【推荐2】An old English saying says, “Laughter is the best medicine.” One person who certainly would have agreed with this is Norman Cousins.

Norman Cousins worked for a magazine called Saturday Re-view for almost forty years. He also wrote articles about peace, traveling to many different countries to share his ideas.

In the 1960s, after returning to the United States from a busy and tiring trip to Europe, Mr. Cousins got sick. In less than a week after he got back, he could not stand. Every move that he made was painful. He was not able to sleep at night. The doctors told Mr. Cousins that they did not know how to cure (治 疗) his problem and he might never get over the illness. Mr. Cousins, however, refused to give up hope.

Mr. Cousins thought that the illness could be caused by unhappy thoughts. He did not want to take medicine to cure himself. Instead, he felt that happy thoughts or laughter might cure his illness.

He began to experiment on himself while still in the hospital by watching comedy shows on television. Mr. Cousins quickly found that ten minutes of real laughter during the day gave him two hours of sleep without pain at night.

Deciding that the doctors could not help him, Mr. Cousins left the hospital and checked into a hotel room where he could continue his experiments with laughter. For eight days, Mr. Cousins rested in the hotel room watching comedy shows on television, reading funny books, and sleeping whenever he felt tired. Within three weeks, he felt well enough to have a holiday to Puerto Rico, where he began running on the beach for exercise. After a few months, Mr. Cousins was able to carry on his work. He had laughed himself back to health.

【推荐1】Missing out on deep sleep can leave you feeling slow-acting and sensitive in the morning, but the consequences don’t necessarily end there. Over time, too little deep sleep may also do harm to your heart by contributing to high blood pressure, a new study suggests.

Healthy young and middle-aged adults spend about 25 percent of their sleeping hours in the stages known as deep sleep. This sleep stage has been shown to be important for memory and other mental performance. The new study adds to the growing evidence that deep sleep is also essential to our metabolism (新陈代谢) and heart health.

The research should be considered “exploratory”, and it doesn’t prove a direct link between sleep patterns and high blood pressure. But it suggests that an important aspect of successful aging is the preservation of good sleep quality”. Older people tend to get less deep sleep as they age, find fighting this natural decline —through healthy sleep habits, for example—could be an “extraordinarily important strategy” for heading off high blood pressure.

Sleep problems have been linked to high blood pressure before. Sleep apnoea, a disorder in which a person wakes up struggling for breath time and time again, is strongly linked to high blood pressure, though it’s not clear whether the disorder causes high blood pressure.

Susan Redline, a professor of sleep medicine, says going to bed and waking up at the same time each day, especially keeping away from alcohol and tobacco before going to bed and other good “sleep hygiene (卫生)” can help people sleep longer.

However, the researchers followed the men’s sleep only on a single nights, and they likewise measured blood pressure just once or twice. Therefore, the study failed to rule out factors besides sleep quality, such as diet or medical conditions, which may independently contribute to high blood pressure. More research will be needed to address these shortcomings, the study notes. Nor is it clear whether habitual sleep loss has long-term effects on overall sleep quality and deep sleep.

【推荐3】One billion teenagers and young adults around the world risk losing their hearing by listening to loud music, according to the World Health Organization. The U. N. agency is asking young people to turn down the volume（音量） to prevent great damage to their hearing.

Many people believe the sound being louder is better if they are listening to rock and roll. But experiencing really loud music, even really good music, can have a serious effect on the hearing.

Studies in middle- and high-income countries show nearly 50 percent of teenagers and young adults aged 12 to 35 listen to unsafe levels of sound. They are listening on their personal audio devices as well as at concerts, nightclubs and other entertainment places.

But what is an unsafe level of sound?

The WHO says there can be many kinds of unsafe levels of sound. It depends on how loud the sound is and how long you listen to it. Unsafe levels of sound can mean noise levels of 85 decibels（分贝） for eight hours a day or 100 decibels for just 15 minutes.

Doctors say there are simple measures to protect people from unsafe sound levels. Young people who wear earplugs（耳塞） during concerts can enjoy music at 90 decibels as much as they can at 110 decibels. But they admit that earplugs may not look very cool. A common sense suggestion is to turn down the volume on their personal audio devices. The WHO also advises young people to limit their use of such devices to less than one hour a day. It reminds people to use their technology to stay safe. Smartphone apps can help t monitor safe listening levels.

The U. N. agency estimates 360 million people suffer hearing loss linked to many causes, including noise, genetic conditions, infectious diseases and aging. It notes half of all cases of hearing loss are avoidable.

