The ninth week of SEAL(Sea, Air, Land) training is referred to as Hell Week. It is six days of no sleep, physical and mental suffering and one special day at the Mud Flats (泥沼）where you will sink into the mud.

    It is on Wednesday of Hell Week that we came down to the mud flats and spend the next 15 hours trying to survive the freezing-cold mud, the cold wind and the strong pressure from the instructors to give up.

    As the sun began to set that Wednesday evening, my training class, having broken some of the rules, was ordered into the mud. We sank into the mud until only our heads could be seen. The instructors told us we could leave the mud if only five men would give up—just five men and we could get out of the cold.

    Looking around the mud flat, it was clear that some of us were about to give up. It was still over eight hours till the sun came up--eight more hours of coldness. Our cries were so loud that it was hard to hear anything. And then, one voice began to fly through the night--one voice raised in song.

    The song sounded terrible, but it was sung with great power. One voice became two, and two became three, and before long everyone in the class was singing.

    We knew that if one man could rise above the suffering then others could as well. The instructors warned us of more time in the mud if we kept up the singing—but the singing went on and on. And somehow, the mud seemed a little warmer, the wind a little weaker and the morning not so far away.

    If I have learned anything in my time traveling the world, it is the power of hope. The power can change the world by giving people hope.

    So, if you want to change the world, start singing when you're up to your neck in mud.

    If you see a group of people dancing and singing on the street or in the railway station, you don't need to feel surprised. They are a flash mob(快闪族). Who are they Are they mobs? Don't be confused by their name. Actually, a flash mob is a group of people who gather suddenly in a public place, do something unusual for a brief period of time, and then quickly disappear.

    They are usually organized with the help of the Internet or other digital communications networks. The messages may be sent to friends, who send to more people. At a predetermined time, they gather and perform some activities such as exchanging books, coming together to look at the sky, waving their hands and yelling something at the top of their voice for 30 seconds. Then, they quickly disappear before the police can arrive Using mobile phones, the flash mob can change its place if the first one has been cancelled for any reason.

    Bill Wasik, senior editor of Hamper's Magazine, organized the first flash mob in Manhattan in May 2003 and the first successful flash mob gathered on June 3, 2003. Wasik claimed that he created the flash mob as a social experiment designed to laugh at fashion seekers and stress the cultural atmosphere of wanting to be an insider or part of "the next big thing”.

    Flash mob gatherings can sometimes shock people. Such an activity might seem amusing and magical, but it also might frighten people who are not aware of what is taking place. Undoubtedly, flash mob can serve as good political tools and have great potential, such as using flash mob to advertise a product.

    The flash mob is now becoming more and more popular. People use it to do many things. Flash mobs give people from all walks of life an opportunity to come together to create a memory.

    For years I have had no idea what I have been doing with my life. I was a 30-year-old lawyer in New York. But being a lawyer was never my dream or goal in life. I honestly wanted to be a writer. I have a great imagination and would write amazing stories in my head. But I always knew that being a writer was never possible for me because it was a better financial decision to stay a lawyer.

    Recently, I couldn't fall asleep at my usual time of 10 p. m. and when I did fall asleep I had the same dream over and over again. The dream starts with me in the ocean trying to go for a swim and I'm searching for something, but I start to drown and have no control over my body. Then a light shines through the waters and when I look up all I can see is myself in a bright white room writing a novel. Then I hear a voice say repeatedly, “Now is the time to try something new!”

    It wasn't just a dream; it was my opportunity to make something good out of my life. That afternoon, I quit my job at the law firm and I couldn't have been any happier. My life started at 30, and every day since that point I haven't stopped enjoying life. I started to write and have been on the best-sellers list for the last two months. Things have definitely turned around.

    Change is a good thing; it gives us an opportunity to take a chance. So my two favorite words I live by and so should you are “change and chance”.

    An unconventional new initiative(首创)in Canada will soon allow doctors to prescribe art to their patients—by giving them free access to a local museum. Wandering through the Montreal Museum of Fine Arts(MMFA), these patients and their loved ones will be able to feast their eyes on the peaceful collections of art.

