    Valerie Stull begins her mornings with a breakfast shake, into which she puts peanut butter, cocoa powder, banana, and milk. The last thing to go in is a powder made from insects.

    Stull works at the Global Health Institute. She's in a group of researchers who study the impacts of eating insects. There's a name for dining on insects: entomophagy.

    About two billion people regularly eat insects. That's almost one in every four. Most North Americans and Europeans tend to find the idea of entomophagy disgusting. Yet even in their parts of the world, insect eating is starting to catch on. That's especially true when the insects are eaten, as Stull's are, in a form that doesn't show their eyes, wings and feet.

    "Some scientists view eatable insects as mini-livestock(小型牲畜)." Compared to raising cattle and more traditional livestock, insects need far less natural resources such as land and water. Insects also are nutritious. They're packed with protein, vitamins and minerals. Plus, their outer shells contain chitin—a source of fiber.

    Stull wondered if chitin and other fibers in insects might offer health benefits similar to other fibers found in a typical American diet. To find out, she teamed up with Tiffany Weir, who's a scientist at Colorado State University in Fort Collins. Breakfasts enriched with insects changed the amount of different bacteria in the gut(肠道),the two now report. And those changes were in a direction that should improve a diner's health.

    These findings suggest that insects work as prebiotics(益生元).Scientists think probiotics, which fuel the growth of helpful gut bacteria (肠道细菌),have longer and larger benefits than probiotics(益生菌)do. Probiotics exist in your gut, and you can also add them to your diet. But, Stull explains, "When you have probiotics, you're taking in a whole bunch of beneficial bacteria. But if you don't feed those beneficial bacteria, they're not going to stick around very long."

    It's possible that insects offer larger benefits to people who eat them regularly. In a future study, Stull's team would like to test that idea.

    Maybe you are aware that the latest job markets news isn't promising: Unemployment is still more than 9 percent, and new job growth has fallen close to zero, which is bad for economy, of course. And it may be especially discouraging if you happen to be looking for a job or hoping to change careers right now. But it actually shouldn't matter to you nearly as much as you think.

    That's because job growth numbers don't matter to job hunters as much as job turnover data. After all, existing jobs open up every day due to promotions, resignations, terminations, and retirements. In both good times and bad, turnover creates more openings than economic growth does. Even in June of 2007, when the economy was still falling along, job growth was only 132,000, while turnover was 4.7 million!

    And as it turns out, even today — with job growth near zero — over 4 million job hunters are being hired every month.

    I don't mean to imply that overall job growth doesn't have an impact on one's ability to land a job. It's true that if total employment were higher, it would mean more jobs for all of us to choose from. And it's true that there are currently more people applying for each available job opening, regardless of whether it's a new one or not.

    But what often distinguishes those who land jobs from those who don't is their ability to stay motivated. They're willing to do the hard work of identifying their valuable skills; be creative about where and how to look; learn how to present themselves to potential employers; and keep going, even after repeated rejections. The Bureau of Labor Statistics data showed that 2.7 million people who wanted and were available for work hadn't looked for a job within the last four weeks and were no longer even classified as unemployed.

    So don't let the headlines fool you into giving up. Four million people get hired every month in the U.S. You can be one of them.

    We now think that chocolate is sweet, but once it was bitter. We think of it as a candy, but once it was a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack. Sometimes it's an ingredient(构成部分)in the main course of a meal. Mexicans make a hot chocolate sauce called Mole and pour it over chicken. The Mexicans also eat chocolate with spices like chili peppers.

    Chocolate is a product of the tropical cacao tree. The beans taste so bitter that even the monkeys say "Ugh!" and run away. Workers must first dry and then roast the beans. This removes the bitter taste.

    The word "chocolate" comes from a Mayan word. The Mayas were an ancient people who once lived in Mexico. They valued the cacao tree. Some used the beans for money, while others crushed them to make a drink.

    When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao, too. Because the drink was strong and bitter, they thought it was a medicine. No one had the idea of adding sugar. The Spaniards took some beans back to Europe and opened cafes. Wealthy people drank cacao and said it was good for the digestion.

    In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao. It quickly became a cheap and popular drink. Soon afterwards, a factory made the first solid block of sweetened chocolate. Later on, another factory mixed milk and chocolate together. People liked the taste of milk chocolate even better.

    Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie. Favorite desserts are the chocolate cream pie and, of course, an ice cream sundae with hot fudge sauce.