【推荐1】While children are dogs—loyal and affectionate (情深的)—teenagers are cats. It′s so easy to be a dog owner. You feed it, train it, and boss it around. It puts its head on your knee and gazes at you as if you were a Rembrandt painting. It bounds indoors with enthusiasm when you call it.

Then around age 13, your adoring little puppy turns into a big old cat. When you tell it to come inside, it looks amazed, as if wondering who died and made you emperor. Instead of dogging your doorsteps, it disappears. You won′t see it again until it gets hungry―then it pauses on its sprint through the kitchen long enough to turn its nose up at whatever you′re serving. When you reach out to ruffle its head, in that old affectionate gesture, it turns away from you, then gives you a blank stare, as if trying to remember where it has seen you before.

You, not realizing that the dog is now a cat, think something must be desperately wrong with it. It seems so antisocial, so distant, sort of depressed. It won′t go on family outings.

Since you are the one who raised it, taught it to fetch and stay and sit on command, you assume that you did something wrong. Flooded with guilt and fear, you redouble your efforts to make your pet behave.

Only now you′re dealing with a cat, so everything that worked before now produces the opposite of the desired result. Call it, and it runs away. Tell it to sit, and it jumps on the counter. The more you go toward it, wringing your hands, the more it moves away.

Put a dish of food near the door, and let it come to you. But remember that a cat needs your help and your affection too. Sit still, and it will come, seeking that warm, comforting lap it has not entirely forgotten. Be there to open the door for it.

One day your grown-up child will walk into the kitchen, give you a big kiss and say, “You′ve been on your feet all day. Let me get those dishes for you.”

Then you′ll realize your cat is a dog again.

【推荐2】When my son Connor started walking, we knew something was wrong. He was 17 months old, and he walked on his tiptoes. Soon Connor's muscles began to lose strength. At three he showed signs of upper-body weakness, by five he couldn't hold his head upright, and by the first grade, he would need a wheelchair. As the day passed, he tired and couldn't hold a pencil to write. Within two years, he would be too tired to feed himself dinner. Everyone was puzzled. Physically, his body was twisted, but he was mentally perfect. We ran tests after tests, but no definite answer.

Finally, in 2004, we consulted Dr. Shawn, a geneticist, who said that Connor's symptoms had signs of dystonia(肌张力障碍) —a very rare genetic disorder, and a possible cure was L-dopa. Though there was possible side effects of the treatment, when Connor’s condition worsened, I had little choice.

Dr. Jacobs, a neurologist(神经学家), gave Connor the first dose (一次剂量的药) on June 21, 2007, when he was nine years old. The next morning, when I went in to wake him up, I found him kneeling on his bed — he hadn't done that since he was learning to walk. He shouted, “Look at me, Mom!” Connor was excited.

Over the next few days, Connor kept getting stronger. He held his upper body much straighter after the first week. A few weeks later, he “furniture-walked,” supporting himself on chairs and couches. He later walked holding both of my hands, then just one hand. And on August 13, he walked across my mother’s living room by himself.

I could now believe the unbelievable: The medicine was working. The child who had been too weak to feed himself dinner was walking. Since then, every year on June 21, we celebrate Dopa Day with a cake and presents, for it’s Connor’s second “birthday,” and it marks the best day of my life.

【推荐3】It’s really true what people say about English politeness: it’s everywhere. When squeezing(挤) past someone or passing through a crowd in a narrow place, people say “sorry”. When getting off a bus, English passengers say “thank you” rather than the driver. In Germany, people would never dream of doing these things. After all, squeezing past others is sometimes unavoidable(不可避免的), and the bus driver is only doing his job. I used to think the same way, without questioning it, until I started traveling to the British Isles and came to appreciate(欣赏) some more polite ways of communicating with people, and here are some more polite ways of interacting with people in UK.

People thank each other everywhere in England, all the time. When people buy something in a shop, customer and shop assistant in most cases thank each other twice or more. In Germany, it would be surprising to hear more than one thank you in such a conversation. British students thank their lecturers when leaving the room. English employers thank their employees for doing their jobs, which is different from Germans, who would normally think that paying their workers money is already enough.

Another thing I observed during my stay was that English people rarely criticize(批评) others. Even when I was working and mistakes were pointed out to me, my employers repeated several times but none of their explanations were intended as scolding me. It has been my impression that by avoiding scolding, English people are making an effort to make others feel comfortable. This also is showed in other ways. British men still open doors for women, and British men are more likely to treat(请客) women to a meal than German men. However, I do need to point out here that this applies(适用于) to English men a bit more than it would to Scottish men! Yes, the latter are a bit mean(吝啬的).
