The science fiction type of entertainment is considered by mot to be fathered by Jules Verne (A Journey to the Center of the Earth and Twenty Thousand Leagues Under the Sea) and H. G. Wells (The Time Machine and The War of the Worlds). Sei-Fi, as it is commonly shortened, is a fictional story in which science and technology have a significant influence on the characters and plot. Many such works are guesswork about what the future holds and how scientific findings and technological advances will shape humankind.

    Writing in the late 1800s, Jules Verne was remarkably successful in his 10 guesses about future technologies of air conditioning, automobiles, the Internet, television, and underwater, air, and space travel. Unbelievably, of all places from which to choose, Jules Verne guessed Tampa, Florida, USA as the launching site of the first project to the Moon, which was only 200 kilometers away from the actual 1969 location at Cape Canaveral, Florida.

    One of the best-known science fiction books is Nineteen Eighty-Four by George Orwell. Published in 1949, it was not meant as a prediction, but as a warning: Orwell was describing what he saw as the outcome of the ideas, trends, and emerging technologies of his time. Many invented terms from this novel have become common in everyday use, such as “big brother” and “doublethink”. Even the author's name has been made into an adjective—Orwellian—and has become a warning descriptor for situations where privacy is lost and the individual has no power and is completely controlled by the government. Nineteen Eighty-Four was translated into sixty-five languages within five years of its publication, setting a record that still stands.

    What helps bring science fiction into being is usually a new discovery or innovation. The author creates an analysis of the potential influence and consequences and then wraps it in a pleasant story. For example, the beginning of space exploration was followed a few years later by the Star Trek television program and movie series. The science fiction author's self-determined role is search the world of future possibilities upon the road which we are traveling.

    There is a story about a man who lost his legs and left arm in an accident. After the accident, only a finger and thumb on his right hand remained.

    He was a brilliant, creative, and educated man. He had gained a lot of experience while traveling around the world, so he became very depressed after his accident. He was afraid that he would spend the rest of his life suffering and would no longer be able to spend his life in a meaningful way. Then, he realized that he still had partial function of his right hand and could still write even though it was very difficult. An idea occurred to him. “Why not write to other people who need encouragement?”

    He wrote to the prison ministry about sending letters to the prisoners. The prison minister replied, “Writing to the prisoners is acceptable, but your letters will not be answered.”

    Filled with excitement, the man knew he could write his letters. He began sending one-way messages of God's love, hope, strength, and encouragement. He wrote twice a week, testing his strength and ability to the limit. He poured his heart and soul into his words and shared his experience, sense of humor, optimism, and faith.

    It was difficult to write those letters, especially without hope of a reply. One day he received a letter from the prison ministry. It was a short note from the officer who monitored and checked the prison mail.

    The letter said, “Please write on the best paper you can afford. Your letters are passed from cell (囚房) to cell until they literally (逐字地) fall to pieces!”

    No matter what circumstances life may present, we all have unique experiences, abilities, and God-given talents. We can discover ways to reach others who desperately need messages of encouragement and strength.

    The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. As we know, we're sitting while we're eating; we sit in the car and we sit while we watch TV. And many of us sit for many hours at work.

    New research shows that sitting less than three hours a day might extend your life by two years. Peter Katzmarzyk, a scientist at the University of Louisiana in the southern United States, says that sitting is ubiquitous in our lives, meaning it is something we do all the time, everywhere.

    However, Mr. Katzmarzyk says that does not mean you can sit for the rest of your waking hours. He also says you may exercise often, "We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that."

    Mr. Katzmarzyk and his colleagues are part of a new generation of researchers studying how sitting all day affects length of life. "Studies that have assessed the relationship between sitting and mortality (死亡率) or television viewing and mortality are very rare. There's only been a few of them, actually five or six now, in the last four or five years." They found that cutting television time to less than two hours a day could add one point four years to life.

    Luckily, change is already coming to some offices, especially in the design of desks. A "standing desk" lets people stand while they work. Another new design is called the "treadmill desk." A treadmill is an exercise machine that lets you walk in one place. Even some U.S. schools are beginning to experiment with desks that are part bicycle to keep children moving. That's one of the strategies that many companies are using now.

    Mr. Katzmarzyk also says studying this problem has inspired his team to make a few changes in their own lives.

