Over 40 years ago, a country music DJ convention (大会) was held every year in Nashville, Tennessee. Many country performers used to attend (参加) the convention to give their performances. Fans would go to Nashville hoping to see their favorite performers. In the end, so many fans began showing up in Nashville that a festival named Fan Fair was born.

    The first Fan Fair was held in April 1972, in Nashville for four days. Some of country music's biggest stars attended. There were about fifty thousand fans. The first Fan Fair was so successful that planning began almost immediately for 1973. The date was changed to June, when the weather would be better. Over one hundred thousand fans attended the second Fan Fair.

    Every year brought so many performers and fans to Fan Fair that, in 1982, it was moved to the Tennessee State Fairgrounds. Fan Fair stayed at the fairgrounds for another nineteen years.

    There was always the unexpected during the festival. In 1974, former Beatle Paul McCartney attended. In 1992, more than six hundred reporters from Europe, Asia, and South America went to cover the appearance of a popular star, Billy Ray Cyrus, who had introduced a new country line dance. In 1996, Garth Brooks, who made a surprise appearance, signed autographs (签名) for 23 hours.

    In 2001, Fan Fair returned to downtown Nashville as the world's biggest country music festival. Now, over one hundred and twenty-five thousand country music fans go to Nashville every June. As you can imagine, those who want to attend Fan Fair must plan ahead. For example, they need to buy a ticket several months ahead of time. Of course, there's much more to prepare.

    Our local Community Youth Club is a very popular organization with young people in my town. I have been a member for four years now and I've taken part in a lot of interesting projects. These include fun activities such as holiday camps and discos. We have organized sports competitions and we even made a video.

    But it isn't all just enjoyment, we have also started doing social work to help people in our neighbourhood. We have organized activities for small children during the holidays. We have also formed a social support group to help young people stop smoking.

    We are particularly proud of the most recent group we have created. It organizes regular visits to the local old people's home. This idea came from a school visit to an old people' home. My class spent an afternoon at a home and everyone found the visit very rewarding.

    The old people at the home were very excited by our visit. They were very talkative(健谈的) and they told us their personal stories. During our visit, the home was filled with the sound of laughter. We sang songs and played games with the old people and had tea together. But we realized that life wasn't always easy. Some of them were in poor health and were very unhappy. They couldn't go outside the visits by children brought some sunshine into their lives.

    Many young people like me do not live with our grandparents and we have very little contact with elderly people. As a result, many young people don't know what they are like and we have a lot of wrong ideas about them. We have little or no idea of the kind of lives they lead in their homes. After this visit, my friends and I decided we should do something to help improve the quality of their lives.

    Since the creation of our visiting group, over twenty volunteers(志愿者) have joined us. Up to now, we have organized three group evenings and a concert. But it is the individual(单独的) visits which are the most important. Club members regularly visit old people and everyone finds the experience rich and rewarding.

    Technology is always trying to meet our needs and demands. There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook and serve foods on a mass scale. And the industry isn't stopping there.

    Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "recreate forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Sustainability (可持续性)

    The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae (藻类) and grass to replace the familiar ingredients (烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

    Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    Challenges

    Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste (糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurant than homes and high-end restaurants.

    When I started working, I couldn't understand why there were some people who seemed to succeed in anything they tried, while there were others who just couldn't manage to achieve anything. After a while, I became amazed at the biggest difference lying in setting and reviewing goals regularly.

    Then I saw an academic study done by Dr. David Kohl on goals:

    80% of Americans claim that they don't have goals.

    16% of them have goals, but they don't write them down.

    Only 3% actually have written goals, but they don't review them regularly.

    Only 1% has written goals and they review them regularly, and these are among the highest achievers in the US.

    You need to set goals, independent of whether you want to achieve more or less. Goals are not only about achieving more or wanting to take on more in life-a goal starts with a simple desire.

    What do you do with your desires and wants in life? You could both ignore them and leave them to fade away in your mind, or listen to yourself and start taking action to get what you want in life.

    On the one hand, you can wish for a miracle, try to put the least amount of effort in, hoping to get the most out, and do nothing. On the other hand, you can get clear on the steps you need to take and take them, slowly, one by one until you reach success in that area and you will live with new amazing results in your life.

    Setting goals is the essential part to achieving success in any area. It begins with a desire, and then a written goal, followed by the right attitude and action, and that is your formula for success. Keep reviewing your goals and watch how your vision turns into your reality.

    I'm a speaker and give hundreds of speeches every year. I spoke about appreciation (感激) last month and I used this quote by Albert Schweitzer "Sometimes our light goes out but is blown again into flame by meeting with another human being. Each of us should express the deepest thanks to those who have relighted this inner (内心的) light."

    I asked my audiences to shut their eyes and think about someone who, at some time in their lives, has relighted their inner light. Then I left the room in silence for several minutes. It was always a meaningful experience as they remembered the joy they felt from another person.

    One day, a gentleman came up to talk with me and thanked me for creating a new awareness (意识) in him. He said he thought of his eighth-grade history teacher because she was everyone's favorite teacher and had really made a difference in all of their lives. Several days later, the gentleman found his history teacher and he wrote to her. The following week he received this letter:

    Dear John,

    You will never know how much your letter meant to me. I am 83 years old, and I am living all alone in one room. My friends are all gone. My family's gone. I taught 50 years and yours is the first "thank you" letter I have ever gotten from a student. Sometimes I wonder what I did with my life. I will read and reread your letter until the day I die.

    The gentleman was sad, "She is always the one we talk about when we have a get-together. She is everyone's favorite teacher—we love her! But no one had ever told her until she received my letter…"

Video calls are a common occurrence, but have you imagined being able to touch the person on the other end of the line? Scientists are making this a reality.

Researchers at the University of New South Wales, Australia, have invented a soft skin stretch device (SSD), a haptic device that can recreate the sense of touch. Haptic technology can mimic the experience of touch by stimulating localized areas of the skin in ways that are similar to what is felt in the real world, through force, vibration or motion.

Vibration is the most common haptic technology today and has been built into many electronic devices, such as one attached to the back of a trackpad in laptops. However, haptic feedback with vibration becomes less sensitive when used continuously. The existing technology also has great difficulty recreating the sense of touch with objects in virtual environments or located remotely.

The new technology overcomes issues with existing haptic devices. The research team introduced a novel method to recreate the sense of touch through soft, artificial "muscles".

It works like this: imagine you call a friend in Australia. You wear a haptic glove with the SSDs and your friend also wears a glove with 3D force sensors. If your friend picks up an object, it will physically press against your friend's fingers. And the glove with 3D force sensors will measure these interactions. The force signals can be sent to your glove so your device will generate the same 3D forces, making you experience the same sense of touch as your friend.

The haptic devices could be used in various fields, allowing users to feel objects inside a virtual world or at a distance. This could be especially beneficial during such times like the COVID-19 pandemic when people rely on video calls to stay connected with loved ones. Or it could be used in medical practices. Doctors can feel a patient's organ tissues without touching them.
