Retired nurse Sue Collins was just beginning the second length of her local pool when her morning swim suddenly became anything but a pleasure.

    Two months ago Sue, 69, who has never suffered from asthma or any other breathing problem in the past, suddenly found herself hard for breath.

    “I felt as if my throat and oesophagus (食道) were closing up,” says Sue.

    Sue is convinced the problem is related to the indoor swimming baths. “I spend half the year in Turkey and swim every day outside in a pool or the sea there and never have this problem,” she says.

    She may be right, because although a trip to the pool is the perfect exercise for many, the chlorine (氯气) used to keep the water free from germs can lead to problems.

    But in most cases it's not the chlorine that causes problems, but the by-products formed when chlorine interacts with other substances — and this is mostly due to people not showering before they enter the pool.

    “This then poisons the water for them and for others,” says Dr. Hull. “The chlorine interacts with sweat and urine(尿素) on the skin and forms by-products called chloramines that float above the surface as a gaseous solution that can be inhaled in.”

    Chloramines are heavier than air so hang over the water where they are easily breathed in. Some believe they may cause lung disorders. A Swedish study in 2013 examining the health of 146 workers at 46 indoor pools found that 17 per cent had airway trouble at work — but no problems at home.

    As Dr. Hull says: ‘People need to remember that showering isn't just for them. It is for the greater good.'

    The human athlete has a special trick that no other animal has. It is called self-talk. Athletes talk to themselves to warm up, to focus and to help themselves believe they will win. A few simple words like “I can do it!” and “It is now or never!” can make the difference between winning gold or not.

    Self-talk is also used by speakers, actors and other performers. Before a speech, politicians believe that their words will win votes. And, self-talk helps students stay calm even when stumped by hard exam questions. Self-talk is a life skill you can use wherever you are, whenever you need it.

    The whole idea of talking to themselves seems strange to many people. Imagine your teacher saying, “For homework, talk to yourself for half an hour tonight.” You might think he is playing a joke on your class. Instead, adults teach kids all about talking to other people. There are many books on why, when, what and how to communicate with the rest of the world. Thus, you can grow up knowing a lot more about people around you than about yourself.

    It is good to speak and listen to others. But there is great value in making time to listen to yourself. When you do, you get to know yourself better. Along the way, you may discover the power you have for using words well.

    Such ideas are so exciting to psychologists that they have been trying to learn more about self-talk. In the study, people found certain lost items at home more easily when they talked to themselves while searching for the things.

    It is natural that young people are often uncomfortable when they are with their parents. They say that their parents don't understand them. They often think that their parents are out of touch with modern ways, that they are too serious and too strict with their children, and that they seldom give their children a free hand.

    It is true that parents often find it difficult to win their children's trust and they tend(倾向) to forget how they themselves felt when young.

    For example, young people like to act on the spot without much thinking. It is one of their ways to show that they have grown up and they can face any difficult situation. Old people worry more easily. Most of them plan things in advance, at least in the back of their minds, and do not like their plans to be upset by something unexpected.

    When you want your parents to let you do something, you will have better success if you ask before you really start doing it.

    Young people often make their parents angry with their choices in clothes, in entertainment and in music. But they do not mean to cause any trouble; it is just that they feel cut off from the older people's world, into which they have not yet been accepted. That's why young people want to make a new culture of their own, and if their parents don't like their music or entertainment or clothes or their way of speech, this will make the young people extremely happy.

    Sometimes you are so proud of yourself that you do not want your parents to say “yes” to what you do. All you want is to be left alone and do what you like. It is natural enough, after being a child for so many years, when you were completely under your parents' control.

    If you prefer to control your life, you'd better win your parents over and try to get them to understand you. If your parents see that you have a high sense of responsibility, they will certainly give you the right to do what you want to do.

    You've probably heard such reports. The number of college students majoring in the humanities (人文学科) is decreasing quickly. The news has caused a flood of high-minded essays criticizing the development as a symbol of American decline.

    The bright side is this: The destruction of the humanities is, finally, coming to an end. No more will literature, as part of an academic curriculum, put out the light of literature. No longer will the reading of, say, "King Lear" or D.H. Lawrence's "Women in Love" result in the annoying stuff of multiple-choice quizzes, exam essays and homework assignments.

    The discouraging fact is that for every college professor who made Shakespeare or Lawrence come alive for the lucky few, there were countless others who made the reading of literary masterpieces seem like two hours in the dentist's chair.

    The remarkably insignificant fact that, a half-century ago, 14% of the undergraduate population majored in the humanities (mostly in literature, but also in art, philosophy, history, classics and religion) as opposed to 7% today has given rise to serious reflections on the nature and purpose of an education in the liberal arts.

    Such reflections always come to the same conclusion: We are told that the lack of a formal education, mostly in literature, leads to numerous harmful personal conditions, such as the inability to think critically, to write clearly, to be curious about other people and places, to engage with great literature after graduation, to recognize truth, beauty and goodness.

    Literature changed my life long before I began to study it in college. Books took me far from myself into experiences that had nothing to do with my life, yet spoke to my life. But once in the college classroom, this precious, alternate life inside me got thrown back into that dimension of my existence that bored me. Homer, Chekhov and Yeats were reduced to right and wrong answers, clear-cut themes and clever interpretations. If there is anything to worry about, it should be the disappearance of what used to be an important part of every high-school education: the literature survey course, where books were not academically taught but thoroughly introduced—an experience unaffected by stupid commentary and useless testing.

    The literary classics are places of quiet, useless stillness in a world that despises (鄙视) any activity that is not profitable or productive. Literature is too sacred to be taught. It needs only to be read.

    Soon, if all goes well and literature at last disappears from the undergraduate curriculum—my fingers are crossed—increasing numbers of people will be able to say that reading the literary masterworks of the past outside the college classroom, simply in the course of living, was, in fact, their college classroom.

    Which country can you travel to in 2020 that will allow you to go for longer, enjoy a higher standard, and save more money? The following destinations offer accommodation, transportation, and food for less.

Kyrgyzstan, $25/day

    Kyrgyzstan is the choice for most travelers interested in trying out Central Asia, and most well-suited to travelers of all budgets. Food is cheap, so is getting around using the minibuses. You can find hostels and local home stays for less than $10. Meals cost $4 – $8 per day.

    Romania, $33/day

    If you are planning a European trip that's affordable and a little bit off the beaten path, Romania is perfect for you. Unlike other popular places, many charming towns here remain unknown to most foreigners. You can also take free walking tours in the numerous historical sites. Hostels run $10 – $15 per night, food is hearty and delicious, and the public transportation is reliable and affordable. Meals cost $10 – $15 per day.

    Arizona & Utah, $55/day

    For an American Southwest road trip, you'll spend an average of $110/day when you are solo. If you have just one other person, you'd be able to split the costs almost perfectly in half. If you have two other people along, take it down to one third and so on. The more the merrier.

    South Africa, $40/day

    Any hostels in South Africa are in beautiful settings and each has a unique personality, and affordable too. Food can get expensive. To save money, cook your own food. Grocery stores are plentiful and have reasonable prices. By at least cooking your own breakfast, you can save a lot of money. The best (and possibly cheapest) way to get around the country is to rent a car and share with 3 other people. Meals cost $12 – $15 per day.