    What is a lifestyle and how is that different from a life? A lifestyle is about brand names and buying identity or fame. Lifestyle gives a false sense of peace and acceptability that comes from others recognizing what you've bought into (as well as bought). If your car, clothes, and home are expensive, you're sophisticated (世故的) and stylish. If you have the right kind of job or go to the right social gatherings, then you receive the insincere approval of others. This means that your self-esteem (自尊) is always at the mercy of others, with no appreciation of you as an individual.

    A life, on the other hand, is very different. A life is what you lead when you know what matters most to you. It is very simple and comes from being connected to what you know is important and being willing to put that first, no matter what others may think. When you create a life vs. a lifestyle, your self-esteem comes from what's inside you, not what others think about you.

    Lifestyle is expensive financially and personally, because it costs a great deal to keep up appearances and do what you think is socially acceptable. A life is not expensive. Rather than using personal or financial resources, a life generates energy and staying power. It's about liberating yourself from the mindless consumption that society expects. It is about making the choices that are in line with your values, instead of using up your bank account or energy for no heart-driven reason.

    How can you make the change? Understand the difference between a life and a lifestyle. Analyze your current lifestyle to see what is costing you in money, time, stress, and energy to maintain it. Let go and make room for what is really important to you, what supports you and brings you joy. Remember who you are from within, not what you own!

    If you love eating and drinking for free and are looking to make some pocket money, there's a job in China with your name on it. A new type of online service allows people to hire others either to eat or drink their favorite treats or satisfy their appetite without the calories that usually come with it.

    Chinese media recently reported on an increasingly popular service on online platform Taobao that's as startling as it is appealing. People can now go online and hire others to consume certain foods and drinks, and ask them to provide video evidence of them eating or drinking the said treats.

    Fees usually range from two to nine yuan ($0.30 - $1.35) plus the cost of the food. It's not exactly a get-rich-quick job, but there are quite a lot of people willing to do it for the free treats alone.

    "Bubble tea drinking" is a particularly popular service, as the chewy tapioca(木薯粉) balls and popping drink is all the rage in Asia these days, but there are also ads from people willing to eat fried chicken or hot pot for anyone willing to pay for them.

    Advertised as being "fat-free" and "free of queues", those who pay for the service will receive the full experience, which includes a 360-degree video of the drink, photos, and a detailed description. Prices of the service are based on the drink's sweetness level, its price, and popularity. Some clients even require a short written review to be sure that the person they hired actually does what they are supposed to.

    Sellers explained that most customers buy their "Bubble tea drinking" service maybe because they're trying to shake off desires while they're on a diet. Drinking bubble tea by proxy may help customers avoid high blood pressure, high blood sugar, and other health problems that the sugar-laden drink may cause.

    So why would anyone pay a total stranger to enjoy a treat rather than consume it themselves? Well, apparently, the online service is so cheap that some people simply do it out of boredom, while others get satisfaction from watching others indulge in their favorite treats.

    This indulging-by-proxy service(代享受服务)has received a lot of attention on social media in China, with some people describing it as the job of their dreams.

    Yoga is an ancient physical and spiritual practice originating in India. The word '"yoga" comes from Sanskrit (梵文) and means to join or to unite, symbolizing the union of body and mind. Today it is practiced in various forms around the world and continues to grow in popularity. Recognizing its universal appeal, the United Nations declared 21 June as the International Day of Yoga in 2014 to raise awareness worldwide of the many benefits of practicing yoga.

    Yoga is an invaluable gift from an ancient tradition. It's not just about exercise but a way to discover the sense of oneness with yourself nature and the world. There is no written record of who invented yoga. Yoga practitioners (从业者) passed down the principles to their students. The earliest written record of yoga is generally believed to have been written by Patanjali, an Indian master who lived somewhere between 2,000 and 2,500 years ago.

    Various yoga types give you multiple choices. Hatha yoga is the most widely practiced type and is excellent for beginners. It is gentle with slow and smooth movements. Kundalini yoga combines a singing session besides body and mental control. Bikram yoga is practiced in a heated room. It is to loosen muscles and to sweat to clean the body and remove symptoms of disease and pain. Ashtanga yoga is taught as a difficult workout where you move quickly from one gesture to another to build strength and patience.

    In recent years, the World Health Organization has urged countries to help their citizens reduce physical inactivity, which is among the top ten leading causes of death worldwide, and a key risk factor for non-communicable diseases, such as cancer and diabetes. Yoga is a proper exercise. It is known for its ability to ease stress and anxiety. It may also help reduce several risk factors for heart diseases and promote a better sleep.
