If you've ever owned a chimney, you know that it can get pretty dirty. There's a whole lot of soot(烟灰) that gets stuck on the inside. That stuff has to get cleaned, or you could have a serious fire risk. While nowadays we have easier ways of doing this dirty job, in the way back days somebody used to climb up the chimney and clean all that soot. And the thing is, not just anybody could do it.

    You had to be really small to fit up in the chimney, so they used to give the task to kids – some as young as four or five years old. They worked for their boss known as a master-sweep. They were often covered in soot, and were very likely to get burned. They often developed what became known as soot wart, a form of cancer.

    Are your unfairness bells ringing? William Blake's certainly were. The physical dangers and widespread unfairness of the chimney-sweeping job really stuck in his throat, so much so that he wrote not one, but two poems called “The Chimney Sweeper”.

    The first poem (the one we're discussing here)was published in 1789 in a book called Songs of Innocence. These little poems took children and the joys of childhood innocence as their subject. As you've probably guessed by now, many of the poems in Songs of Innocence, like “The Chimney Sweeper”, are about the ways in which childhood innocence is destroyed by unkind old adults. For Blake, innocence is, in many ways, a total joke. It doesn't exist, because it's always taken away by the realistic world – chimney-sweeping, death, poverty, etc.

    What does a five-year-old chimney sweeper in 18th-century England have to do with you? More than you might think. It is reported that 150 million kids are in child labor in developing countries. Many of them work long hours and face dangerous health risks. Like Blake's chimney sweeper, these kids are not even given a chance at innocence because experience keeps getting in the way.

    “This way, everyone.” said the young Bahamian as he led the way to the boat. As the boat moved over the waves, I thought back eleven years to my first island visit via a cruise ship. As we landed, I noticed a sign advertising swimming with dolphins. I looked at my mother; she knew exactly what I wanted, but I was too young. “Maybe some other time,” she said. I think everyone knows that those four words usually translate to never. It made me, a little boy, depressed for many days. From that day on, it was my dream to swim with those gentle creatures.

    Now, after 15 minutes of travelling, we reached the Sanctuary Bay. As we arrived, I saw the gray creatures showing off their unique talent before my eyes. We were led off the boat, past a back building. Our guide told us we would have the pleasure of spending the next 90 minutes with Kaholo, a young male, and Robola, the largest female, who is quite famous for having played the lead in the film Zeus and Roxanne.

    My father and I were joined by four others and followed the man once more. He told us to jump into the water while he let the dolphins into that part of the bay. For the first 20 minutes, we could go anywhere and touch the dolphins as they swam by.

    Kaholo and Robola must have known I was their biggest fan because they swam towards me as if I had had fish. After the introductory period, they jumped over our heads. I got a hug and kiss from Robola, and also learned how to have Kaholo talk to me.

    This was by far the most magical experience of my life. Next time your parents say “Maybe some other day”, have faith in them. Your dreams are important to them too, and they will do whatever they can to make it possible, because dreams can come true.

    There are billions of people on this planet, and many of us love to eat meat. Can the demand be filled in a sustainable(可持续的) and affordable way? A bunch of businessmen are not only optimistic but are working to make this happen sooner than you may think.

    The environmental effects caused by meat consumption (食用)—waste, animal treatment, health problems and even the greenhouse gas effects that are potentially caused by methane gas produced by cows—have given rise to a number of startups(新兴公司)looking to develop meats in different ways.

    For example, San Francisco-based Memphis Meats is developing cell-based meats in its labs without requiring any animals. Israel's Future Meat Technologies is doing the same by producing fat and muscle cells that are being tested by chefs in Jerusalem. All of these companies use special processes to harvest cells from animals and grow them in a lab.

    But don't worry if you're not a meat lover. Startups such as Jet Eat, which is also based in Israel, are working on food products grown in labs that are plant-based and replicate (复制) meats using natural elements while still keeping flavor, consistency and the "overall sensory experience", according to a report on NoCamels. Jet Eat, which was founded in early 2018, aims to 3D-print their lab-grown products by 2020.

