman in a traditionally manly position appears to lack the "manly" qualities required.

    This is true even in politics. "When the only clue is how he or she looks, people treat men and women differently," says Anne Bowman, who recently published a study on the effects of attractiveness on political candidates. She asked 125 undergraduate students to rank two groups of photographs, one of men and one of women, in order of attractiveness. Then the students were told the photographs were of candidates for political offices. They were asked to rank them again, in the order they would vote for them.

    The results showed that attractive males completely defeated unattractive men, but the women who had ranked most attractive unchangeably received the fewest votes.

    My mother raised me as best as she could, taking on odd jobs in the neighborhood for money. Still without a father to tell me how to act and what was expected of me, I felt lost. I wandered for years and got involved with tough guys on the East Side of New York. They would fight madly over a dropped coin. They would steal to get what they wanted. I wanted to be like them.

    It was lucky for me that I left the city and entered a world of discipline (纪律), after following my mother's advice. During three years of military service, I had time to rethink my life, and my thoughts often ran to my mother. I realized suddenly just how much of a heartache I must have been to her, how little I had noticed her suffering. When my father left this world, my mother was completely alone. To support us, my mother cleaned apartments and took in washing and ironing from the neighbors. And as she worked hard at this labor, she kept her head high. Each week she would bring a pile of books home from the library and read to us. My mother had wanted nothing more, than for me to turn into an honest responsible man. But I had acted against her. Finally, almost too late I had the sense to feel shame.

    Ten years passed and I returned to the apartment on the East Side. I knew I wouldn't fall back in with the wrong people, although I still wasn't sure where I was heading. My mother, I could tell, was worried about me. In my neighborhood, to become a police officer or a firefighter was a mark of significant social success and achievement. For me it was an opportunity for a real start in life. I wondered if I was up to it, but I knew that it was time to try. When I found myself in the big hall raising my hands to take the firefighters oath (誓言) of office, my mother was sitting a few rows behind with a smile of relief. She knew that at last I was off on life's road and moving steadily. Her smile said, “My job is finally done.”

    Long before iPhone, the cigarette was the companion of choice for restlessness. And long before Facebook and WeChat, it was tobacco that promised to better your social life. Now, quitting smartphones has become the new quitting smoking.

    Of course, technology does not yellow your teeth, cause disease or lead to cancer. But some individuals are so concerned that device addiction is damaging their mental health. In order to reduce their dependence, even in Silicon Valley, people are turning off the messages that constantly buzz for their attention, banning smartphones from the bedroom and, curiously, changing the colors on their screens to a less tempting scale of gray.

    The big tech companies will have to work out how to respond to this new generation of quitters. Facebook is the first to go public with its attempt, hoping its recent move can make the social network more homely.

Last year the tech industry got a bad name —Big Tech—with unfortunate echoes of other industries that have faced fierce opposition, including Big Tobacco. Like them, the tech industry has to reduce concern from a new generation of activist shareholders （股东） that are questioning its role in the world. These campaigns are never as fierce as those faced by Big Tobacco. In the 1990s, socially responsible investors refused to put money in tobacco stocks.

    It is far difficult for investors to challenge Big Tech and hard to separate the good these companies do in the world-connecting old friends and giving space for people to share their ideas-from the bad. In the meantime, stopping using technology remains problematic. In The World Without Mind: The Existential Threat of Big Tech, Franklin Foer argues that tech should be seen in a similar way to junk food: a convenience that some reject for more continuing nutrition.

    So we need to do more to turn the tide. In the same way that public service announcements made smoking around your children taboo （禁忌）, we can warn parents against losing themselves in their smartphones while taking care of kids. We can also create no-smartphone zones at dinner. Eventually smartphones could be banned from all public places and help us give our attention to the people around us instead.

    "An apple a day keeps the doctor away." Similarly, if we drink a little more water every day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fiber, without giving us too much fat and sugar. But why is water important?

The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.

    Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems start as a result of dehydration (脱水)-—a lack of water in the body. Most people are dehydrated at least some of time, although they probably don't know it. It is surprising to learn that if we feel thirsty, we are already in the first stage of dehydration. In fact, we are advised to drink water before we feel thirsty.

    These doctors think that health problems such as headaches, high blood pressure and asthma (哮喘) could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water. There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.

By 11:00, Gopamma knew something was wrong. Her husband, Hanutha, should have returned from collecting firewood an hour before. Gopamma sent for her son, who gathered a search party and headed to Bandipur Tiger Reserve, a nearby national park in south-western India. Just inside the forest, they discovered Hanutha's half-eaten remains. The tiger that killed him was still sitting next to the body.

In the face of her husband's death, Gopamma struggled not only with grief but economic hardship. Her son had to drop out of university. "My life was much better when my husband was alive," she says. "My older son could have studied, but now both of my sons have to work. I feel insecure and dependent. "

Despite all this, Gopamma feels no hate toward the tiger that killed her husband. Like many Hindus in India, she views humans and creatures, each with an equal right to existence. Her husband's death, she says, has nothing to do with the fact that the government is trying to save tigers: "This was my fate."

Rural Indians are unique in the world for their high tolerance for co-existing with potentially deadly wildlife. "You don't find this in other cultures," says Ullas, a biologist at the Wildlife Conservation Society and a leading expert on tigers. "If this kind of thing happened in Montana or Brazil, they'd wipe out everything the next day. "

The country holds just 25% of total tiger habitat, but accounts for 70% of all remaining wild tigers, or around 3, 000 animals today. Success does not come without cost, however. They still have a lot of difficulties with tigers breaking into human-dominated places in certain parts of India, livestock(牲畜) are killed and sometimes so are people.

Some animal activists think that there are too few tigers left in the wild, so even one shouldn't be killed. Tigers are treasures, we'd better live with them together.
