If you live in the U.S., you're probably used to throwing banana peel into the trash. But people in other countries, including India, have been taking advantages of their nutritional benefits for many years.

    While the flesh of a banana is soft and sweet, the skin is thick, hard and slightly bitter. To eat the peel, you can fry, bake, or boil it for at least 10 minutes. Also, the riper bananas get, the thinner and sweeter banana peel will become. That's because of a natural plant hormone(激素) called ethylene(乙烯) that fruits release as they ripen. Ethylene interacts with the sugars and fiber in the banana skin, changing complex sugars into simple sugars and breaking down pectin, a form of fiber in bananas that keeps them stiff. That's why the older your banana is, the flimsier(不结实的) it feels.

    The sweet flesh of a medium-sized banana contains great percentages of your daily recommended intake of various nutrients, such as:

·12% of your daily fiber, which helps with digestion and may help lower your risk of diabetes(糖尿病)

·17% of your vitamin C, which is important for your immune system as well as your growth

·20% of your vitamin B6, which aids the body's ability to turn food into energy

·12% of your potassium, which helps with the development of cells, tissues, and organs throughout the body

    If you eat the skin along with the flesh, you will get an even bigger increase in these same nutrients.

    Eating the peel is not only good for your body but also better for the earth. The average American ate 11.4 pounds of bananas in 2014. Since a medium-sized banana weighs about 0.3 pounds, that equates to about 38 bananas per person, or about 12 billion for the whole of the U.S. And since most of us throw away the peel, that also means a lot of organic waste.

    Do you still remember your favorite poem from high school or some other important periods in your life？Why is it that decades later it still stands out in your mind？Probably the main reason is that some aspect of that poem resonates (引起共鸣) with you. In the same way, you too as a school leader can touch the hearts of your teachers and students.

    Poetry allows us to experience strong spiritual connections to things around us and to the past. The power that poetry has displayed over time and across cultures actually satisfies this common need of the human heart and soul.

    As one of the oldest art forms, poetry has successfully connected various parts of humanity (人性) from one generation to another. Referring to poetry, Hillyer makes a simple yet meaningful statement, “With this key mankind unlocked his heart.”

    School leaders can find and make use of the value of poetry for themselves, their students and their teachers. Beyond the simple use of poetry, techniques of poetry such as repetitions can be used to take advantage of the power of language to transform communication, create meaning and a culture of care and attention.

    Since schools are mainly about people and relationships, school leaders, like poets, are required to inspire and encourage the human heart. The use of poetry—or even of some techniques of poetry—in school leadership not only helps to improve communication, but also serves to meet the human need for inspiration.

    When it comes to medical care, many patients and doctors believe “more is better.” But what they do not realize is that overtreatment—too many scans, too many blood tests, too many procedures—may bring harm. Sometimes a test leads you down a path to more and more testing, some of which may be attacking, or to treatment for things that should be left out.

    Terrence Power, for example, complained that after his wife learned she had Wegener's disease, an uncommon disorder of the immune system(免疫系统), they found it difficult to refuse testing recommended by her doctor. The doctor insisted on office visits every three weeks, even when she was feeling well. He frequently ordered blood tests and X-rays, and repeatedly referred her to experts for even minor complaints. Even when tests came back negative, more were ordered, and she was hospitalized as prevention when she developed a cold. She had as many as 25 doctor visits during one six-month period. The couple was spending about $30,000 a year for her care.

    After several years of physical suffering and near financial ruin from the medical costs, the couple began questioning the treatment after discussing with other patients in online support groups. “It's a really hard thing to determine when doctors have crossed the line,” Mr. Power said. “You think she's getting the best care in the world, but after a while you start to wonder: What is the purpose?” Mr. Power then spoke with his own primary care doctor, who advised him to find a new expert to oversee Mrs. Power's care. Under the new doctor's care, the regular testing stopped and Mrs. Power's condition was stable. Now she sees the doctor only four or five times a year.

