    A couple of weeks ago, a few friends and I had an opportunity to attend a dear friend's wedding in New York. After the wedding and reception, rather accidentally four of us gathered in a hotel room and began to explore the deeper meaning of life and death. What does it mean to live truly? If we are all getting closer to death, is all the material accumulation worth it? It is not exactly the type of conversations one has at a wedding.

    While the answers varied from person to person, I was left with more questions than answers and a feeling of gratefulness to be surrounded by friends who were asking the “right” questions. As the clock kept ticking past 3 a.m., one of the roommates suggested we watch a short film titled “Last Days of Zach Sobiech”. The film is about a teenager's journey through the last days of his incurable illness. The film brought up a lot of mixed emotions but one quote that stood out for me was Zach's simple explanation of happiness, “What makes one happy is seeing someone else smile because you put it there.” By 4 a.m. , there was this energy in the room that had to be shared! With a few packages of post-it notes, we hit the halls of the hotel. We decided to leave short inspirational words on guests' doors, so when they opened their doors few hours later a smile would turn up.

    We ended up sticking post-it notes on all the doors until we ran out of them. The note on the door of the newly-weds properly said, “Where there is love, there is life.”

    Earthquake rescue robots have experienced their final tests in Beijing. Their designers say that with these robots, rescue workers will be able to have more time to save more lives during an earthquake.

    This robot looking like a helicopter（直升机）, is called the detector-bot . It's about 4 meters long, and it took about 4 years to develop the model. Its main functions（作用）are to collect information from the air, and send goods of up to 30kilos, to people stuck in an earthquake.

    This robot has a high quality 360 degree panoramic camera. It can work day and night and will also be able to send the latest pictures from the quake area. Dr. Qi Juntong, Chinese Academy of Science, said, "Unlike other automatic machines, the most important feature of this robot is that it doesn't need a distant control. We just set the information of the earthquake-struck area on it, and then it takes off, and lands by itself. It flies as high as 3,000 meters, and as fast as 100 kilometers per hour. "

This robot has a different function — it can change as the environment changes. Its main job is to search for any signs of life in places where human rescuers are unable to go.

    As well as a detector（探测器）that finds victims（遇难者）and detects poisonous gas, a camera is placed in the 40 centimeter long robot, which can work in the dark.

    Another use for the rescuers is the supply bot, with its 10-meter-long pipe. People who are caught in the ruins will be able to get supplies including oxygen and liquids.

    Experts have said that the robots will enter production, and serve as part of the national earth- quake rescue team as soon as next year.

    How do you get a man to do his share of the housework? If you are like most women, you've faced this question the hard way.

    A man will enjoy a clean, orderly house, but he usually won't make the effort to clean or organise it. This doesn't mean that a woman has to do all the housework; she may have to manage many of the household duties, and request her partner's participation(参与). A woman can often say that men and women should take equal responsibility(责任) for housework.

    Very few men are raised to be fully responsible for housework, and many men look on housework as women's work. On the other hand, most men will readily work around the yard, make repairs and complete projects on weekends or evenings, and it's important that you give your man appreciation(欣赏) for those things, too. Most men will take on a little housework around the house if asked politely. They are even more likely to do housework if they can choose what they want to do, and do it without being monitored(监视).

    Here's the key: men want to feel that they are doing housework either because they want to do a task, or because they simply want to please their women. Men are much less likely to take on household tasks they consider uninteresting and unimportant. In other words, men are likely to do a household task just for the good of the house.

    Based on the State Information Center (SIC)'s definition for a sharing economy, payment for knowledge can be regarded as a process of turning knowledge into commercial products or services. To be specific, people can share their knowledge with others via Internet platforms, meanwhile bringing themselves extra income. These platforms, at the same time, earn their profits on that.

    The year 2016 marked the beginning of knowledge payment in China. An investigation jointly conducted by Guokr and Netease's online platforms shows that 70% of users have paid for online learning; while in 2015, the number was only 26%.

In May, 2016, Zhihu, a Chinese question-and-answer website, launched Zhihu Live (payment sharing). Within three days, these new platforms attracted over one million users. In June, Luo Zhenyu, founder of LUOgic Show, launched Li Xiang's Commercial References on iget(得到网)，and within two days over four million users subscribed; in August, Z/"7m's approval & tip function, Snowball O&A, Lenovo's Zhiliao Q&A came online; in September, Huxiu (虎嗅网)began to provide in-depth reports to VIP payment members. Other paid knowledge platforms such as Ximalaya FM, Douban，have also been developing their knowledge payment services.

    People with a wealth of knowledge and experience in specific areas are the most likely to benefit from payment for knowledge. Senior managers in large multinational companies like Google, financial elites with top university backgrounds and well-known psychologists, can all profit from these online platforms. But the opportunities also favor the ordinary: a body-builder, a girl who traveled around the world, or a student that passed a postgraduate entry exam can all set up a live classroom. One hundred minutes of audio sharing cost ¥ 19.9 or $2.9, and thousands of users might pay and join the course, bringing those with specific knowledge remarkable income.

    In the 2017 China's Sharing Economy Development Report provided by the SIC，the turnover in China's knowledge market measures about Y61 billion, or $9 billion，which is a 205% growth compared to last year; the number of payment for knowledge users reached 300 million, accounting for half of all Chinese Internet Users.

    The investigation shows that, males are the majority of the users, accounting for nearly 60%: 25-35 year olds account for 59.3%, which mirrors the majority of Internet users, 63% of the paying users are college graduates, and 53.9% of the paying users have an income of Y3-8k,or $ 441-1176, and most are employees and junior management.

    From ancient stories to modern researches, the label（标签）attached to being left-handed is undeniable. Left-handed people, or "lefties" as they are often called, are generally believed to be good at art — Leonardo da Vinci, Picasso and Michelangelo are all left-handed.

    Our brain is divided into two parts: the left hemisphere(大脑半球)and the right hemisphere. The left hemisphere, linked to logic and analysis, is responsible for the right side of the body. The right hemisphere, linked to creativity and imagination, controls the left side of the body. So, people tend to believe lefties are controlled by the right side of the brain, and are more creative than right-handers. Some also think that lefties may not be as good as right-handers in mathematics and problem-solving skills.

    However; a recent study carried out by scientists from the University of Liverpool in the UK and the University of Milan in Italy proved this theory wrong. The study involved(涉及)more than 2,300 students in Italy aged between 6 and 17 years old. They were asked to complete several mathematical tasks of different levels. It turned out the left-handers outperformed the others when the tasks involved difficult problem-solving. This pattern was particularly clear in male adolescents. However; when it came to simple arithmetic, there was no difference between left-handers and right-handers.

    It was also discovered that those who are "severely" right-handed performed less well in all the experiments compared to "medium" right-handers and left-handers.

    "Taken together, these findings show that handedness does influence abilities to some degree," the study's authors wrote. However, "handedness is just an indirect expression of brain function," wrote psychology professor Giovanni Sala from the University of Liverpool in the UK, the lead author of the study. Sala also noted that only one third of people with a highly-developed right side of the brain are left-handed. It means that there are lots of right-handed people with a similar brain function as left-handers.
