When I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived on a farm, in the winter especially, we wear quite out off from the outside world. As soon as I left school, I packed my bags and moved to the capital.

    However, I soon discovered that one big disadvantage is money. It costs so much to go out, not to mention basics like food and housing. Another disadvantage is pollution. I suffer from asthma(哮喘), and the air is so bad that I am afraid to go outside. Then there is the problem of traveling round. Although I have a car, I seldom use it because of the traffic jams. One choice is to go by bicycle, but that can be quite dangerous.

    Of course there are advantages. First, there is so much to do in the city, whatever you tastes in culture or entertainment(娱乐活动). Besides, there are wonderful jobs and greater chances of moving to a more important job or position. Finally, if you like shopping, the variety of goods is very surprising — and, what is more, shops are often only a short walk away.

    Is life better then, in the city? Perhaps it is, when you are in your teens(十几岁) or twenties. However, as you get older, and especially if you have small children, the peace of the countryside may seem preferable. I certainly hope to move back there soon.

    Are you content with the shape of your nose? If not, the climate may be to blame, not your parents.

    This is according to a recent study carried out by scientists from Pennsylvania State University, US. They found that climate played a key role in shaping our noses. The findings were based on an examination of the size and shape of noses of 476 people from four regions — West Africa, East Asia, South Asia and Northern Europe, using 3D facial imaging technology.

     “People have thought for a long time the difference in nose shape among humans across the world may have arisen as a result of natural selection because of climate,” Arslan Zaidi, one of the lead authors of the study, told the Guardian. But while previous studies were based on measurements from human skulls(头骨), Zaidi and his team looked at nose shape itself.

    The result showed that wider noses are more common in warm and humid climates, while narrower noses are more common in cold and dry climates. That, Zaidi said, could be because narrower nasal passages (鼻道) help to increase the wet content of air and warm it, which is easier on our lungs. This, in turn, led to a gradual decrease in nose width in populations living far away from the equator (赤道).

    More study is still needed to test the link between climate and nose shape, but Zaidi believes the current findings are valuable in understanding potential health issue. “As we become more of a global community, we are going to come across climates that we are not adapted to,” he told the Guardian. This means moving to a very different climate might increase the risk of breathing problems.

    However, he added, “This may not be necessarily true for various reasons such as of modem medicine and the fact that our current climate is very different from what it used to be.”

Dear Maya Shao­ming,

    To me, June 6, 1990 is a special day. My long­awaited dream came true the minute your father cried, "A girl！"You, little daughter, are the link to our female line, the legacy of another woman's pain and sacrifice 31 years ago.

    Let me tell you about your Chinese grandmother. Somewhere in Hong Kong, in the late fifties, a young waitress found herself pregnant(怀孕) by a cook. She carried the baby to term, suffered to give it birth, and kept the little girl for the first three months of her life. I like to think that my mother—your grandmother—loved me and fought to raise me on her own, but the daily struggle was too hard. Worn down by the demands of the new baby and perhaps the constant threat of starvation, she made the painful decision to give away her girl so that both of us might have a chance for a better life.

    Having a baby in her unmarried state would have brought shame on the family in China, so she probably kept my existence a secret. Once I was out of her life, it was as if I had never been born. And so you and your brother and I are the missing leaves on a family tree.

    Do they ever wonder if we exist?

    Before I was two, I was adopted by an Anglo couple. I grew like a wild weed and grasped all the opportunities they had to offer—books, music, education, church life and community activities. In a family of blue­eyed blonds, though, I stood out like a sore thumb. Moody and impatient, burdened by fears that none of us realized resulted from my early years of need, I was not an easy child to love. My mother and I conflicted countless times over the years, but gradually came to see one another as real human beings with faults and talents. Lacking a mirror image in the mother who raised me, I had to seek my identity as a woman on my own. The Asian American community has helped me regain my double identity.

    But part of me will always be missing: my beginnings, my personal history, all the delicate details that give a person her origin. Nevertheless, someone gave me a lucky name "Siu Wai". "Siu" means "little", and "Wai" means "clever". Therefore, my baby name was "Clever little one". Who chose those words? Who cared enough to note my arrival in the world?

    I lost my Chinese name for 18 years. It was Americanized for convenience to "Sue". But like an ill­fitting coat, it made me uncomfortable. I hated the name. But even more, I hated being Chinese. It took many years to become proud of my Asian origin and work up the courage to take back my birth name. That, plus a little knowledge of classroom Cantonese, is all the Chinese culture I have to offer you. Not white, certainly, but not really Asian, I try to pave the way between the two worlds and bridge the gap for you. Your name, "Shao­ming", is very much like mine—"Shao" means "little". And "ming" is "bright", as in a shining sun or moon. Whose lives will you brighten little Maya? Your past is more complete than mine and each day I cradle you in your babyhood, generously giving you the loving care I lacked for my first two years. Sweet Maya, it doesn't matter what you "become" later on. You have already fulfilled my wildest dreams.

