A young Los Angeles actor in need of a second job to pay his bills has come up with a brilliant way to supplement his income-people walking.

    Chuck McCarthy originally considered becoming a dog walker to earn some extra cash, but soon realized that the job required more than walking dogs on a leash. However, walking people didn't require much when they were out on walks. Chuck realized there was money to be made if he walked people around Los Angeles instead.

    It might sound like a joke, but The People Walker, as he calls himself, is very serious about his new job. For $7 per mile, he offers to walk with clients around L.A., listening to their problems or simply making conversations and offering them a sense of security. At 6-feet, 2-inches, and sporting a bulky figure and bushy beard, Chuck doesn't look like the kind of guy you'd want to mess with.

    Chuck's services are aimed at people who need a motivational boost to go walking, those who don't feel safe walking alone in some areas, and those who are afraid that people might see them walking by themselves and think that they have no friends. “I wear my The People Walker shirt upon request and on the first walk with a new client, so they can be 100% sure it's me,” McCarthy says. However, he admits some people are a bit uncomfortable with this policy, as they don't necessarily want everyone to know that they're being walked.

    So far, Chuck McCarthy has already had another five people walkers employed, covering various areas, like downtown L.A., Hollywood, Eagle Rock, or Fairfax. Once he posted signs around the city, his phone started ringing and clients began rolling in. And with all the free publicity he has been getting in the press lately, more requests are coming.

    While he hopes that his acting career will pick up soon, in the meantime Chuck is very happy with his people walking business. After all, it's literally a walk in the park and it pays the bills.

    Bees and other pollinators（传粉者）  use smells to track down fresh flowers. Air pollutants can weaken those scents（气味）.  Scientists had worried this might make it harder for some pollinators to find a meal.

    Many animals help pollinate plants. Species that do this include bees, butterflies, etc. But for many reasons, the pollinators available to help plants in this way are decreasing. Scientists think a loss of habitat（栖息地）can be one factor. Diseases and exposure to poisonous chemicals also count.

    Jose Fuentes points to air pollution as another possible factor. He's an atmospheric scientist at Pennsylvania State University. In an earlier study, he showed some air pollutants could weaken or destroy scents emitted(发出)by flowers.

    Searching for a meal leaves pollinators out in the open and at risk of becoming other animal's lunch. And any time spent hunting food is time away from their duties back home, like protecting a hive（蜂巢）or nest, explains T'ai Roulston. He's an insect biologist at Virginia University. Roulston worked with Fuentes on the new study.

    In the study, the researchers focused on five kinds of representative scent molecules(分子)plants emit. One molecule they looked at, for example, is called beta-myrcene. Many flowers give off this chemical into the air.  Normally, this gas can travel some 800 meters from its flower source. But in polluted air, this same molecule could travel only half as far.

    Worse still, air pollution might do more than just weaken scent plumes（气味烟云）．Chemical reactions between air pollutants and plumes may transform the flowers' smells, creating new scents. And these scents may be unrecognizable to pollinators.

    That's certainly Fuentes' concern.  So, he says his next research project will look at how insects handle any new flower scent. "It's possible that some insects will change ways to detect and use these new molecules to find food," he says.

    “Children start putting their fingers in their noses as infants,” says Sarah Springer, MD' of Kids Plus Pediatrics in Pittsburgh. “As soon as they have motor control of their fingers, they'll find holes where their fingers can fit. It's not a worry—just a normal part of how they explore and learn.”

    In order to help your child to stop engaging in the behavior it's important to understand why they may start the habit in the first place, according to the University of Michigan Health System. Nose-picking can be a result of boredom, sleepiness, falling asleep, relaxation or coping. In most instances, nose-picking is likely just a phase（阶段）and the child will eventually quit it.

    There isn't much parents can do to stop the behavior of nose-picking, as it's a normal part of being a kid, Dr. Springer says. Parents are advised to ignore the behavior and not show frustration's this won't help encourage your child to stop picking their nose. Instead, Dr. Springer says to help your child learn to blow their nose once they are four or five years old and talk to your child about keeping their hands clean to avoid spreading germs.

    Take note of the season or climate, too, as dry air or cold can increase the occurrence of nose-picking. Parents should use a humidifier（增湿器）in these conditions to help nasal secretions（鼻分泌物）stay moist. Putting petroleum jelly（凡士林）a few times a day inside the nose can help with irritation and minimize picking.

    Once your child enters school, it's inevitable for them to see and pick up bad habits, Dr. Springer said. Nose-picking is a common habit, even among adults and as children age most will realize it's not an acceptable behavior.

    “Nose picking is a normal part of childhood,” Dr. Springer says. “Most kids will become conscious of the social stigma（羞耻）associated with it, and will eventually stop picking, at least in public.”

    There are so many expressions in American English that sound good but are not.

    "Face the music" is a good example. When someone says they have to face the music, it does not mean they are going to a musical show or concert. To face the music means to accept the bad results of an action.

