According to a survey, only 4% of the people in the world are left-handed. Why? One theory centers on the two halves of the brain. For example, the left half and the right half, each of which functions differently. Medical science believes that the left half of the brain dominates over the right half. The foundation of this theory is the fact that nerves from the brain cross over at neck-level to the opposite side of the body, and nerves from the other side of the brain reciprocate (互换). The end re­sult is that the opposite sides of the body are controlled by the opposite sides of the brain.

    The dominant left half of the brain, which kindly supplies the right half of the body, theoretically makes it more skillful in read­ing, writing, speaking, and working, and makes most people right-handed. Lefties, however, whose right half of the brain dominates, work best with the left side of their bodies.

    Theory number two focuses on the asymmetrical nature of the body. Examples of the asymmetry, which flows from head to toe, are that the right side of our faces differs slightly from the left, that our legs differ in strength, or that our feet vary in size. One aspect of this asymmetry is that for most people the right hand is stronger than the left.

    There is no doubt that all exist in a “right-handed society”, which produces most basics, including scissors, doorknobs, locks, screwdrivers, automobiles, buttons on clothing, and musical instru­ments for the 96%. Left-handed people make up for the unfairness by being members of an elite (精英) society, which includes many of the greatest geniuses, including Michelangelo and Leonardo da Vinci.

    You get anxious if there's no wi-fi in the hotel or mobile phone signal up the mountain. You feel upset if your phone is getting low on power, and you secretly worry things will go wrong at work if you're not there. All these can be called “always on” stress caused by smart phone addiction.

    For some people, smart phones have liberated them from the nine-to-five work. Flexible working has given them more autonomy（自主权）in their working lives and enabled them to spend more time with their friends and families. For many others though, smart phones have become tyrants（暴君）in their pockets, never allowing them to turn them off, relax and recharge their batteries.

    Pittsburgh-based developer Kevin Holesh was worried about how much he was ignoring his family and friends in favour of his iPhone. So he developed an app — Moment — to monitor his usage. The app enables users to see how much time they're spending on the device and set up warnings if the usage limits are breached（突破）. “Moment's goal is to promote balance in your life,” his website explains. “Some time on your phone, some time off it enjoying your loving family and friends around you.”

    Dr. Christine Grant, an occupational（职业的）psychologist at Coventry University, said, “The effects of this 'always on' culture are that your mind is never resting, and you're not giving your body time to recover, so you're always stressed. And the more tired and stressed we get, the more mistakes we make. Physical and mental health can suffer.”

    And as the number of connected smart phones is increasing, so is the amount of data. This is leading to a sort of decision paralysis（瘫痪）and is creating more stress in the workplace because people have to receive a broader range of data and communications which are often difficult to manage. “It actually makes it more difficult to make decisions and many do less because they're controlled by it all and fell they can never escape the office,” said Dr. Christine Grant.

    If you love to read, and if you love social networking, you should check out Goodreads. Goodreads allows you to write reviews（评论）for everything you've ever read. You can see and comment on your friends' reading progress, as well as create or find a book club group page in your area.

    Goodreads is simple to use. When you sign up here for an account（帐户）, you will be able to find your friends by their email addresses or other accounts. Once you have some friends, every time you log in（登录）, you will see a timeline of their updates. You can see when they've added a book to a list, or when they've finished or reviewed a book. As soon as you have an account, you can also start looking for books you've read or that you want to read. Once you finish reading a book, you can go to the book page and review it.

    Finding your next book has never been easier. Now, not only can you search for books you know you want to read and add them to your “to read” list, but you can also easily see what your friends have recently read.

    If you are looking for a book club that meets in your area, you can search for that on Goodreads, too. Similarly, if you want to create your own book club, you can do that easily: just start a new group on Goodreads and update the page to show what books you're reading.

    Pakistan should be everyone's tourist destination for 2018, but what if you already live there? Then perhaps you should consider visiting these five must-visit places for this year.

    Lake Saiful Muluk

    At an altitude of 3, 224m, surrounded by snowy mountains, the lake rewards those that make the three-hour uphill walk from Naran. You will find the pathway just above the free market, but the best choice is to get a jeep and share the costs with some other tourists; expect to pay about 700 rupees, worth it to view this natural beauty.

    Deosai National Park

    As another high point in Pakistan, it has an average altitude of 4,114m－the Deosai Plains are one of the highest plateaus (高原) in the world. If you make it to the park, you expect to find rich plants and wild animals. The breathtaking scenery on show at the plains is enough to make 2018 a memorable year.

    Naltar Valley

    Accessible via a 2.5-hour drive from Gilgit, well worth visiting. Covered with pine trees and other plants, it has a dreamlike feel about it. Various colors all year around make you fall in love.

    Shangrila Resort

    Right in the north of Pakistan in the central valley of Gilgit Baltistan. Locals call this a paradise (乐园), and that's what it feels like. No visit is complete without checking out the restaurant which is built in the structure of an aircraft.

    Rama Meadow (牧场)

    Doesn't feel like Pakistan at all, more like somewhere in Minnesota. Watch the sheep and cows feeding while clear water flows in streams from high in the mountains. Against Chongra's ice-covered peak, this little meadow is a piece of art.

    Many children are interested in dinosaurs (恐龙). If you have a child who loves dinosaurs, then here is some good news for you. There is an exhibition of dinosaurs at the Philip J. Currie Dinosaur Museum in Wembley, Albert A. You can plan a family road trip there. Give your child a surprise and you'll enjoy your time there as a family.

    Sitting just 19 kilometers west of Grande Prairie, the Philip J. Currie Dinosaur Museum was opened in 2015 and has collections that include fossils（化石）of sea animals, art works from different dinosaurs, a large family theater, as well as an outdoor discovery fossil walk, a large outdoor playground and the onsite Dine-O-Saur restaurant. Experience the dinosaurs' world like never before as you watch dinosaurs coming alive in movies. Learn about how these animals lived and breathed.

    You can check out Dinosaurs Unearthed and all of the other exciting exhibitions at the Philip J. Currie Dinosaur Museum on the following days/ time periods:

    Imagine jet-setting from Tokyo to Paris, enjoying first-class travel, a four-course dinner and a city tour－all without leaving the ground. This is the future of air travel according to Japanese company First Airlines, which has used the power of virtual reality to create dream vacations.

    Passengers avoid the costly airport transfer, the baggage fees or busy airport terminal（航站楼）－and instead enjoy the privileges of business or first-class travel and an expensive tour of Paris－all while remaining motionless in Tokyo. As well as Paris, First Airlines also offers the virtual destinations of New York, Rome and Hawaii.

    After boarding, guests can settle down for the two-hour flight on their advanced Airbus seat－surrounded by decoration that is modeled on the inside of an aircraft, for maximum realism. There is flight service and VR, foods, music for every destination. Passengers will be served a delicious meal by air stewards, alongside drinks and other desserts. The menu depends on the destination of choice－Manhattan clam chowder and cheesecake for New York and salmon tartar and onion soup for Paris. After landing at the destination, guests can enjoy a 360-degree tour of the destination－all thanks to projection（投影）mapping and video.

    It makes for a supposedly stress-free vacation, perfect for those whose ability to travel abroad is limited by cost or health. Virtual reality is becoming increasingly present everywhere at all times in the world of travel－allowing travelers to appreciate the wonders of the world, all without leaving their house.

    At just 4,980 yen（$ 46）for business class and 5,980 yen（$ 56）for first class－these two- hour flights are far more affordable than their real-life flights. Tokyo citizens eager to experience First Airlines can book a trip on the website, with reservations currently being taken until May 2018.