    I love you,

Mummy

    When we do the same movements with our bodies over and over again, we overuse some muscles. And that overuse can lead to strain(紧张)and injury. Sometimes those problems can come from doing sports. But exercise experts say they are now seeing another cause for muscle problems: hand-held technology devices(设备).

    Staring down at your phone or tablet for long periods of time puts great tension on your neck and spine(脊椎). Many people who use tech devices also bend their shoulders forward. Experts say this posture(姿势)puts strain on the entire upper body. Muscle strain linked to hand-held technology has become such a common condition that it now has a name: tech neck.

    Kimberly Fielding, an exercise teacher in New York City, explains that constantly looking down at our devices creates an unnatural bend in our spine. This can cause nerve pain and other problems. “A lot of the curves of the neck can change, so instead of the neck spine going inward, the curve can be a little bit different and it causes nerve pain and disc herniation(椎间盘突出)and different muscle tension headaches — different things that really can reduce quality of life.”

    Fielding created a class to directly solve the problem of tech neck. The class uses different exercises to release tension in the upper body and strengthen back and neck muscles. Fielding says these exercises may feel uncomfortable in the beginning because the neck muscles may have become weak.

    However, you don't need to take a class like Fielding's. You can take simple steps to improve tech neck. For a quick fix, hold your phone at eye level. At the same time, take breaks from using your technology by standing up and stretching your legs often. Also, give your eyes a break by closing them throughout the day.

    A new study has found the amount of antibiotics(抗生素)given to farm animals is expected to increase by two-thirds over the next 15 years. Researchers are linking the growing dependence on the drugs to the increasing need for meat, milk and eggs. However, the drugs could quicken the development of antibiotic-resistant infections(感染). Such infections are already a major public, health concern in the United States.

    The World Health Organization notes when people stop living in poverty(贫困), the first thing they want to do is eat better, rather than earn more money. For most people, that means their diet should contain more meat. With the rapid development of Asia, people there are eating nearly four times as much meat, milk and other milk products as they did 50 year ago.

    To meet the need, farmers have put many animals into smaller spaces. As the animals are crowded together, the easiest way to deal with some of the problems of crowding is to give them antibiotics. It's clear that antibiotics help animals stay healthy in a crowded environment and grow faster. But bacteria can develop resistance to the drugs gradually.

    Nowadays, doctors find antibiotics that once worked against the infections no longer work. The bacteria have learned ways to fight against the drugs. The heavy use of antibiotics in animals is responsible for the growth of antibiotic resistance worldwide. In the United States, at least two million people get drug-resistant infections each year and at least 23,000 die from an infection.

    Europe has banned the use of antibiotics to increase animal growth. And the United States is hoping to persuade farmers to stop using antibiotics for that purpose.

I was ever bullied badly when I was in high school. One kid in particular would try to make me feel worse in every way he knew. For example, he would throw stuff at me constantly, hit me on the head, punch me, call me ugly and stupid, make fun of me and, of course tell me he would beat me up if I ever fought back. It was like his daily mission. And it was my daily mission to just get through the day. What could I say? It made my world very small because that was my main focus—just surviving. Everything else fell by the wayside. Unfortunately, that included any form of social life. So not only was my world tiny, but it was very lonely.

    Looking back to that time, which was about 11 years ago, my biggest mistake was not bringing anyone into that world of mine. I was too proud and embarrassed to get help. I would rather not face the fact that I needed help because in my mind, that would mean that the bully had won. It would also mean that I was weak.

Let me just say this—-bullying someone is a weak choice. The only reason why they come after you is that they don't think you will do anything about it. Does that make anyone strong? Absolutely not. Be stronger. Reach out to a parent, a teacher or a friend for help. Simply admit that you are struggling and need help.

    You can put it like this: Somebody who is weak and trying to build himself or herself up has chosen to do that by putting me down. The only reason why they are doing it is that I am nice and I haven't done anything about it yet. Well, I am through putting up with this. I have basic human rights that they are trying to take away to feel better and that is just not OK. How do I handle this the right way? I don't want the pain cycle to continue and I don't want to become someone I don't want to be.

I will close by saying this—-I am not just surviving. I am just enjoying my life. I graduated from college with honors, by the way. You don't have to wait to live. Do something today.
