People with an impulsive personality refer to those who tend to do things without considering the possible dangers or problems first. According to a new study by researchers at the University of Georgia, such people may be more likely to have food addiction. The study found that people exhibiting impulsive behavior weren't necessarily overweight, but impulsiveness was related to a direct relationship with food, and therefore, less healthy weight.

    Food addiction has been compared to addictive drug use. Studies have linked the dopamine (多巴胺) release that occurs after tasting delicious food to the dopamine release that happens when people consume other addictive substances.

    Impulsive behavior involves several personality traits (特点). Two of these traits, known as negative urgency and lack of perseverance, were particularly associated with food addiction and high BMI (身体质量指数) during the study.

    Negative urgency is characterized by the tendency to behave impulsively when experiencing negative emotions. Some people might drink alcohol or take drugs. For others, it could mean eating to feel better. Lack of perseverance is when a person has a hard time finishing hard or boring tasks. People with a lack of perseverance might have difficulty attempting to change addictive eating behavior, which could also cause obesity.

    “Impulsiveness might be one reason why some people eat in an addictive way despite motivation to lose weight,” said Dr. Ashley Gearhardt, a clinical psychologist. He was involved in developing the Yale Food Addiction Scale in aid of those people. “We are theorizing that if food addiction is really a thing, then our measure, the Yale Food Addiction Scale, should be related to helping control impulsive action,” said Gearhardt.

    Clinical psychologist Dr. James MacKillop, whose lab was conducting the study, believes that therapies used to treat addictive drug behavior could help people who suffer from addictive eating habits.

    “Most of the programs for weight loss at this point focus on the most obvious things, which are clearly diet and exercise,” MacKillop said. “It seems that managing strong desires to eat would naturally fit in with the skills a person would need to eat healthily.”

    Imagine one day, the water taps in your house stop running. You have to buy water from shops. And still there isn't enough for everyone. Your mother has to save the family's shower water to do other things. Would you be able to stand that kind of life?

    Probably not. But that's what kids in Yemen are experiencing. Experts said Yemen is going to be the first country in the world to run out of water. According to a report, the capital, Sanaa, will run out of drinking water as early as 2025.

    Because of the shortage, the government often cuts the water supply. Hannan, 18-year-old from Lahej, told the Times: “In a good week, we'll have a water supply all week. But then the following week there will be water only for a day or two.”

    Hannan said only rich people have enough water to use. They can buy water from the shops or from the water truck. Private companies own the trucks. They travel around the city every day to sell water-at very high prices.

    “A lot of people can't afford it,” she said. The average person in Yemen uses 100 to 200 cubic meters of water per year. That is far below the international water poverty line of 1,000 cubic meters.

    The government is thinking of making use of seawater. But it will cost a lot and it may not happen soon enough to help the people of Yemen.

    If a trip to Rome or Paris is in your future, be prepared: The European Union Parliament is calling for an end to visa-free travel Americans. EU lawmakers passed a resolution urging the EU Commission to impose visas on U. S. citizens traveling into the 28-nation bloc.

    The dispute(争论)centers on reciprocal treatment of travelers from EU nations and the United States. While Americans have been able to travel throughout EU member nations without a visa, the U. S. still requires citizens of five EU countries-Bulgaria, Croatia, Cyprus, Poland and Romania-to apply for entry visas when visiting the U. S, Reuters reports. Citizens of the other 23 EU member nations can use the U. S. visa waiver program to enter America. The EU lawmakers are calling for mutual treatment for all EU citizens, says Reuters. They've given the EU Commission two months to respond.

    The trans-Atlantic visa dispute first came to light in April 2014, according to an EU Parliament news release. At that time, five countries-Australia, Brunei, Canada, Japan and the U. S. –required visas for some EU citizens. Since then, Australia, Brunei and Japan have lifted their visa requirements for all EU citizens. Canada, which currently imposes(推行)visa requirements on Bulgarian and Romanian citizens, plans to follow suit in next December, leaving just the United States at odds with the issue of reciprocity of visa-free travel with the EU.

The EU says if a visa requirement for Americans is introduced, it would be temporary, according to a story in Money, which did not give a time frame.

    When I was sixteen years old, I made my first visit to the United States. It wasn't the first time I had been abroad. Like most English children I learned French at school. And I had often been to France, so I was used to speaking a foreign language to people who didn't understand English. But when I went to America I was really looking forward to having a nice easy holiday without any language problems.

How wrong I was! The misunderstandings began at the airport. I was looking for a public telephone to give my American friend Danny a call and tell her that I had arrived. A friendly old man saw me looking lost and asked if he could help me.

    “Yes,” I said, “I want to give my friend a ring.”

    “Well, that's nice,” he said, “Are you getting married? But aren't you a bit young?”

    “Who is talking about marriage?” I replied, “I only want to give my friend a ring to tell her I've arrived. Can you tell me where there's a phone box?”

    “Oh!” he said, “There's a phone downstairs.”

    When at last we met, Danny explained the misunderstandings to me.

    “Don't worry,” she said to me. "I had so many difficulties at first. There are lots of words which the Americans use differently in meaning from the British. You'll soon get used to all the funny things they say. Most of the time, British and American people understand each other!”

    Everyone should be so lucky as to have a friend like Francia Raisa. On Thursday, singer and actress Selena Gomez, 25, used Instagram to explain why she was "laying low" this summer. She posted a photo of herself in a hospital bed with her friend Francia Raisa holding hands. She said she recently received a kidney transplant from her best friend because of complications(并发症) from lupus(狼疮), an autoimmune disease, which means it is the result of the immune system attacking normal tissue, including the kidneys, brain, heart and lungs.

    People with lupus may first experience tiredness, joint pain or a little bit of rash(皮疹) on their bodies and can go for a long time before their doctors realize it is more serious. Many people see two or four doctors before the real problem is picked up. According to Dr. Kyriakos Kirou, roughly a third to one-half of people with lupus develop kidney disease, and up to one in five of them will eventually need a transplant, sometimes because they weren't treated with effective drugs to prevent the immune system from attacking the kidneys. Though Gomez said that she was "very well now," she warned about the dangers of not taking medical diagnoses seriously, like she initially did.

    Her Instagram post also called attention to two major health topics: the need for living organ donators and the fact that Gomez represents three groups more likely to be diagnosed with lupus and lupus-related kidney disease. Nine out of 10 people diagnosed with lupus are women, and most develop the disease between the ages of 15 to 44. And lupus is two to three times more common among women of color, including Hispanic women, according to the Lupus Foundation.

    Raisa is Latina, and Gomez's father is of Mexican origin. While it's not essential that the organ donator and receiver be of the same ethnicity, people who share a similar background sometimes are better matched, according to data from the United Network for Organ Sharing.
