A culture's values can be mirrored by its humor. Humor has been evaluated by many great minds such as Thomas Hobbes, who, In"On Nature", disliked humor," Laughter is nothing else but sudden glory arising from sudden thought of feeling far better than others." He thought humor to be a negative quality of human narrow-mindedness.

    However, Mordechai Gordon, PhD of Education, insists," Humor allows us to view the world from an angle that is amusing rather than serious." I agree with Gordon. Learning to look at the world through humor is important.

    In the United States, every four years an election occurs. Without humor as a way to express their feelings, how would Americans be willing to support the election? Television shows like "The Daily Show" have become important parts of American culture. They are mothering the masses by unconsciously inputting politics into our mouths. They make politics fun.

    Of course, politics is only one type of humor. Social humor helps people through the twists and turns of the human condition. American pop culture promotes an unhealthy self image. On the topic of self-image, Hari Kondabolu stands out. He has a joke about the popular musical group "The Pussycat Dolls", describing their hit song "Don't Cha" as a negative representation of women. He points out an obvious offence in American culture.

    A study from Loyola University of Maryland has shown that humor is one determining factor for selecting a mating partner. Amongst other things, mates look for an outstanding funny bone in a potential partner.

    Of course, humor is not always used for good purposes. Humor can be linked to vulgarity（粗俗）and racism, but, like everything else, it has potential to unite human beings by allowing us to laugh at ourselves, our failures and our connection with one another.

    Though life may seem tough and depressing at times, all I have to do is look in the mirror at my increased wrinkles（皱纹）to know that there is a comedy out there that even Chaplin wasn't aware of.

    With that in mind, remember to laugh with humanity and sometimes at humanity.

    A heartbroken dog whose owner died two months ago is missing her so much that he attends services every day at the Italian church where her funeral was held, patiently waiting for her to return.

    Tommy, a seven-year-old dog, belonged to Maria Lochi, 57, and had been her faithful partner after she adopted him when she found him in fields close to her home. Mrs. Lochi adopted several dogs she found but friends said she developed a close friendship with Tommy and would walk to church with him every day, where he would be allowed to sit patiently by her feet.

    Father Panna said, “He's there every time I celebrate Mass and is very well behaved. He doesn't make a sound, and I've not heard one bark from him in all the time he has been in. He used to come with Maria and he was obviously devoted to her. I let him stay inside as he was always so well behaved and none of the other people ever complained to me. He's still coming to Mass even after Maria's funeral, he just sat there quietly. I didn't have the heart to throw him out. I've just recently lost my own dog so I leave him there until Mass finishes and then I let him out.”

    Tommy's been adopted by everyone in the village now and he is everybody's friend. Everyone looks out for him and leaves food for him, although it would be nice to find a proper home for him.

    The story of Tommy is similar to the 2009 Hollywood film Hachi which told of how a faithful Akita dog waits patiently for his master after he also dies. It was based on the true story of a Japanese Akita called Hachi, whose owner died in 1925 but for the next nine years he waited patiently at the railway station for his owner from where they regularly caught a train.

    Standing desks have become common across Silicon Valley, offering health benefits to those willing to work on their feet. However, due to their high price, they have failed to catch on until now. Recently, Ikea has brought out Bekant convertible（可变换的） standing desk that can become a normal desk at the touch of a button. The $500 adjustable desk can transform from a standard desk to a standing one, and Ikea hopes it could make the standing desk mainstream.

    Experts say that changing from a seated to a standing desk can improve productivity. Similar desks have become a common sight at tech firms such as Google, where some employees have even installed treadmill (跑步机) and bicycle desks.

    The desk is not the first “convertible” on the market. As early as 2013, Stir Kinect brought out an adjustable desk. The $3,890 Stir Kinect desk has a motor to raise and lower itself, changing it into a standing desk or a traditional desk. The desk can even be programmed to move up and down slightly, making it appear to take a gentle breath to remind the user to change their positions. To move between sitting and standing positions, owners simply double tap on the screen. The desk can learn the user's preferences over time and suggest the best seating position.

The Stir Kinect desk was created by a team of ex-Apple and Disney engineers. It has a built-in touch screen to control and track movement, and can tell users exactly how many calories they burn by standing during their working day. It also has devices containing power points and USB ports for charging phones, to keep cables hidden.

    “Ikea's height-adjustable desk is great for opening up the lower end of the market, " said JP Labrosse, founder and CEO of Stir.

    Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”. Now they should bite their tongues! Evidence is showing that some kinds of chocolate are actually good for you in the following ways:

    A happier heart

    Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow. These benefits are the result of coca's chemicals, which seem to prevent both cell damage and inflammation (炎症)．

    Better blood pressure

    If yours is high, chocolate may help. Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly.

    Muscle magic

    Chocolate milk may help you recover after a hard workout (锻炼). In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks.

    Better for your skin

    German researchers gave 24 women a half-cup of special cocoa every day. After three months, the women's skin was moister (滑润的) and smoother. The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．

Brain gains

    It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain．

    Earthquake rescue robots have experienced their final tests in Beijing. Their designers say that with these robots, rescue workers will be able to have more time to save more lives during an earthquake.

    This robot looking like a helicopter（直升机）, is called the detector-bot . It's about 4 meters long, and it took about 4 years to develop the model. Its main functions（作用）are to collect information from the air, and send goods of up to 30kilos, to people stuck in an earthquake.

    This robot has a high quality 360 degree panoramic camera. It can work day and night and will also be able to send the latest pictures from the quake area. Dr. Qi Juntong, Chinese Academy of Science, said, "Unlike other automatic machines, the most important feature of this robot is that it doesn't need a distant control. We just set the information of the earthquake-struck area on it, and then it takes off, and lands by itself. It flies as high as 3,000 meters, and as fast as 100 kilometers per hour. "

This robot has a different function — it can change as the environment changes. Its main job is to search for any signs of life in places where human rescuers are unable to go.

    As well as a detector（探测器）that finds victims（遇难者）and detects poisonous gas, a camera is placed in the 40 centimeter long robot, which can work in the dark.

    Another use for the rescuers is the supply bot, with its 10-meter-long pipe. People who are caught in the ruins will be able to get supplies including oxygen and liquids.

    Experts have said that the robots will enter production, and serve as part of the national earth- quake rescue team as soon as next year.

    It doesn't matter when or how much a person sleeps, but everyone needs some rest to stay alive. That's what all doctors thought, until they heard about AI Herpin. AI Herpin, it was said, never slept, Could this be true? The doctors decided to see this strange man themselves.

    AI Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw Herpin sleeping, In fact, he did not even own a bed. He never needed one.

    The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They found only one answer that might explain his condition. Herpin remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason? No one could be sure.

    Herpin died at the age of 94.
