You might make a disgusted face when you notice that the person waiting in their car at the red light next to you is picking their nose,but admit it,you do it too.And while it might be the natural option when there isn't a box of tissues around,it can be bad for you.The main reasons people feel the need to pick their nose is to clear it of dried liquid,stop an itch（痒）,or just because it feels good.Boogers（鼻屎）form when dried liquid and cilia,the tiny hairs that line the nostrils（鼻孔）,trap the dust,dirt,and other things.When boogers build up in your nose,it can be uncomfortable,and sometimes just blowing into a tissue doesn't do the trick.

    Otolaryngologist Erich P.Voigt, MD ,told Business Insider that picking your nose can cause injuries and bleeding within your nostrils.That's not terribly damaging,but when the bacteria from your hands get into your body,it can cause a cold and flu.So doctors strongly suggest not picking the nose.

    If dry winter air is causing the dirty liquid to harden in your nostrils,making you want to pick,consider damping the air at home,or taking a steam shower to soften things up in there.

    Children, who are most famous for having a finger up their nose,sometimes don't realize how much injury they're causing,and sometimes it.can lead to nose bleeds.

    So, next time you go to pick your nose,think about how many bacteria are on your hands and in your boogers, and maybe reach for a tissue instead.Even if you 're alone,and not waiting for the light to turn green,please,use a tissue.

    Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I've ever had: Be bold and brave — and mighty (强大的) forces will come to your aid.

    Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.

    Boldness means a decision to bite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas — even physical strength greater than most of us realize.

    Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player. “In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,” said Tim. “I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet — and stopped him cold.”

    Boldness — a willingness to extend yourself to the extreme—is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disappointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.

    So, always try to live a little bit beyond your abilities—and you'll find your abilities are greater than you ever dreamed.

    62-year-old Zhang Jianxing has been searching the ancient forests of the Shennongjia National Nature Reserve for over two decades.

    Jianxing began living in the 3,200-square-kilometer mountain range in 1994, after becoming fascinated with the Yeren(also Chinese Wild Man), a 6-foot-tall humanoid creature covered in thick red-brown fur. References of the so-called Chinese Wild Man date back to the Zhou Dynasty in the works of classical Qu Yuan.

    For 10 months out of every year, for the last 22 years, Jianxing has been living deep in the Shennongjia National Nature Reserve, hoping to meet the Yeren. Dressed in military gear and armed with a camera, he constantly looks for clues of the creature, living off the land and sleeping in abandoned homes and empty caves. To him, the Yeren is more than just an old myth, it's a branch of scince, one that he has been studying for a very long time.

Jianxing claims he has collected enough evidence of the Wild Man's existence—over 100 hair samples and 3,000 photos of large footprints—adding that he even came close to seeing it for himself no less than 19 times. And he is not alone in his beliefs. The Wild Man Research Association—-yes, there is such a thing—records show reports of Yeren encounters from over 400 locals.

    But with no concrete evidence to prove the existence of the Wild Man, most scientists regard it as nothing more than a legend.

Jianxing also added that the local government in Hubei is relying on the Yeren to boost its tourism revenues. In 2012, the Shennongjia Nature Reserve signed an agreement with Beijing to promote holidays for Yeren hunters.

    “Has anyone seen Charge?” I asked, only half expecting a reply. The kids were running around the house, each doing their own thing, and my husband was watching the football game. Since she had only been out of sight for a few hours, I wasn't overly concerned. I thought she must be under one of the kids' beds, hiding from all the mess that was normal for a Sunday afternoon in our home.

    ①

    Charge was not good-looking, to put it kindly. It wasn't her fault; she was simply gifted with the worst appearance traits（特征）in her background.

    My husband had found Charge wandering along the freeway one day on his way home from work. She looked as though she hadn't eaten in weeks, so he stopped and fed her with bits of his leftover lunch. Not knowing what to do, he brought her home with the hope of finding her owners or at least a loving family that would take her. However, once she was in the house, the kids were determined not to let her go. After a day or two of begging, we unwillingly gave in and told them we could keep her.

    After observing her actions for days, I found she was extremely distrustful and afraid of everyone. In time, though, she came to love the kids and slept on their beds every night. I wondered if what she had experienced had conditioned her to be protective of those who were hurting. Every time the kids cried, Charge would run to them and gently offer her comforting paw（爪子）. Unlike our cat, who had recently given birth to five kittens, Charge would have been a great mother.

    ②

    When I was finally able to get everyone's attention at the dinner table, I asked again if anyone had seen Charge. After a unanimous（异口同声的）“No”, I decided to take a look around the neighborhood.

    ③

    “Charge!” I cried, because there she was in the closet! She looked up at me from inside the little cats' box as if to say,“ Shhh, I just got them to sleep!”

    We usually kept the closet door open a bit so our mamma cat could go in and feed her kittens, but she always left as soon as she finished nursing. Obviously, Charge knew they needed more mamma time and was more than willing to help out.

    ④

    The kids smiled upon seeing the dog with the kittens. My husband shook his head and said, “Only you, Charge. Only you!”

    Charge continued to mother the kittens until they were placed in their new homes. Charge may not have been an attractive dog, but she truly had her inner beauty.

    Blue Planet It's latest episode focuses on how plastic is having a devastating effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, the oceans are drowning in plastic.

    Though it seems now that the world couldn't possibly function without plastics, plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s, the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.

    We put all these plastics into the environment and we still don't really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.

    And it's not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning in the same breath as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don't have to remake our planet energy system.

    This is not a problem where we don't know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to dispose (处理) of it. We know how to recycle. We can all start by thinking twice before we use single-use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag--when taken collectively, these choices really do make a difference.

    If you are in charge of a project, the key to success is getting everyone to want to help you. As a director, I point, I suggest, I gently push the actors in the direction I want them to go. In the 1986 movie, "Nothing in Common", Jackie Gleason's character, Max Basner, gets fired from his job as a clothing salesman. The scene, shot on a boat, shows Max's despair about being out of work. I was looking for some gesture that would allow Max to show his feelings.

    Jackie had far more experience at everything than I did, and at first I was frightened. What could I possibly tell "The Great One" about acting? Out of fear I decided to direct by suggestion, and I sat down with Gleason to talk about the scene. "So Max is sad, right?" I said.

    Gleason nodded.

    "And he's probably still carrying his pens with his name on them—the ones he used to hand out to his customers, right?"

    Gleason nodded.

    "So what would you want to do with the pens after you were fired?"

    He was silent for a moment. "Why don't I throw them overboard?"

    I stood up and turned towards the crew. "Hey, everybody, Jackie has a wonderful idea. Let's shoot it."

    After filming the scene, Gleason called me over and said with a smile. "Garry, what kind of wonderful idea am I going to have tomorrow?"
