It seems the more time we have, the longer we put off living the life we see in our heads, because we feel like we've got some time to kill.

    I know where you think I'm going with this, and I also know you've heard it all before: seize the day, make the most of it, live life to its fullest, and so on. But that's the problem. You've heard it all before. These ideas have their impact and have become a cliché. Luckily, that's not my thing.

    The real answers wake something up inside you. They make you think. That's what I want to give you today, the story of Bobby Darin, which wakes you up to the truth.

    If you haven't heard of the man, I know you've heard his songs. Among his many hits are Mack the Knife, Beyond the Sea, Dream Lover, and Splish Splash.

    If seven years, Darin had several top ten hit songs, was nominated(提名) for four Grammy Awards (winning two), nominated for four Golden Globes (winning one), and even nominated for an Oscar.

    So what was his secret?

    All his life, Darin had a heart condition that developed from a childhood illness. The doctors at the time said he would be lucky to live to 16. In other words, his time was limited. And this was secret. He knew the truth. He knew that we all have such a hard time accepting: Life is short. You can't just say it; you can't just hear it. You have to know it, believe it, and feel it. Because Darin knew his time was limited, he packed as much life as he could into the time he had. But he had an unfair advantage. He knew, without a doubt, his time was limited.

    There was no fooling himself, no putting it off. It was now or never.

    Like many other people, I love my smart phone, which keeps me connected with the larger world that can go anywhere with me. I also love my laptop，because it holds all of my writing and thoughts. In spite of this love of technology, I know that there are times when I need to move away from these devices and truly communicate with others.

    On occasion, I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas. Because I want students to thoroughly study the materials and exchange their ideas with each other in the classroom, I have a rule —no laptop, iPads, phones, etc. When students were told my rule in advance of the class, some of them were not happy.

Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There's a bit of truth to that. Some students assume that I am anti-technology. There's no truth in that at all. I love technology and try to keep up with it, so I can relate to my students.

    The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly engage complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently and make connections between the course materials and the class discussion.

I've been teaching my history class in this way for many years and the evaluations reflect student satisfaction with the environment that I create. Students realize that with deep conversation and challenge, they learn at a level that helps them keep the course materials beyond the classroom.

I'm not saying that I won't ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I'm sticking to my plan. A few hours of technology-free dialogue is just too sweet to give up.

    Don't we all know a "Happy Meal" when we see one—the famous boxed meal that includes a hamburger, kid-sized French fries, fruits and milk, served with a toy that's extremely popular with children who love to collect them?

    A Happy Meal is a form of kids' meal sold at a certain fast-food chain since 1979. A toy is included in the meal, both of which are usually contained in a box or paper bag. However, collectors of these little toys will not get them any longer, since the company will replace toys with books and each of these books will mainly pass on nutritional messages.

    Happy Meals are extremely popular with kids, especially for their collectable toys, when you consider that over 1.3 billion of these packages are sold each year. These packages have been very controversial. Health supporters believe that drawing kids to these meals with toys is clever way of promoting unhealthy food choices. They see it as an advertising strategy of "catching its customers young"—a move that has paid off very well for the fast-food company.

    Child development experts say that food habits get formed in children by age six and continue through to their adult life. Fatty and sugary foods such as those served in Happy Meals are believed to play a big role in growing health problems such as obesity and diabetes. Public health care costs have gone up and untold amounts of money have been spent on coping with these health problems. On November 2, 2010, the San Francisco Board of Supervisors passed a law requiring that children's meals sold in restaurants must meet certain nutritional standards before they could be sold with toys, to overcome the problem of childhood obesity—in other words, the State of California tried to ban the toys in Happy Meals. However, it was strongly opposed by some as being heavy-handed, and the ban was thrown out by the government.

    While some people believe that the fast-food company, with its large following of children, can create a powerful message through the books, others believe its actions are contradictory. Anyway, the company is trying to spread the message of nutrition while it is serving food that is anything but healthy.

    According to the International Ecotourism Society, eco-travel is "responsible travel to natural areas that protects the environment, maintains the well-beings and involves education". Eco-travel is on the rise, as more and more people become conscious about their carbon footprint.

    Expert from Boundless Journeys, Matt Holmes, who works-on travel experiences towards conserving areas said, "As scientists and non-scientists learn more about how we human beings are impacting the planet, I think more people want to do what they can while still exploring the world. Our guests are definitely interested in that aspect of our journeys. Travelers can farm their own food in Italy, managing their use of water and using solar or wind power. They can also visit n family-run camp that cares for retired logging elephants in Myanmar, know a park entry fee goes to a conservation organization in Costa Rica, employ and train members of the local community or partner with a protection group. There are lots of options for seeking out greener holiday."

    Most people believe that eco-travel is expensive and it is true. Matt explained "Anti-poaching patrols (巡逻) need to be paid, solar energy equipment costs a lot to install, building with environmentally friendly, materials is more expensive and so on. The extra cost is necessary, as you're paying to minimize your footprint and protect the places you visit, which is exactly what eco-travel is about. The financial success and sustainability (可持续性) of an eco- focused operation doesn't come from thin air." The industry is trying to make eco-travel affordable and make it accessible to the common people.

    MacArthur's love for sailing dates back to when she was just four years of age, when she first got the opportunity to have a try. "I'll never forget that feeling as a kid of setting foot on a boat for the first time," MacArthur said. "It's kind of struck me that this boat had everything we needed to take us anywhere in the world. And as a child, that opened up everything," she explained how it felt like the "greatest sense of freedom".

    This experience lighted a passion within MacArthur. She knew then that she wanted to sail around the world. She had no idea how to achieve it — growing up in the countryside, it wasn't the most obvious career path — but she knew that was what she wanted to do at some stage. So, she acquired knowledge and saved up for years to seek a career in sailing. She would have potato and beans every day for eight years so that she could save up to buy the right equipment. By reaching certain financial goals and asking technical questions about sailing, MacArthur felt as though she was getting closer to her ambitions.

    "When you know where you're going, you can actually get there — even if it seems impossible. The impossible could be possible and aiming high is not necessarily such a crazy thing to do." And it seems that MacArthur's drive to become a sailor went beyond her expectations. At the age of 24, she started to receive media attention after participating in the Vendee Globe, a single-handed non-stop yacht (游艇) race that goes around the world. She came in second place. Some three to four years later, MacArthur chose to sail for 71 days and 14 hours, covering more than 26,000 miles during the course of her journey. This led to MacArthur scoring a new world record in 2005, as the fastest person to sail around the globe single-handedly. While this record has since been surpassed, MacArthur is still considered as Britain's most successful off shore racer.
