Stress is a word we hear a lot these days. People have stressful jobs; they feel stressed while studying for exams; even family life can be stressful. Stress can cause headaches and lack of sleep arid research has shown that it is one of the main causes of heart disease. None of us can completely avoid stress. Everyone experiences it.

    In ancient times, stress served a different purpose. It kept us alive. When a caveman was walking along and was suddenly faced with a lion, the stress he experienced would make him run away faster than he could usually run. Stress is the state our bodies experience when we need to react to difficult or dangerous situations. While stress saved us back then, and it is still very helpful in difficult situations, we need a break from stress every now and again.

    Luckily, there are ways to relax and deal with stress and it seems that music might be our number one cure. A recent worldwide study showed that listening to music is what most people do to relax and reduce stress. The study was based on interviews with 1,000 people in 30 countries and 56% said that listening to music was the best way to relax. Watching TV, at 53%, was the next most popular way of reducing stress followed by taking a shower or bath at 49%. It is not really surprising that listening to music is such a popular way of relaxing. It is cheap and widely available on radio, TV and the Internet.

    Of course, musical tastes differ from person to person. Sam might love listening to loud heavy metal music to relax after a hard day's work, but his neighbour - a fan of Mozart - might find hearing his music extremely stressful. “Sam needs an iPod”, you- might be thinking and you are probably right. Mobile music players can provide music privately whenever and wherever it is needed; we could even call them the stress fighters of the 21st century. So the next time you fed stressed, take a deep breath, put on your earphones and ... relax.

    Who's in control of your life? Who's pulling your strings? For the majority of us, it's other people-society, colleagues, friends, family or our community. We learned this way of operating when we were very young, of course. We were brainwashed. We discovered that feeling important and feeling accepted was a nice experience and so we learned to do everything we could to make other people like us. As Oscar Wilde puts it," Most people are other people. Their thoughts are someone else's opinions, their lives a mimicry, their passions a quotation."

    So when people tell us how wonderful we are, it makes us feel good. We long for this good feeling like a drug-we are addicted to it and seek it out wherever we can. Therefore, we are so eager for the approval of others that we live unhappy and limited lives, failing to do the things we really want to. Just as drug addicts and alcoholics live worsened lives to keep getting their fix(成瘾物)we worsen our own existence to get our own constant fix of approval.

    But, just as with any drug, there is a price to pay. The price of the approval drug is freedom-the freedom to be ourselves. The truth is that we cannot control what other people think. People have their own agenda, and they come with their own baggage and, in the end, they're more interested in themselves than in you. Furthermore, if we try to live by the opinions of others, we will build our life on sinking sand. Everyone has a different way of thinking, and people change their opinions all the time. The person who tries to please everyone will only end up getting exhausted (tired) and probably pleasing no one in the process.

    So how can we take back control? I think there's only one way-make a conscious decision to stop caring what other people think. We should guide ourselves by means of a set of values- not values imposed from the outside by others, but innate values which come from within. If we are driven by these values and not by the changing opinions and value systems of others, we will live a more authentic, effective, purposeful and happy life.

    Not all of George H.W. Bush's extended family members were invited to his Washington D.C. memorial service.

    Nearly a week after many paid their respects at the Washington National Cathedral, Sharon Bush, who was married to the 41st president's son Neil from 1980 to 2003, told Page Six that she was allegedly unable to attend the funeral after she was told by her ex-husband's secretary that there were not enough seats.

    "I was going to take the train down. I wanted to pay my respects. But I paid my respects by raising three wonderful children during a 23-year marriage," Sharon told the Outlet.

    Neil and Sharon share three children: son Pierce and daughters Ashley and Lauren Bush Lauren, who gave a reading at the funeral, where the father of three attended with his second wife Maria Andrews, whom he wed in 2004.

    While the D.C. memorial service was taking place, Sharon recalled having lunch with Lady Gaga's mother Cynthia Germanotta and publishing heiress Anne Hearst.