    As you can imagine, there are plenty of barriers facing the industry. Educating the public is a big one. Another controversial issue is the labeling of the products. Recently both the USDA and the Food and Drug Administration (FDA) announced that they will begin jointly controlling the new "cell-based meat" category.

    Many of us have concerns about the challenges facing future generations as our global population increases and the earth's natural resources decreases. The good news is that there are plenty of businessmen around the world—like those producing lab-grown meats—who are working to solve some of these problems and make a little money in the process. Nothing wrong with that.

    If your life were a book and you were the author, how would you want your story to go? That's the question that changed my life forever.

    At the age of 19, I became a massage therapist(治疗师). For the first time in my life, I felt free, independent and completely in control of my life. That is, until my life took a detour. I was diagnosed with bacterial meningitis. Over the course of two months, I lost my spleen(脾), my kidneys, and both of my legs below the knees.

    One day, I went home. I crawled into bed and this is what my life looked like for the next few months me passed out, escaping from reality, with my legs resting by my side. I was completely physically and emotionally broken. But I knew that in order to move forward, I had to let go of the old Amy and learn to embrace the new Amy. And that is when I began to realize that I didn't have to be small any more. I could be as tall as I wanted or as short as I wanted depending on whom I was dating. And if I snowboard again, my feet aren't going to get cold. And the best of all, I thought, I can make my feet the size of all the shoes that are on the sales shelf. And I did!

    I started snowboarding. Then I went back to work. And then I co-founded a non-profit organization for physical disabilities so that they could get involved in action sports. And just this past February, I won two World Cup gold medals, making me the highest-ranked adaptive female snowboarder in the world.

    Eleven years ago, when I lost my legs, I had no idea what to expect. But if you ask me today, if I would ever want to change my situation, I would have to say no, because my legs haven't disabled me. They've forced me to rely on my imagination and to believe in possibilities, and that's why I believe that our imaginations can be used as tools for breaking through borders, because in our minds, we can do anything and we can be anything. It's belief in those dreams and facing our fears directly that allow us to live our lives beyond our limits.

Is life a story or a game? Answers may vary from one to another. Over the course of life, we find things to love and commit to —a job, a partner or a community. At times, we struggle to learn from our misfortunes to grow in wisdom, kindness and grace.

Will Storr, a writer whose work I admire, says this story version of life is a misunderstanding. In his book The Status Game, he argues that human beings are deeply driven by status. Rather than about being liked or accepted, he writes, it's about being better than others. "When people are obedient to us, offer respect, admiration or praise, that's status. It feels good."

Life is a series of games, he adds. There's the high school game of competing to be the popular kid. The lawyer game to make partner. The finance game to make the most money. The academic game for fame. The sports game to show that our team is the best. Even when we are trying to do good, Storr claims, we're playing the "virtue game" to show we are morally superior to others.

I think Storr is in danger of becoming one of those guys who ignore the noble desires of the human heart and the caring element in every friendship and family. The status-mad world that Storr describes is so loveless. In fact, gaming as a way of life is immature. Maturity means rising above the shallow desire —for status —that doesn't really nourish us. It's about cultivating the higher desires: the love of truth and learning; the inner pleasure the craftsman gets in his work, which is not about popularity, and the desire for a good and meaningful life that inspires people to practise daily acts of generosity.

How do people gradually learn to cultivate these higher motivations? To answer that, I'd have to tell you a story.

It was 1504,and Columbus was making another trip to the New World.Columbus and his men needed fresh water and food after three months at sea.They saw an island and went to the shore.On the island there were unfriendly Indians who refused to give food and water to them.Columbus' men were afraid of the Indians,but he had a clever plan.He used gesture(手势) language to tell the Indians about his mysterious (神秘的) power to turn off the light in the sky.He knew about a lunar eclipse (月食) the next night because the information was in his almanac (天文历书).Columbus told the Indians,"Tomorrow night I'll turn off the light in the sky." But they didn't believe him.When the eclipse began the next night,the Indians became very frightened.They begged Columbus to turn on the light again,and they quickly gave him all the food and water he wanted.Immediately Columbus and his men hurried back to the ship and sailed away in the moonless night.
