Studies show that you may be lied to every day anywhere from 10 to 200 times. We say, “Nice song.” “Honey, you don't look fat in that, no.” But another study showed that strangers lied three times within the first 10 minutes of meeting each other. We lie more to strangers than we lie to coworkers. Men lie eight times more about themselves than they do about other people. Women lie more to protect other people. If you're married, you're going to lie to your wife/ husband in one out of every 10 communications. If you're unmarried, that number drops to three. But look, if at some point you got lied to, it's because you agreed to get lied to. Truth about lying: lying's a cooperative act. Not all lies are harmful. Sometimes we're willing to get lied to for social dignity(尊严), maybe to keep a private secret.

    Lying is complex. It exists in our daily and business lives. We're deeply disturbed by the truth. We explain it, sometimes for very good reasons, other times just because we don't understand the gaps between ideals and realities in our lives. We're against lying, but secretly we're for it in ways that our society has practiced for centuries and centuries. It's as old as breathing. It's part of our culture and history. Think the stories from Dante, Shakespeare, the Bible, News of the World.

    Lying has great value to the evolution of human beings. Researchers have long known that the more intelligent the species, the more likely it is to lie. We humans like to become leaders. It starts really early. How early? Well, babies will pretend to cry, pause, wait to see who's coming and then go right back to crying. One-year-olds learn hiding truth. Five-year-olds lie outright and try to control through flattery (奉承). Nine-year-olds, masters of covering up.

    So what do we do about lies? Well, there are steps we can take to guide our way through the bushes. Trained lie spotters (检测员) get to the truth 90% of the time. The rest of us, we're only 54% right. There are clever liars and stupid liars, but there're no real creative liars. While lying, we all make the same mistakes, and we all use the same techniques.

    One silly question I simply can't stand is “How do you feel?” Usually the question is asked of a man in action—a man on the go, walking along the streets, or busily working at his desk. So what do you expect him to say? He'll probably say, “Fine, I'm all right,” but you have put a bug in his ear —maybe now he's not sure. If you are a good friend, you may have seen something in his face, or his walk that he overlooked that morning. It starts worrying him a little. First thing you know, he looks in a mirror to see if everything is all right, while you go merrily on your way asking someone else, “How do you feel?”

    Every question has its time and place. It's perfectly acceptable, for instance, to ask “How do you feel?” if you're visiting a close friend in the hospital. But if the fellow is walking on both legs, hurrying to make a train, or sitting at his desk working, it's no time to ask him that silly question.

    When George Bernard Shaw, the famous writer of plays was in his eighties, someone asked him “How do you feel?” Shaw put him in his place. “When you reach my age,” he said, “either you feel all right or you're dead.”

    Honeybees can do three kinds of jobs.

    It is one of the most unusual insects in the world. Bees are special because they divide up their honeybee work. Each bee has a certain job to do.

    The busiest bee is the worker. Workers build the nest, called a hive. Inside the hive, workers make a honeycomb from wax(蜂蜡). They store honey there for food. Workers are always cleaning and fixing the hive. They even stand at the opening and fan their wings to cool the hive. Worker bees will attack anything—even people—to keep their hive safe, if need.

    Another kind of bee is the drone(雄蜂). Drones are male bees, and their job is to fly with the queen bee and mate with her. After the queen mates, the worker bees drive the drones away. The drones then starve to death.

    The third kind of bee is the queen. Each hive needs only one queen, and her job is laying eggs. She can lay as many as 2, 000 eggs a day.

    Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago. Post-it Notes, the pieces of paper that you can stick almost anywhere and then remove without leaving any sign that they are there, are an example of such an invention.

    Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Corporation. The idea for the product came from an upsetting experience he often had while singing in his church choir. Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. He knew he needed a bookmark that would stay where he put it, but that he could remove without damaging the pages.

    Around that time, Fry heard about a new adhesive(粘合剂) that a colleague, Dr. Spence Silver had created. This adhesive was special because it was sticky, but not too sticky. It was strong enough to hold papers together, but weak enough not to tear the paper when it was removed. Fry saw that the new adhesive could help solve his bookmark problem. One morning, Fry put some of the adhesive on the edge of a piece of paper. Just as he hoped, it made a perfect bookmark.

    A short time later, Fry realized that his new invention had even more uses than being a great bookmark. He came to this realization when he wrote a note on one of his new “bookmarks” and attached it to a report he was going to give to a colleague. Soon, co-workers were asking Fry for more sample of his invention so that they could use the new type of notes themselves.

    Fry and some other people at 3M believed so much in the new product that they persuaded the company to give away thousands of the sticky pieces of paper for trial use. When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off.

    Bright Side did some research on many places throughout the world where you can buy a house for 1 dollar or for free!

    Roubaix, France

    If you like France, Roubaix located in the north of France is just for you. The local authorities want it to be populated and attractive. You can buy a small house in the industrial district for just $1. The buyer is supposed to live in this house for 3 years.

In the story of "The crow and the Pitcher" from Aesop's Fables, a thisty crow (乌鸦)drops stones into a narrow jar to raise the low level of water inside so he can take a drink.

Now scientists have evidence to back up that story. Crows actually do understand how to make water displacement (移位) work to their advantage, experiments show. The results suggest that the birds are, at least in some aspects, as smart as first-graders.

Researchers, led by Sarah Jelbert at the University of Auckland in New Zealand, presented six crows with tubes filled with water. Inside the tubes, a worm or piece of meat on a piece of wood was floating, just out of reach of the crow. In front of the tubes, the researchers arranged several rubber erasers that would sink, and some plastic objects that would float. The crows found out that they could drop the erasers into the tubes in order to raise the water level and get their snack.

However, the birds handled awkwardly in experiments in which they could choose to drop objects in either a wide tube or a narrow one to get a snack, the researchers said. Dropping objects into narrow tube would lift the water level by a greater amount and put the treat within reach after just two drops; while it took around seven drops to raise the snack to the same level in the wide tube. The crows obviously didn't realize this, and most of them went for the wide tube first.

Previous studies showed that chimps and human children can solve similar tasks. In a 2011 study, chimps and kids found out that they could put water into a tube to reach a peanut that was floating in a small amount of water at the bottom.