    Imagine a friend asks you to take care of her beautiful red sports car. She gives you the keys and says, "Thanks so much for watching my car while I'm away. But please do not drive it. It is a very fast car and you are not on the insurance (保险)."

    But you do not listen. You want to show it to some friends and pretend(假装) the car is yours. So, you drive it around town one night. As bad luck would have it, you lose control of the car and drive it into a stop sign. The damage is serious. When your friend returns you must tell her what you have done and "face the music".

    The "music" here is the result of your actions. It could be losing her friendship or paying for repairs to her sports car or both. Whatever the music is, you must face it.

    There are other American expressions that mean the same as "face the music".

    To "take your medicine" means to accept the results from something bad you have done. And if someone says, "You made your bed. Now lie in it." He means you created a bad situation and now you will experience the results, or as we say in American spoken English, you must deal with it!

    "Pay the piper" also means the same as "face the music". But, that expression has its own very interesting beginning. We will talk about that in the next Words and Their Stories.

    No one knew Prince Edward Street as well as Pierre Dupin. He had delivered milk to the families on the street for thirty years. For the past fifteen years a large white horse named Joseph pulled his milk wagon. Joseph was a gentle horse with beautiful spirit shining out of its eyes, so Pierre named him after Saint Joseph.

    Every morning at five, Pierre arrived at the milk company's stables to find Joseph waiting for him, Pierre would call, "Good morning, my old friend." as he climbed into his seat, while Joseph turned his head toward the driver. And the two would go proudly down the street. Without any order from Pierre, the wagon would roll down three streets. Then it turned right for two streets, before turning left to Saint Catherine Street. The horse finally stopped at the first house on Prince Edward Street. There, Joseph would wait perhaps thirty seconds for Pierre to get down off his seat and put a bottle of milk at the front door.

    Pierre knew every one of the forty families that got milk. The cooks knew that Pierre could not read or write; so, instead of leaving orders in an empty milk bottle, they simply sang out if they needed an extra bottle.

    Pierre also had a wonderful memory. When he arrived at the stable he always remembered to tell Jacques, the foreman(领班) of the stables, "The Pacquins took an extra bottle this morning; the Lemoines bought a pint of cream …" Most of the drivers had to make out the weekly bills and collect the money. But Jacques, liking Pierre, never asked him to do this.

    One day the president of the milk company came to inspect the early morning milk deliveries. Jacques pointed to Pierre and said："See how the horse listens and how he turns his head toward Pierre? See the look in that horse's eyes? You know, I think those two share a secret. I have often felt it. He is getting old. Maybe he ought to be given a rest, and a small pension."

    "But of course," the president laughed. "He has been on this job now for thirty years. All who know him love him. Tell him it is time he rested. He will get his pay every week as before."

    But Pierre refused to leave his job. He said his life would be nothing if he could not drive Joseph every day. "We are two old men," he said to Jacques. "Let us wear out together. When Joseph is ready to leave, then I too will do so."

    Then one cold morning Jacques had terrible news for Pierre. Jacques said,"Pierre, your horse, Joseph, didn't wake up. He was very old, Pierre." Jacques said softly. "He is over in his stall, looking very peaceful. Go over and see him." Pierre took one step forward, then turned. "No … no … I cannot see Joseph again. You … you don't understand, Jacques."

    For years Pierre had worn a large heavy cap that came down low over his eyes. It kept out the bitter cold wind. Now, Jacques looked into Pierre's eyes and he saw something that shocked him. He saw a dead, lifeless look in them.

    "Take the day off, Pierre," Jacques said. Pierre walked to the corner and stepped into the street. There was a warning shout from the driver of a big truck … there was the screech(尖锐的刹车声) of rubber tires as the truck tried to stop. But Pierre heard nothing.

    Five minutes later a doctor said, "He's dead … killed instantly."

"I couldn't help it," the truck driver said. "He walked in front of my truck. He never saw it, I guess. Why, he walked as though he were blind."

    The doctor bent down. "Blind？Of course, this man has been blind for five years."  He turned to Jacques, "Didn't you know he was blind？"

    "No …no …" Jacques said softly. "None of us knew. Only one … only one knew－a friend of his, named Joseph … It was a secret, I think, just between those two."

    A man went into a restaurant and sat down at a table. He ordered the most expensive dishes. The waiter served the meal. He ate it with great joy. Then a small boy came in and sat at his table.

    The waiter came up and said to the man, "What would your little boy like, sir?"

    "Oh, just an ice cream," the man told him. Then he stood up and said to the waiter, "I'm just going out to buy a newspaper."

    He left the restaurant. The waiter gave the boy an ice cream. The boy took it and then stood up and walked to the door. The waiter ran towards him.

    "Excuse me," he said, "But your father hasn't come back and he hasn't paid for his meal or for your ice cream."

    "He's not my father," the boy said. "I don't know him at all."

    The waiter was puzzled. "What do you mean?" he asked.

    "The man came up to me in the street," the boy said, "He asked me if I liked an ice cream. I told him I did. Then he told me to come into the restaurant at 2 o'clock and sat down at his table. He said he'd give me one."
