It all began with a stop at a red light.

    Kevin Salwen was driving his 14-year-old daughter,Hannah,back from a sleepover in 2006.While waiting at a traffic light,they saw a black Mercedes Coupe on one side and a homeless man begging for food on the other.

    "Dad,if that man had a less nice car,that man there could have a meal," Hannah protested.The light changed and they drove on,but Hannah was too young to be reasonable.She pestered（纠缠）her parents about inequity,insisting that she wanted to do something.

    "What do you want to do?" her mom responded. "Sell our house?"

    Warning!Never suggest a grand gesture to an idealistic teenager.Hannah seized upon the idea of selling the luxurious family home and donating half the proceeds（收入）to charity,while using the other half to buy a more modest replacement home.

    Eventually,that's what the family did.The project—crazy,impetuous（鲁莽的）and absolutely inspiring—is written down in detail in a book by father and daughter scheduled to be published next month: The Power of Half.It's a book that,frankly,I'd be nervous about leaving around where my own teenage kids might find it.An impressionable child reads this,and the next thing you know your whole family is out on the street.

    At a time of enormous needs in Haiti and elsewhere,when so many Americans are trying to help Haitians by sending everything from text messages to shoes,the Salwens offer an example of a family that came together to make a difference—for themselves as much as the people they were trying to help.In a column a week ago,it described neurological（神经生物学的）evidence from brain scans that unselfishness lights up parts of the brain normally associated with more primary satisfaction.The Salwens' experience confirms the selfish pleasures of selflessness.

    Mr.Salwen and his wife,Joan,had always assumed that their kids would be better bigger house.But after they downsized,there was much less space to retreat to,so the family members spent more time around each other.A smaller house unexpectedly turned out to be a more family-friendly house.

    Last week my youngest son and I visited my father at his new home in Tucson, Arizona. He moved there a few years ago, and I was eager to see his new place and meet his friends.

My earliest memories of my father are of a tall, handsome successful man devoted to his work and family, but uncomfortable with his children. As a child I loved him; as a school girl and young adult I feared him and felt bitter about him. He seemed unhappy with me unless I got straight A's and unhappy with my boy- friends if their fathers were not as "successful" as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.

    On the first day of my visit, we went out with one of my father's friends for lunch at an outdoor cafe. We walked around that afternoon, did some shopping, ate on the street table, and laughed over my son's funny facial expressions. Gone was my father's critical air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?

    The next day my dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him than at that moment. After so many years, I'm at last seeing another side of my father. And in so doing, I'm delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he was.

Importance of College Education

    During the high school career, students may begin to question the importance of a college education. They might find themselves asking, “Why is it important to go to college?” The answer is that, more than ever, college graduates enjoy much greater opportunities available to them than those who have not received a college education.

    For many high school students, being able to immediately generate an income after graduation is an appealing thought. They may also be affected by the rising cost of tuition, and while it is true that a higher education may be one of the largest expenses you will ever face, the importance of a college education has become quite evident in terms of earning potential within today's economy.

    Why should you go to college? One important answer to this question is more opportunity. As opposed to generations of the past, high school graduates today are unable to obtain high-paying jobs that were once available. The U.S. has been transformed from a manufacturing-based economy to an economy based on knowledge, and the importance of a college education today can be compared to that of a high school education forty years ago. It serves as the gateway to better options and more opportunity.

    There are additional reasons as to why it is important to go to college. When students experience a post secondary education, they have the opportunity to read books and listen to the lectures of top experts in their fields. This encourages students to think, ask questions, and explore new ideas, which allows for additional growth and development and provides college graduates with more opportunities in the job market over those who have not experienced a higher education.

    The importance of a college education is also stressed because of the opportunity to gain valuable resources during the study. The more connections which are collected during your college career, the more options you will have when you begin your job search. Once you have ended your job search and have started your career, however, the importance of a college education has not been exhausted. Having a college degree often provides for greater promotion opportunity.

    So, why should you go to college? The reasoning does not begin and end with the job aspect. A good education is beneficial from many different viewpoints, and though the importance of a college education is quite evident for many high school students, what is often not as clear is how they will pay for that education.

    It's common knowledge that sleep problems can be caused by things such as stress, anxiety, or even using a smartphone before bedtime. But recently, a team of researchers discovered that genes could also be a cause of sleepless nights.

    The scientists, from Rockefeller University in New York, US, found that delayed sleep phase disorder（DSPD，睡眠相位后移综合症）, a condition that affects one's sleeping patterns, is passed down via a mutated（突变的）gene. DSPD sufferers wake up later and go to bed later than the average person. To come to their conclusion, the team studied a 46-year-old woman who is only usually able to fall asleep at 2 or 3 in the morning. It was discovered that the woman's body produces the hormone that helps her sleep at night up to 7 hours later than regular sleepers. The scientists found this was caused by a mutation in one of the woman's genes, one that helps regulate the “body clock”.

    Some of the woman's family members were also found to share the same mutation—and the same sleeping problems –leading the scientists to believe that sleep troubles are passed down through the generations.

    However, having this mutation doesn't mean you automatically have sleep problems. The team also found two people who had the mutation but reported no problems with their sleep.

    But while this is an interesting discovery, it offers no help to those who can't fall asleep at night—although there are a few things you could try to help you sleep earlier.

    BBC journalist Michael Mosley produced a TV documentary in May in which he talked about his battle with insomnia（失眠）and the techniques he used. “I avoid social media for at least an hour before bed, I do mindfulness exercises, and if I wake up in the middle of the night, I read a book for an hour or so,” he wrote in an article for the Radio Times.

    The annual World Economic Forum 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 (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.
