I travel a lot in my work, and what I dislike about my job is eating alone. It always makes me feel lonely to see others laughing and talking. So, room service for several nights was a better choice for me.

    After having room service three nights at a hotel in Houston, however, I needed to get out of my room. Although the restaurant opened at 6:30, I arrived at 6:25. The waiter at the front desk made a comment(评论) about my “being there really early”. I explained my dislike of eating alone in restaurants. He then seated me at a lovely table and asked me whether I would mind if he sat down with me for a while.

    I was glad! He sat and talked with me about his career goals and the difficulty of being at work on nights, weekends and holidays. He said he hadn't enough time to be with his family. After 15 minutes, he saw some customers at the front desk and excused himself. I noticed that before he went to the front desk, he stopped in the kitchen for a moment.

    Then another waiter came out of the kitchen and had a wonderful chat with me. Before I left that night, some other waiters, even the cook, had come out of the kitchen and sat with me!

    When I asked for my bill about one hour later, all the people who had sat down with me came over in a big group to my table, and presented me with a red rose. And I cried! What had begun as a lonely night ended as a beautiful experience.

The Diet Zone: A Dangerous Place

    Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.

    Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word “diet” in food labels.

    On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don't have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.

    The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients. Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemicals that go into diet products are potentially dangerous.

    Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological and physical harm that comes from using them.

    Women in northern European nations are closest to equality with men on wages, education, health and education. That is the finding of a report by the World Economic Forum. The United States ranked 28th. On Friday, President Barack Obama announced the government will require large businesses to report how much they pay men and women. The data will be used to target companies that pay women less to do the same jobs.

    According to the World Economic Forum report, women worldwide continue to lag behind men on wages. Based on current trends, they will need 126 years to catch up, according to the report. Women are making progress. But they still only earn what men did 10 years ago, say the report's authors. The report measures the gender gap for women in 145 nations for health, education, economic opportunity, and political power. Women have not achieved equality in any of the 145 nations included in the survey, says the report.

    Women came closest to equality in four Northern European nations – Iceland, Norway, Finland and Sweden. Ireland ranks No. 5. At the bottom of the women's gender ratings are Yemen, Pakistan, Syria, Chad, Iran and Jordan.

    More women than men are attending colleges in 97 nations. But women make up a majority of skilled workers in only 68 nations. Women control the majority of government and political positions in only four.

    At last week's World Economic Forum in Davos, Switzerland, Sheryl Sandberg, chief operating officer at Facebook, spoke about gender equality. “The reason to work towards equality – whether woman or man – is that it is better for you,” Sandberg said. “We should be doing this not because it's the right thing, but because it's the smart thing. Do it because it will help you.” The World Economic Forum completed its worldwide 2015 gender gap survey in November.

    Imagine a brand-new, magical pill which can measurably improve your memory, overall cognitive (认知的) performance, ability to learn new information, mood, ability to handle problems and more. Would you buy it?

    Yeah, yeah, you saw this coming: That pill exists, but not in pill form. You can have all of those benefits for free, and all it takes is going to bed a little bit earlier. So what are we to do to get a better night's sleep?

    First, learn how much sleep you need. Generally, if you're waking up tired, you're not getting enough. However, the gold standard of eight hours per night might not be right for you. A study from 2015 brought into question whether we need that magical number, so following your body is the best way to figure out the right rhythm. The only real guideline is to get as much sleep as you need to feel refreshed and energized the next day.

    Next, figure out your body's natural rhythm. Maybe after years of trying, you need to acknowledge that you're just not a morning person. And that's perfectly fine! Click the link and take the quiz to find out what kind of sleeper you are, and don't fight your body's natural sleep tendencies.

    Last, keep a consistent sleep schedule. This can be the most important part of your overall sleep quality We're all equipped with circadian clock (生物钟), which s that internal 24-hour timer that naturally tells us when to sleep, and the best way to getting rest and feeling rested is to keep this consistent. Fall asleep and wake up at the same time every day, and try to build as much regularity into your schedule as possible. And don't forget to keep your bedroom cool.

    The annual World Economic Forum (经济论坛) took place in Davos, Switzerland, in Jan. 23-26, 2018. What did Chinese entrepreneurs (企业家) speak in the forum? Are there some quotable quotes for you?

    Jack Ma, founder and executive chairman of Alibaba Group

    "I think globalization cannot be stopped — no one can stop globalization, no one can stop trade. If trade stops, the world stops. Trade is the way to dissolve (溶解，结束) the war not cause the war," said Ma in Davos, "Google, Facebook, Amazon and Alibaba — we are the luckiest companies of this century. But we have the responsibility to have a good heart, and do something good."

★Richard Liu, founder and chief executive officer of JD

    "Business is not only a way to make money but also a way to contribute yourself, to help people," Liu said in a speech in Davos. "How can we face the fractured (分化的)world? That's the topics of the Davos this year. I think a very important thing in business is cooperation. If we can unite, work together, if we work very closely, I think we can bring more hope to the people and we can build more trust between the people, countries and companies and partners," he said.

    Jane Sun, CEO of Ctrip

    "Tourism is a sunrise industry. Since I entered Ctrip, every year there are new comers, which, first of all, shows that tourism is booming." Sun told Sina.com in Davos. "We invested heavily in ABC. A refers to AI, B is big data, and C is cloud computing. As we continue to expand overseas, these three will be very good weapons for us. So we think those mean opportunity," she said.

★Hu Xiaoming, president of Aliyun

    "In 2018, people will see the development in various countries more closely connected with cloud computing. More manufacturing enterprises and financial institutions will start to use „cloud', and cloud computing will increase the efficiency of technology and finance," Hu told Xinhua in Davos.

    When you are sitting in the car, do you ever notice the drivers looking over their shoulders or side to side in the car? Well, they are doing this to check their blind spots! Blind spots make driving extremely difficult and increase the potential for car accidents.

    Fourteen-year-old Alaina Gassier from Pennsylvania noticed her mother struggling with blind spots while driving their family car. So she came up with an ingenious solution that won the first place and $ 25,000 in the Broadcom Masters Competition.

    Blind spots are the areas around the car that cannot be directly observed by the driver. There are two kinds of blind spots-on the back of the car that cannot be seen with mirrors, and blind spots at the front of the car as well.

    When a driver is changing lanes, he has to look over his shoulder through the side windows to make sure that there is no vehicle in the blind spot. This invisible area is big enough to hide a car!

    The other blind spot is created in the front by the A-pillar(柱子)-the material on either side on the windshield(挡风玻璃)that holds the glass and forms the frame of the car. In some cars, this pillar can be quite thick. Usually, people or cyclists can be hidden by this pillar.

    Alaina's design was to get rid of the blind spot created by the front A-pillar of the car, the one that helps hold up the windshield.

    She put a camera on the outside passenger side of the car which then sent the photos to a projector above the driver's head. Then, she covered the inside of the pillar in a reflective fabric onto which the image was projected. Basically, her device made the pillar "see through" and removed the blind spot on that side of the car.

    Alaina's solution is very creative and could be improved by using LCD displays that will make it easier to see during day time as well.