    Devon Gallagher, a college graduate from Philadelphia, wants the world to know exactly here she's been during her worldwide vacation in a special way.

    The traveler, who was born with a bone disease, had her right leg amputated(k)at the age of four. Although the amputation caused setbacks for Gallagher early on, she now sees it as nothing short of inspiration for living her best life.

    To spread that message, Gallagher has taken to social media, where she shares photos of her travels across the globe, but instead of simply using a geo-tag, she writes her location across her artificial leg before taking a picture.

    Now she has been taking pictures across the Continent, which show her cycling over the canal in Amsterdam relaxing on a wall overlooking the city of Barcelona, posing with a waffle in Brussels, taking in the spectacular Parthenon temple in Athens and enjoying a river cruise in Budapest, all with the well-known locations written on her artificial leg “I get a new leg every two years and I can choose the design on it. One day I had a sudden thought to get a chalk-board, "Gallagher said. "My mum and grand-mother weren't too keen on the idea, but my friends thought it was great and told me to go for it, so I did.”

    Gallagher said people often stare when she's writing on her leg, but once she shares the photos she receives only positive feedback. "My leg hasn't stopped me from doing anything I've wanted to do," she said. "I don't know if it's my determination to prove to myself that I can do it, but regardless, I've been able to keep up with my peers and lead a pretty great life, Gallagher shows us that you should never let anything stand in the way of your dreams. And if life gives you an artificial leg, make art

    Whenever something looks interesting or beautiful, there's a natural impulse(冲动) to want to own and preserve it — which means, in this day and age, that we're likely to reach for our phones to take a picture.

    Though this would seem to be an ideal solution, there are two big problems associated with taking pictures. Firstly, we're likely to be so busy taking the pictures that we forget to look at the world whose beauty and interest drove us to take a photograph in the first place. And secondly, because we feel the pictures are safely stored on our phones, we never get around to looking at them, so sure are we that we'll get around to it one day.

    These problems were noticed right at the beginning of the history of photography, when the average camera was the size of a grandfather clock. The first person to notice them was the English art critic, John Ruskin. He was a traveler who realized that most tourists make a boring job of noticing or remembering the beautiful things they see. He argued that humans have a natural tendency to respond to beauty and wish to have it, but that there are better and worse expressions of this desire. At worst, we get into buying souvenirs or taking photographs. But, in Ruskin's eyes, there's one thing we should do and that is attempt to draw the interesting things we see, no matter whether we have any talent for doing so.

    Ruskin was very upset by how seldom people notice details. He strongly disliked the travelers who prided themselves on covering Europe in a week by train. "If he be truly a man, no harm to go slow; for his glory is not at all in going, but in being."

While conquering the world's swimming pools in the late 1990s and the 2000s, Amanda Beard had already included breathing exercises in her training. Several years after the end of her athletic career, she discovered walking meditation. Today the seven-time US Olympic medalist practices walking meditation in nature, around the house, or while walking the dog. It's a daily practice with the focused mindfulness of meditation that contributes positively to every aspect of her life, she says. 

You don't need equipment or a designated space to start. The idea of a walking meditation is to pay attention to the way your body feels, noticing things like the sky, trees, tuning into all of your senses. This means you can meditate "on the go" in the countryside, in the city, in your backyard, and virtually anywhere. A simple, 10-minute walking meditation for beginners requires that you just start at ease. Consider what you hear, smell and see. Think about how your feet touch the ground. Fully focus on these feelings. 

A report in Health Promotion Perspectives also found that walking meditation can improve your balance, adjust your heart rate, boost your mental focus, and help you battle anxiety and depression. "The benefits of meditation are many," says Dr. Schramm, a board-certified family physician and meditation teacher. "When we do this over and over again, we train the brain to focus on only one thing at a time and this increases both our blood flow and actual neuronal (神经元) changes within our brains. "

"The magic of meditation is to be able to help you connect with yourself; meditation shouldn't feel a certain way," says Tara Stiles, a yoga and wellness expert. It's a common mistake in meditation: People fear a wandering mind. "A wandering mind is completely normal," Stiles says. "Even experienced meditators aren't sitting there never having a thought, but when they have the thought they choose to guide themselves back to their breath instead of getting frustrated.
