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.'

    Have you ever felt like you are not given the kind of respect you deserve? In one way or another, all of us have felt this way. We've yearned(渴望) to be looked at as an authority, someone people look up to and trust. We're not taught in school how to do this and our parents didn't tell us the secret on how to establish our authority. It's something we learn and gain by ourselves. And the answer is as simple as changing our mindset. What? No way! Oh but it is. People tend to underestimate the power of the mind. Change your game by changing your mind.

    Take time to look back and think about people in your life who are an authority or a leader at work, who has more credibility(可信度) than you or who you look up to and inspires you. They are up there not for the reasons you think. If you really think about it, they aren't the smartest of the bunch, not the most educated, and neither are they the best. And in no way do they even call themselves an expert. Instead, they are up there because they are great teachers and advocates(支持者) for the success of their customers or employees.

    Let's take Richard Simmons for example. This famous fitness personality has been a household name ever since he started gaining popularity during the first few years of his career. Stop and think, though, do you really think he is the best person to really get people into shape? Is he the Einstein of fitness and nutrition? Or does he even call himself a master of his craft? Of course not. People look up to him and give him authority because he is a great educator. Instead of sharing information that's far too complicated to understand, he figures out what your problems are and finds out a way to fix them. He even has social media that he updates on a regular basis with topics that are helpful and easy to understand for his fans and followers.

    Depending on the field you're in, you can share with people things you know and that you think they will want to know as well. If you're a nurse, for example, you can make a blog post for common health problems and quick remedies(治疗方法) people can do at home. Remember, the simpler you can make it, the better. People will trust you completely if you give them easy solutions. Like Richard, you'll soon be the expert you'll want to listen to. You can be an advocate also by showing people that you have their best interests at heart. You can also start up conferences to take up people's concerns and try to deal with them the best way that you can.

    So, how will you be viewed as an authority? Make that mind shift. Find out what concerns and troubles your target. Give solutions. Show that you care. And help them climb up that ladder of success. Ladies and gentlemen, that's how it's done.

    Adults understand what it feels like to be flooded with objects. Why do we often assume that more is more when it comes to kids and their belongings? The good news is that I can help my own kids learn earlier than I did how to live more with less.

    I found the pre-holidays a good time to encourage young children to donate less-used things, and it worked. Because of our efforts, our daughter Georgia did decide to donate a large bag of toys to a little girl whose mother was unable to pay for her holiday due to illness. She chose to sell a few larger objects that were less often used when we promised to put the money into her school fund(基金）(our kindergarten daughter is serious about becoming a doctor)

    For weeks, I've been thinking of bigger, deeper questions: How do we make it a habit for them? And how do we train ourselves to help them live with, need, and use less? Yesterday, I sat with my son, Shepherd, determined to test my own theory on this. I decided to play with him with only one toy for as long as it would keep his interest. I expected that one toy would keep his attention for about five minutes, ten minutes, max. I chose a red rubber ball-simple, universally available. We passed it, he tried to put it in his mouth, he tried bouncing it, rolling it, sitting on it, throwing it. It was totally, completely enough for him. Before I knew it an hour had passed and it was time to move on to lunch.

    We both became absorbed in the simplicity of playing together. He had my full attention and I had his. My little experiment to find joy in a single object worked for both of us.

    “Freelance retail consultant” refers to daigou in Chinese, or overseas people who buy goods for customers in the Chinese mainland.

     It's estimated that there are 40,000 daigou in Australia, most of whom are young migrants or international students looking for ways to help cover their rent and university cost.

    These freelance retail consultants have created thousands of trading routes, both small and big, into China.

    Shops in Australia sold out of instant formula （婴儿配方奶粉）, leaving many Australian parents unable to buy their preferred brands. The Sydney Morning Herald reported last year that half of Australia's infant formula sold went to China through customers selling to other customers.

    Because of this, daigou have received criticism from Australian media. The Sydney Morning Post even suggested that the Australian government should put a limit on instant formula exports.

    However, not everyone dislikes daigou. “We think daigou are good for the local economy and they are very good for our business,” Peter Nathan, the chief executive of A2 Milk, a New Zealand infant formula maker, told Reuters. “We clearly believe they are a positive force.”

    Others agree that nothing is wrong with the practice. “People are buying these products legally on the Australian market… they're not illegally being exported to China,” Tim Foulds, head of research at Euro monitor Australia and New Zealand, told The Washington Post.

    I have three kids and a great husband and I'm enjoying a career that I find challenging and fun. This feels like "Success" to the outside world. But there is still a voice in my heart asking if this is who I truly am. Only in silence do I hear the self and wonder who that person might be.

    So I booked a trip to find out. I travelled, for the first time, without my husband or kids. I went to Iceland with a friend, who shares an appreciation for wilderness and silence.

    For six days, we were immersed in wild, raw scenery and real weather—all kinds of weather. Climbing a mountain against rain and returning to a tent for a simple meal reminds you how little you actually need. And how strong it feels to be uncomfortable sometimes.

    I found silence in Iceland，and time to consider the me outside of career and the me outside of kids as I shared stories with strangers.

    When I stopped talking and just listened，I became more generous. I 1earned that choosing to be generous can create more space, more food and more warmth.

    But I didn't really gain any better appreciation of what I want from life or my job. I suspect the anxiety that drove me to seek silence in Iceland was losing sight of my ability to choose gratitude and joy，and to be present in the challenges I set in my career and my family.

    I came home to noise，rush and love; with no less confusion on who I want to be. I know the answer isn't waiting out there on the top of a mountain in Iceland. The answer is in front of me with every step on my own 1ife's path, and in every choice I make.

Throughout human history, there is a bottomless well of people who made great contributions so that we can now enjoy a better life. The following are, just four of those great minds.

Joseph Lister(1827—1912)

English surgeon(外科医生) Lister pioneered the use of antiseptic(防腐的)and antiseptic surgery which greatly improved survival rates from major surgery. For this, he is often referred to as the father of modern surgery as his use of antiseptic greatly increased the kinds of operations that could be carried out.

Maximilian Bircher-Benner(1867—1939)

Bircher-Benner was a pioneering Swiss physician and nutritionist. He advocated the eating of raw fruit and vegetables and discouraged eating meat and heavily processed foods. Although he was questioned by the scientific establishment, his healthy eating ideas took off and helped create a diet of processed bread, meat and carbs (碳水化合物). The healthy eating trends he established have continued to grow in popularity with more scientific research showing the health benefits of such a diet.

Paracelsus(1493—1541)

Swiss-German physician and leading health reformer. Paracelsus founded the discipline of toxicology(毒理学)and pioneered the use of chemicals in treating patients. He emphasized practical experience. He was also one of the first doctors to note illness can be psychological in nature.

Peter Mansfield(1933—2017)

English physicist who with Peter Lauterbur helped to develop magnetic resonance imaging(MRI)which gets doctors to see inside a patient's body without needing to cut it open. With MRI, doctors can see far more than with x-ray, which is limited to bones. He was awarded the Nobel Prize in Medicine in 2003.