    The Taj Mahal, in Agra, India, is one of the most brilliant structures on Earth. It is nearly 400 years old. Emperor Shah Jahan had it built in memory of his wife. It took about 20 years to build the monument. Some 20,000 workers and 1,000 elephants helped get the job done. Today, the Taj Mahal is not just a symbol of cultural history. It's also India's most famous tourist attraction. About 8 million people visit it each year.

    But pollution is turning the white marble monument shades of green, yellow, and brown. The Taj Mahal stands on the polluted Yamuna River. Insects are attracted to the dirty water. They leave greenish droppings on the building. Air pollution is also a big threat. Factories and cars release pollution into the air. It sticks to the Taj Mahal's suidEace. In the 1990s, India's Supreme Court ordered hundreds of factories near the monument to close. Also, car and bus traffic was restricted. From time to time, workers clean the Taj Mahal. But doing so is difficult, expensive, and time-consuming. And it doesn't prevent the discoloration.

    On July 11, India's Supreme Court gave the city of Agra a warning: "Either you destroy the Taj Mahal or you restore it". Authorities in the city submitted a draft of an action plan on July 24. It suggests banning plastics and construction from the area. It also calls for the closing of more factories.

    "In order to preserve the Taj Mahal, people must come together to work toward a solution. There needs to be positive pressure on people to act. We need to act immediately," Sachchida Tripathi says. He worked on a 2014 study of pollution at the Taj Mahal. "We are trying," he adds, "but we need to try more."

    I want to talk about a soldier. I saw him yesterday as my husband and I were enjoying a wonderful lunch in the cave-like dining room of an old hotel.

    It is hard to imagine being comfortable in a room that probably seats a thousand, but the real magic of the place is its wonderful setting. Every comer is a wood and stone masterpiece, with high glass windows that look out to the huge cliffs of the valley.

    A man entered with his family and took a seat. He wasn't in uniform, but he walked with the dignity of a soldier, and a slight limp (瘸). My suspicion was confirmed when he removed his hat and placed it on the table where I could see it. Embroidered (绣) on the cap were the words: "Iwo Jima Survivor".

    As they were waiting for lunch, the others talking happily, this gentleman was stating out of the window. He was content to be left out of the conversation and allowed to take in the wonderful and impressive view of the waterfall.

    I watched him, and imagined how much horror he had seen in the war. What losses did he suffer, and how many friends did he lose? What he had witnessed should have given him a good reason to lose faith in the world. Yet this tired soldier was smiling at the sky, at the sun and the roaring of the waterfall. Somehow, after everything, the world was still beautiful to him.

    I walked over to him and said, "Excuse me, sir. I'm sorry to interrupt, but I saw your hat, and I just wanted to say thank you for serving."

    He looked up at me, surprised, and said proudly, "You're welcome, and thank you, too."

    I told him I would go home and tell my children about this experience that I'd met him.

Cala didn't like us. Any of us. We didn't do anything to offend her and she didn't know us but that didn't matter; she still didn't like us.

As new teachers in the Emirati school, we Westerners greeted her every day. She ignored us. She came into our rooms and bypassed us as she shook hands with all the non-Westerners. Whenever we saw her, she avoided eye contact with us. Eventually, we stopped trying to befriend her.

I wouldn't say her nationality but her friends had been fired from the school. We had been employed in their places and that was enough for her to have nothing to do with us.

Well after 16 months in the school we had a secret friend gifting. To my surprise, I drew her name from the glass jar and that meant she was my secret friend. My role was to buy her a gift and say something about her when we publicly acknowledged who our secret friend was.

I decided to gift her a coloured bangle (手镯). I added a postcard and wrote "Love and Blessings, Rose Marie.

Then came the day. We all gathered in the meeting room. When you gave your gift, you said a few kind words about your secret friend and passed the gift to her. What could I say? Everyone knew she didn't like the Westerners. She taught music in the school so I said "My secret friend is someone who brings music to our ears every day." She came forward with a huge warm smile. She hugged me and kissed me on both cheeks and accepted my gift.

Since then, she smiles often. We hug and shake hands when we meet. I have seen her wear my gift several times and I am so pleased.
