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.

    Travis is the manager of G&G where he is responsible for forty employees (雇员)and profits (利润) of over $2 million per year. He's never late to work. He does not get upset on the job. When one of his employees started crying after a customer screamed at her, Travis took her away. "Your working uniform is your shelter," he told her. "Nothing anyone says will ever hurt you. You will always be as strong as you want to be."

    Travis picked up that lecture in one of his G&G training courses, an education program that began on his first day and continues throughout an employee's occupation. The training has, Travis says, changed his life. G&G has taught him how to live, how to focus, how to get to work on time, and how to master his emotions (情绪). Most importantly, it taught him willpower.

    At the center of that education is an extreme focus on an all-important habit; willpower. Dozens of cases show that willpower is the single most important habit for a person's success.

    And the best way to strengthen willpower is to make it into a habit. "Sometimes it looks like people with great self-control aren't working hard—but that's because they've made it automatic," Angela Duckworth, one of the University of Pennsylvania researchers said. "Their willpower occurs without them having to think about it."

    The company spent millions of dollars developing programs of study to train employees on self-control. Managers wrote workbooks that serve as guides to how to make willpower a habit in workers' lives. Those courses arc, in part, why G&G has grown from a sleepy company into a large one with more than seventeen thousand stores and profits of more than $10 billion a year.

    Billionaire Bill Gates has offered the many thousands of graduates some career and life advice. Over a series of 14 tweets in his Tweeter posted last Monday, the world's richest man used the words “impact”, “happiness” and “progress”. He did not mention money. Instead, he told the graduates what jobs he would be looking for if he started out today.

“AI (artificial intelligence), energy and bio-sciences are promising fields where you can make a huge influence”, he wrote. Earlier this year, Gates—who famously dropped out of Harvard to found Microsoft—said that artificial intelligence had “ phenomenal” potential, and “anything connected with that would be an exciting lifetime career.” In the same speech at Columbia University, he said there is a huge growing demand in the energy field to develop reliable, cheap and clean energy.

    As well as urging new graduates to surround themselves with people who challenge you, teach you, and push you to be your best self, Gates reminded them to think of others, especially the less fortunate.

    He wrote that it had taken him decades to learn about the world's worst unfairness and described this lack of early understanding as his one big regret. “You know more than I did when I was your age,” he wrote, “ You can start fighting unfairness, whether down the street or around the world sooner.”

    He finished by asking graduates to consider the progress human has already made, saying that he believe the world is getting better. “ That matters because if you think the world is getting better, you want to spread the progress to more people and places.”

    Ninety years ago a man named Howard Carter made a great find. But he didn't discover an unknown people group or a new plant. He found the resting place of a king.

    People had seen signs of King Tutankhamun's tomb (坟墓) but had never found it. Finally, Carter's team discovered a set of steps that led down to some underground rooms. There Carter found the king's body and many of his treasures.

    Carter recorded his first impression in his popular book, The Tomb of Tut-Ankh-Amen：

At first I could see nothing, the hot air coming from the room causing the candle light to flicker (闪烁), but later, as my eyes grew used to the light, details of the room within appeared slowly and clearly, strange animals and gold—everywhere the light of gold... I was struck speechless with amazement, and when Lord Carnarvon, unable to stand the silence any longer, asked anxiously,  “Can you see anything?” it was all I could do to get out the words, “Yes, wonderful things.”

    The discovery has made King Tutankhamun, Tut for short, one of the best-remembered kings of Egypt. Tut became king when he was only 9 years old and ruled ancient Egypt from 1332 to 1323 B.C. No one is sure why, but he died suddenly before he turned 20. Because he died so young, there wasn't time to prepare a great tomb for him. So he ended up with a smaller tomb. Its small size was actually the reason why it stayed hidden for so long. And, Tut's tomb was not like other Egyptian kings'—it was not as damaged by time or robbers as other tombs. King Tut's tomb remains the best-kept royal (皇室的) tomb ever discovered. The discovery of this little tomb has helped people learn a great deal about ancient Egypt.

    My wife and I went to this vegan(严格的素食主义的)restaurant to give it a try.As we were eating our pepper and salt tofu, a young lady named Debra walked in. She wasn't aware that the place is vegan and was looking for some meat. My wife and I talked up the place and invited her over to try some of our tofu. Debra tried it, nodded and went out.

    After a few minutes, she and her mother both walked back in. We were having the rest of our meal at that time, so we told her what we had ordered. Debra then asked the waitress to just repeat our order for them. Next, Debra said, "And we want to pay for their meal", pointing to my wife and me. We tried to say no, but Debra wouldn't listen.

    That was not the end of it. Hugs were in order. Debra came over to our table and my wife got up to hug her. Debra hugged my wife and put $100 into her hand. My wife firmly said NO, but Debra insisted. Debra kept talking about our kindness, and we did the same about hers and her mother's. With tears in the eyes, the workers were blown away by this whole exchange between four strangers. I left the waiters a tip that would cover all of our meals and we were on our way.

    I've been witnessing so much kindness, especially over the last few years, as I began to pay more attention. We now have a new favorite restaurant and every time we go there my plan is to pay for someone else's meal.

    Have you ever been into a cave? If not, please follow us and explore some of the most beautiful caves from around the world!

    Marble Caves

    Located in the center of Lake General Carrera, the Marble Caves in Chico, Chile, are only accessible by boat. The surrounding crystal clear waters allow visitors to see the rock formations beneath them while the rock ceilings above change color(depending on the writer levels and the season). The best time to visit: during sunrise and sunset, when the sun's rays light up the cave walls, making it an experience to remember.

    Reed Flute Cave

    Reed F1ute Cave known as "the Palace of Natural Arts" is located in the northwest of Guilin in southern China. The limestone cave offers a grand fairyland of stalactites(钟乳石), stone pillars, stone curtains, birds, plants and animals in fantastic shapes and colors.

    Fingal's Cave

    This incredible sea cave is located on the uninhabited island of Staffa in Scotland. The cave's size, shape, and naturally­arched(拱形的) roof combine with the waves to create strange sounds that enhance its cathedral­like atmosphere.

    The Blue Grotto

    The Blue Grotto is the symbol of Capri. It is a sea cave found on the coast of the island and is a well-known spot to all who visit the area. This cave is unique for its brilliant blue light which comes from two sources: the entrance to the cave and a bigger hole beneath the entrance. When viewed from inside the cave, the entrance appears as a brilliant white light just above the waterline, while the underwater hole, which is the larger source of light, provides a blue light.