    The initiative is the first of its kind in the world. And while you certainly can't replace a conventional treatment with a couple of paintings, the idea is for such “prescriptions” to assist a person's current treatment plan. Under the new program, members of the Francophone Association of Doctors in Canada(MFDC)will be able to hand out up to 50 prescriptions for their patients.

    These prescriptions will be available for those with a wide range of mental and physical illnesses, and each of them will allow two adults and two children to visit the museum for free.

    “By offering free admission to a safe, welcoming place, a relaxing experience, a moment of relief, and an opportunity to strengthen ties with loved ones, MMFA—MFDC Museum Prescriptions contribute to the patient's well-being and recovery, ”explains a news conference from the MMFA.

    It may look a lot like a marketing effort for the museum but there's also increasing evidence that the display of visual art, especially if it's showing nature, can have positive effects on health outcomes.

    In some ways, the benefits of looking at art appear a little similar to physical activity. A systematic review of clinical art therapy(疗法) found that visual art has significant and positive effects on depression, anxiety, mood, and self-esteem. Findings like these are slowly gaining attraction in the medical community, making artwork a higher priority(优先)in hospitals around the world.

    In the US, nearly half of all health care institutions have reported including art in health care programming, such as art therapy and the placement of visual art in hospitals. With spaces dedicated(专用的)to art therapy and also a medical consultation room, the MMFA already provides services for people with mental health issues, eating disorders, and Alzheimer's disease, just to name a few.

    If you're tired of the big city pace and noise, relax yourself by taking a day or a weekend exploring one of these four Georgia small towns：

    Senoia

    About 45 miles from Atlanta, if you want to visit the classic small town, Senoia is the best choice. Built in 1866 as a railroad town, its picture perfection has been filmed for the movies like Fried Green Tomatoes.

    Hartwell

    109 miles from Atlanta

    Named for Nancy Hart, a heroine of the Revolutionary War who served as a spy and captured a group of Tories who threatened her home, Hartwell is known as the "Best city by a Dam Site".

    Tiger

    105 miles from Atlanta in northeast Georgia, this small mountain community sits at the base of 2 856-foot Tiger Mountain, and you can drive Old U. S. 441 right through town and into the countryside any season of the year. The tiny town itself boasts the Tiger Drive-In.

Another attraction is the Tiger Mountain Winery, operating from the site of a five-generation old family farm and winner of three 2017 silver medals in the Los Angeles Wine Competition. Its tasting room is open daily.

    Tallulah Falls

    About 96 miles northeast of Atlanta

    Near the Tallulah River and named for the five falls that flow downward very fast through the gorge, Tallulah Falls had a population of just 168 at the 2010 census.

    It's a fine spot for fishing and picnicking on the town's three lakes，swimming at the Georgia Power Company's Terrora Beach. Come Saturday night in spring，summer and folk stay for live Bluegrass bands on Bluegrass Square in downtown Tallulah Falls. You can even bring your own instrument and join in.

    It was an autumn day, and 1 was standing in the kitchen, hanging my head over the counter and trying to figure out how many calories were in a bowl of homemade yogurt and fruit. And I felt annoyed.

    I was 16, and my best friend and I had gone to our first Weight Watchers meeting. It was the trend in the mid-1980s, and even though I was an athlete, like many teen girls, I didn't necessarily like what I saw in the mirror. But after a week or so of recording every meal and snack and calculating the calories, I had had enough. I went back to my routine of chowing whatever I wanted, running and skiing, and let that be that. And it's still pretty much what I do; as long as the workouts are regular and the food is whole and balanced, my body's set point hasn't varied for years.

    The weight loss trend of three decades ago−full of scales and counting calories−has fallen away. Now fasting is popular. The ways to keep fit vary: on the 5:2 diet a person eats for five days and fasts for two days each week, while the 18:6 refers 10 fasting for 18 hours and then eating within a six-hour window each day.

    In this issue, Associate Editor Mark Barna tries to understand the science behind the fasting plans. Researchers have found that animals like monkeys age more slowly after years of eating less, and in the lab in humans, they saw improvements in a number of signs that indicate risk of some hard to cure diseases. The hope for healthy weight loss isn't over yet, but at least now the calculators don't have to be out at every meal.
