Recently my husband had his Achilles tendon（跟腱） cut when feeding a chicken. When sitting in the doctor's office waiting for surgery stressfully, I decided to treat myself for a minute and start to read about “The Little House on the Prairie”. Suddenly I felt my life seemed like a slack（懈怠） compared to the Ingalls who do all their washing and cooking but they feel so happy. Their every happiness is created from the work with their own hands. Yet I'm walking around feeling sorry for myself because I'm picking up the slack! So I'm thinking “Work it out! Get up and get busy.”

    It really is true. I realize that I'm happiest when accomplishing tangible(有形的) productive work—working in the yard and washing my dishes—brings me happiness. This does not surprise Kelly Lambert Ph.D. She has been researching the phenomenon she calls “effort-rewards”. When you do meaningful work with your hands, a kind of neurochemical feedback floods your brain with dopamine and serotonin. These happy brain chemicals are natural antidepressants, and we've evolved to release them both to reward ourselves for working with our hands and to motivate ourselves to do it some more. Dr. Lambert says Americans have become more depressed in recent years and at the same time we've experienced a decrease in purposeful physical activity. Did we lose something vital to our mental health when we started pushing buttons instead of ploughing the fields?

    Dr. Pansinski says she gets that happy look when she prepares a meal at the end of a day. “We are programmed to reward ourselves when we accomplish things with our hands. For so many people, it just feels as though everything's going so fast—life, kids, hundreds of e-mails a day. There is so little you can really see and hold on to. Working with one's hands is a way to slow down, to take pleasure in life again.”

With around 100 students scheduled to be in that 9:00 am Monday morning lecture, it is no surprise that almost 20 people actually make it to the class and only 10 of them are still awake after the first 15 minutes; it is not even a surprise that most of them are still in their pajama's(睡衣). Obviously, students are terrible at adjusting their sleep cycles to their daily schedule.

    All human beings possess a body clock. Along with other alerting systems, this governs the sleep/wake cycle and is therefore one of the main processes which govern sleep behaviour. Typically, the preferred sleep/wake cycle is delayed in adolescents, which leads to many students not feeling sleepy until much later in the evenings. This typical sleep pattern is usually referred to as the “night owl” schedule of sleep.

This is opposed to the “early bird” schedule, and is a kind of disorder where the individual tends to stay up much past midnight. Such a person has great difficulty in waking up in the mornings. Research suggests that night owls feel most alert and function best in the evenings and at night. Research findings have shown that about 20 percent of people can be classified as “night owls” and only 10 percent can be classified as “early birds” —— the other 70 percent are in the middle. Although this is clearly not true for all students, for the ones who are true night owls, this gives them an excellent excuse for missing their lectures which unfortunately fall before midday.

    For the business traveler who is all about efficiency: Check out these hotels that will get you in and out with a minimum of trouble. When you are pressed for time on a business trip, nothing can infuriate you more than a slow hotel check-in process. On your next trip, try these hotels that offer a speedier check-in process.

    ⒈ Yotel New York

    The self-service kiosks at this high-tech New York hotel work just like the ones you'd see at an airport. There are just five-steps to register and obtain your card key. There is even a robotic luggage bellboy. You tap in the number of bags you are carrying and sizes, then wait for a robot arm to swing down and store your luggage in a locker (say, for a day trip). This also speeds up the check-in process if the first thing you need to do, like me, is head to a series of meetings.

    ⒉ Marriott Detroit Airport

    Another option for business travelers in a hurry: Marriott is rolling out its mobile check-in app to 325 hotels this year, including the Marriott Detroit Airport hotel. (I've tested the app itself but not for a real visit quite yet.) Here is the basic idea: you download the iphone or Android app. The night before, you can “check-in” virtually. When you arrive, you get an alert that the room is ready and your key, which is already tied to your reservation, is waiting for you at the desk.

    ⒊ Hyatt Regency Minneapolis

    I happened to stay at this hotel recently and liked how fast the kiosk check-in works. Like the Yotel, the kiosk asks you to insert your credit card, similar to an airport terminal. The whole process took about three minutes, when I left, I was equally impressed with the fast check-out. An agent meets you in the lobby with an ipad and asks for an email to use for a receipt. The big advantage: you never have to wait in line.

    ⒋ Radisson: LaCrosse

    The Radisson is trying to make the kiosk process even faster, at a few select hotels like the Radisson Lacrosse in Wisconsin, you use a mobile app to register and then receive a barcode by email or text. When you get to the kiosk, you scan the barcode to get your key without any other steps required. It's super fast. You can find this new check-in system at the Radisson hotels in Salt Lake City, Seattle, and Phoenix as well.

    When your child lies to you, it hurts. As parents, it makes us angry and we take it personally. We feel like we can never trust our child again. Why does lying cause such anger, pain and worry for parents?

    Parents are understandably very afraid of their children getting hurt and getting into trouble, but they have very little protection against these things as they send their kids out into the word. Kids learn from other kids and from external media, and this makes parents feel unsafe because they can't control the information and ideas that their children are exposed to.

    When your kid lies, you start to see him as “sneaky（卑鄙的）”, especially if he continues to lie to you. You feel that he's going behind your back. You begin to think that your kids are “bad”. Because, certainly, if lying is bad, liars are bad. It's just that simple. Parents need to make their kids responsible for lying. But the mistake parents make is that they start to blame the kid for lying. It's considered immoral to lie. But when you look at your kid like he's a sneak, it's a slippery slope （滑坡谬误）that starts with “You lie” and ends up at “You're a bad person”.

    Kids know lying is forbidden. But they don't see it as hurtful. So a kid will say, “I know it's wrong that l eat a sugar snack when I'm not supposed to. But who does it hurt?” “I know it's wrong that I trade my dried fruit for a Twinkie. But it doesn't really hurt anybody. I can handle it. What's the big deal?” That's what the kid sees.

    So I think that parents have to assume that kids are going to tell them lies, because they're immature and they don't understand how hurtful these things are. They're all drawn to excitement, and they'll all have a tendency to distort（歪曲）the truth because they're kids.

    There are many places to go on safari in Africa, but riding a horse through the flooded waters of Botswana's Okavango Delta must rank as one of the world's most exciting wildlife journeys.

    Several safari camps operate as the base for this adventure, providing unique rides twice a day to explore deep into the delta. The camps have excellent horses, professional guides and lots of support workers. They have a reputation for providing a great riding experience.

    The morning ride, when the guides take you to beautiful, shallow lakes full of water lilies, tends to be more active. It is unlike any other riding experience. With rainbows forming in the splashing water around you and the sound of huge drops of water bouncing off your body and face. It is truly exciting. You are very likely to come across large wild animals, too. On horseback it is possible to get quite close to elephants, giraffes and many other animals. The sense of excitement and tension levels rise suddenly though, as does your heart rate, as you move closer to them.

    In the evening, rides are usually at a more relaxed and unhurried pace. With golden light streaming across the grassy delta and the animals coming out to eat and drink. Sedate though they are, rides at this time of day are still very impressive. As the sun's rays pass through the dust kicked up by the horses, the romance of Africa comes to life.

    Back at the camp you can kick off your boots and enjoy excellent food and wine. Looking back on your day, you will find it hard to deny that a horseback Safari is as close as you will ever come to answering the call of the wild.
