There have always been a lot of commonly believed but false ideas about being fat and doing exercise. Some people believe that they can't help putting on weight as they get older, while others hold that if they stop exercising, their muscles will turn into fat. Here are some more myths:

I'll never lose weight — I come from a fat family

    Wrong! While we can't change the body type we are born with, we can't blame our genes for making us fat. There's plenty of evidence that fatness runs in families, and the main reason is that they share the same habits of eating too much and exercise too little.

    I am fat because I burn calories slowly

    Wrong! Fatness is not caused by a slow metabolism（新陈代谢）. If fact, although fat people consume more energy that slim people, they also fail to realize how much they eat! Keeping a diary can help you work out your daily food intake more accurately.

    Exercise is boring

    Wrong! Anything will become boring if you do it repetitively. The key is to develop a balanced and varied program that's fun as well as progressive. If you enjoy a Sunday walk, take a different route. If you do Yoga, try a tai chi class. If you like swimming, set yourself a distance or time challenge.

    No pain, no gain

    Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something's wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but this your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If you don't, rest and seek medical advice.

    Oil is essential for modern life. About 64 percent of the world's oil is located in the Middle East, but the heaviest consumers of oil are Europe, America, and Japan. The problem lies in getting the oil from the countries that produce it to the countries that consume it. This is mainly done using oil tankers. Usually the oil is shipped safely and with no problems, but occasionally there is a disaster.

    Every year millions of tons of oil are spilled into the ocean. Although this is only a small percentage of the total amount shipped around the world each year, this spilled oil can have terrible effects on ocean life, including the coastlines where the oil washes up onto shore.

    One of the worst oil spills in history occurred along the Alaskan coastline in 1989, when the Exxon Valdez tanker ran aground off the coast of Alaska, spilling 42 million liters of oil. Although it wasn't the largest oil spill, the disaster was terrible because it occurred in such a sensitive natural area. In this spill, the tanker's captain, who was tired from overwork and drinking alcohol, had gone to take a rest. He gave control of the ship to another sailor, who was unfamiliar with the route. The ship ran onto Bligh Reef. Damaged by the reef, the ship leaked oil out into the ocean. More than 1,600 kilometers of coastline were affected by the oil spill. Many birds and otters died as a result of the oil covering their skin, and many other sea creatures and the animals that fed on them were also severely affected.

    A woman was sitting by herself in a movie theatre. The movie she was about to set was a musical version(版本)of a very successful book that had sold a million copies that year.

    As the woman was waiting for the movie to begin, she noticed that the theatre was very crowded but the two seats next to her were empty.

    Suddenly a large man carrying a big fur coat walked down the aisle(走廊) and sat down, placing the fur coat on the seat next to her.

    When the lights went out, the fur coat bean to move, and the woman realized it was not a coat but a large furry dog. He was sitting up in the seat, watching the movie screen with great interest. As soon as the movie started, the dog began to nod his head and beat his paws (爪) in perfect time to the music.

    When the movie was over, the woman turned to the man and said, “Excuse me, sir, but I've never seen Such a well-behaved dog in a movie theatre before. Does he go to the movies often?”

    “Oh, yes,” replied the man.

    “And he seemed to enjoy everything so much,” she said, “It was just amazing!”

    “As a matter of fact, it surprised me too.” said the man. “He hated the books！”

    An international group of coffee experts has considered Ethiopia's coffee as the best in the world. Coffee is a top export of the country. But at home, it is seen as national pride. Ethiopians feel good about their coffee, and enjoying a drink with friends is a long tradition.

    International coffee experts travel the world to find the best coffee. They keep returning to Ethiopia. Some people say the climate produces quality beans. Morton Wenner is a coffee importer. He said, “Ethiopia has different ancient types of coffee. They are planted in places with perfect soil, perfect altitude, and climates that are really suitable for coffee processing, such as drying and things like that.”

    Finding the best quality beans is often an issue of taste. The process is known as cupping — tasting and comparing coffee from different roasted beans, grading and then pricing them.

    But before international experts come to taste, coffee beans are studied in small coffee laboratories. Helen Assefa, a lab technician, describes the process, “When the coffee comes to the lab, we assess its quality first by recording the details. Then we weigh the wetness level and screen the beans for analysis. After that we polish the coffee beans and taste the samples. At the end we check for imperfect beans.”

    Ethiopia is making big profits on its coffee reputation by exporting coffee to more than 120 countries. The country has an export income of more than $840 million a year. But not all the best coffee leaves Ethiopia. Forty percent of the coffee grown in the country stays there. It remains an important part of everyday life at work, at home and at ceremonies just to celebrate that special cup.

The public footpath laid barely 20 meters from where I stood, promising a walk along the river, passing fields and through woodland, well away from any road. Yet there was something in my way—the River Thames.

I checked my map to see how to reach the path, but there was no other footpath that would lead me to the island on which it sat. It was only accessible by boat—kid's dream. Similar to a talent show, some performances are educational but mostly, they just make you laugh. Talent is irrelevant, and audience engagement through call and response is essential.

Away from phones and peers back home, social norms fade and space for self-exploration forms. Shy kids come out of their shells, and cool kids let_their_guard_down. They get to open up this door to a part of themselves that they wouldn't have felt safe to reveal at school or at home.

It's been a decade since my last performance as a camp counselor, and I never thought of skits from a skill-building perspective. But I now realize this rich camp tradition left a great impression on me. Through camp skits, I developed my sense of humor, built confidence in front of a crowd, and learned how to accept others for their quirks（怪癖）.

Maybe we can make our schools or communities more like summer camps by bringing the silliness of skits into our families and classrooms to reconnect with ourselves and each other. The next time you're sitting around a campfire with friends and family, give it a try. Embrace the discomfort and invite your loved ones to join in on the improvising（即兴创作）. And remember: the more funny noises and childlike humor, the better.