    Though she was snubbed from the funeral, Sharon shared photos on Instagram to honor her former father-in-law. "My girls Lauren and Ashley read scriptures at their grandfather's funeral. I feel so proud of them. May he RIP." The mother of three captioned a photo of Lauren and Ashley.

    "May he RIP," Sharon also posted on Instagram, speaking of their children's upbringing. Sharon credited herself for raising them to be charitable and public servants. "I taught them everything they know about 'points of light' by taking them to soup kitchens and homeless shelters from the time they were 4 years old. I didn't want them spoiled," she said, referencing the public service nonprofit — Points of Light, for which her ex-husband serves as chairman of the board of directors. "I did this. Neil was never around. He was always traveling," Sharon added.

    Many people have long dreamed of being able to fly around as simply as riding a bicycle.

    Yet the safety and strength of a flying bike was always a big problem. Over the past 10 years' developments in technology have moved the dream of personal flying vehicle closer to reality. Now, two groups of inventors say such vehicles may be available very soon.

    Grant Stapleton from Malloy Aeronautics says the Hoverbike, which is able to get in and out of small spaces very quickly, will be a truly personal flying vehicle." It can be moved across continents very quickly because it can be folded and packed," he adds.

    Mr. Stapleton says safety was the company's main concern when developing the Hoverbike, He says the designers solved the safety issue by using overlapping rotors (折叠旋翼)to power the vehicle. The company is testing both a one-third size model and a full-size prototype (原型))of the Hoverbike.

    Inventors say their Hovebike will most likely be used first by the police and emergency rescue teams.

    In New Zealand, the Martin Aircraft Company is also testing a full-size prototype of its personal flying bike, called Jetpack. It can fly for more than 30 minutes, up to 1,000 meters high and reach a speed of 74 kilometers per hour.

    Peter Coker is the CEO of Martin Aircraft Company. He said Jetpack" is built around safety from the start" In his words, reliability is the most important part of it. We have safety built into the actual structure itself very similar to a Formula One racing car."

    Jetpack uses a gasoline-powered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute (降落伞)that can be used should there be an emergency.

    "It opens at a very low altitude and actually saves both the aircraft and the pilot in an emergency," he adds.

China's Tianwen 1 Mars probe (探测器) conducted its fourth orbital correction on Friday evening, as the spacecraft makes ready for its arrival in orbit around Feb. 10, according to the China National Space Administration.

The name comes from the long poem Tianwen, meaning Heavenly Questions or Questions to Heaven, written by Qu Yuan, one of the greatest poets of ancient China. In Tianwen, this name conveys the Chinese nation's steady effort in pursuing truth and culture of exploring nature and the universe. CNSA also unveiled (发布) the logo of China's planetary exploration missions, featuring the letter C, signifying China, international cooperation and capacity of entering space.

Tianwen I has flown for 197 days and more than 465 million kilometers on its journey to the planet. It is now around 184 million km from Earth and I. I million km from Mars. Depending on the two planets' orbits, Mars is between 55 and 400 million km from Earth. Mars probe Tianwen I is seen in its first selfies in space on Oct. 1, 2020. The administration also published a black-and-white picture of Mars taken by Tianwen I, the first snapshot (抓拍的照片) from the Chinese craft.

Tianwen I, the country's first independent Mars mission, was launched by a Long March 5 heavy-lift carrier rocket on July 23 from the Wenchang Space Launch Center in Hainan province, kicking off the nation's planetary exploration program.

A successful landing would make China only the second nation to place a spacecraft on the Martian planet. China would also be the first to successfully orbit, land and deploy (部署) a vehicle in the same mission. According to experts, searching for signs of life on Mars will be the first and foremost scientific goal. China is open and inclusive in the development of its space technology not least because it believes that the exploration of outer space should help build a community with a shared future for mankind.
