Drinking more than two alcoholic drinks daily in middle-age may raise your stroke(中风) risk more than traditional factors such as high blood pressure and diabetes（糖尿病）, according to new research in the American Heart Association journal Stroke.

    In a study of 11,644 middle-aged Swedish twins who were followed for 43 years, researchers compared the effects of an average of more than two drinks daily ("heavy drinking") to less than half a drink daily ("light drinking").

The study showed that:

·Heavy drinkers had about a 34 percent higher risk of stroke compared to light drinkers.

·Mid-life heavy drinkers (in their 50s and 60s) were likely to have a stroke five years earlier in life irrespective of genetic and early-life factors.

·Heavy drinkers had increased stroke risk in their mid-life compared to well-known risk factors like high blood pressure and diabetes.

·At around age 75, blood pressure and diabetes appeared to take over as one of the main influences on having a stroke.

Past studies have shown that alcohol affects stroke risk, but this is the first study to pinpoint differences with age. "We now have a clearer picture about these risk factors—-how they change with age and how the influence of drinking alcohol shifts as we get older," said Pavla Kadlecová, M.Sc., a statistician at St. Anne's University Hospital's International Clinical Research Center in the Czech Republic.

    Researchers analyzed results from the Swedish Twin Registry of same-sex twins who answered questionnaires in 1967-1970. All twins were under age 60 at the start. By 2010, the Registry had provided 43 years of follow-up, including hospital discharge(出院) and cause of death data.

    Researchers then sorted(整理) the data based on strokes, high blood pressure, diabetes and other cardiovascular (心血管)incidents. Almost 30 percent of participants had a stroke. They were categorized(将……分类) as light, moderate, heavy or non-drinkers based on the questionnaires. Researchers compared the risk from drinking and health risks like high blood pressure, diabetes and smoking. Among identical twin pairs, siblings(兄弟姐妹) who had a stroke drank more than their siblings who hadn't had a stroke, suggesting that mid-life drinking raises stroke risks regardless of genetics and early lifestyle.

    The study is consistent (一致)with the American Heart Association's recommended limit of two drinks a day for men and one for women. That's about 8 ounces of wine for a man and 4 ounces for a woman.

    Regular heavy drinking of any kind of alcohol can raise blood pressure and cause heart failure or irregular heartbeats over time, in addition to stroke and other risks. "For mid-aged adults, avoiding more than two drinks a day could be a way to prevent stroke in later productive age ," Kadlecová said.

    Earthquakes happen without warning(前兆). They can happen any time of a day, at any point during the year. But don't worry because most are so weak that they cannot be felt. Only a few big ones hurt people. However, it's important to know what to do when an earthquake is happening.

    Do NOT go outside. You could get injured from falling glass or parts of buildings. If you are outside, stay away from buildings and power lines (输电线).

    Stay under a desk, table, or other strong furniture. Hold on to it. Or stay in a corner of the building. Cover your face and head with your arms and cover your mouth with a towel or clothing. Stay inside until shaking stops and it is safe to go outside.

    Keep away from windows, pictures or advertisements on the wall or the building, and anything else that could fall and hurt you. Most people get injured by falling things during an earthquake, not by the shaking itself.

    Also keep away from a fire. You could fall down and burn yourself on the fire.

    If you are driving when an earthquake happens, stop the car if it's safe. Stay inside your car until the earthquake stops, and don't drive near bridges. Try not to stop by power lines or trees. These could fall and hurt you.

    Shot in more than 40 locations in L.A., the musical La La Land is "a love letter to the city". To coincide with UK release, we asked a local writer to pick some of the film's amazing settings.

    Judge Harry Pregerson Interchange

    La La Land's opening scene is a six-minute dance that plays out in L.A.'s bad traffic. It is also where the film's leading roles, struggling actress Mia and jazz pianist Sebastian, first encounter each other—in a road anger incident. The scene is said to have been filmed over two hot days in south L.A.

    Smokehouse Restaurant, Burbank

This is the setting for the scene in which Mia discovers Sebastian's talent for the piano. The fictional Lipton's restaurant—where jazz purist Sebastian was reluctant to play Christmas music—is in reality a place long frequented by actors, producers and other show business types. It has been on this spot, across the street from the Warner Bros studio, since 1949. In the film, the outer wall of Lipton's is the You are the Star mural (壁画), which features Marilyn Monroe, Charlie Chaplin and others, which is on the corner of Hollywood Boulevard and Wicox Avenue in Hollywood in reality.

    Warner Bros Studios, Burbank

    Mia works at the studio's coffee shop, where Sebastian comes to meet her. As they wander the studio's lot, Mia points out "the window that Humphrey Bogart and Ingrid Bergman looked out in Casablanca." It's one of the film's numerous nods to movie history. Warner Brons is still a working studio, with 35 sound stages, 14 exterior sets and visitor tours.

    Cathy's Corner, Mount Hollywood Drive

    This section of the road that winds through Griffth Park is the setting of their dance play. It overlooks the San Fernando Valley and features on the film poster. Cathy's Corner is near famed Mulholland Drive, but prepare for disappointment if you're expecting a park bench and street lamps, which only exist in the movie.

Inventor James West was born in 1931 in Virginia. As a child, he spent lots of time studying how things worked and enjoyed taking apart small machines. "If I had some tools, any small machines that could be opened were in danger," West said. "I had a strong desire to know what was inside. "

After an accident with a radio, West paid special attention to electricity. But his parents were concerned about the future job for an African-American scientist. They preferred him to become a doctor. However, West headed to Temple University in 1953 to study physics. Because of his school performance in physics, he managed to get training during the summer at Nokia Bell Labs, a world-known American industrial research and scientific development company. He received a college degree in physics in 1957, and upon graduation, he became a worker at Nokia Bell Labs.

In 1960, while at Bell, West teamed up with scientist Sessler to develop a less expensive, more powerful and smaller microphone (麦克风), In 1962, they finished the development on the product. Their invention became the industry standard. And even today, 90 percent of microphones — for example, found in telephones, tape recorders, baby monitors and hearing aids — are based on their technology.

West was chosen as Inventor of the Year by the state of New Jersey and president of the Acoustical Society of America. And both West and Sessler were chosen into the National Inventors Hall of Fame.

West left Bell in 2001. After some interviews with several universities, he chose the Johns Hopkins University and became a research professor at its Whiting School of Engineering. "I discovered that Johns Hopkins was a lot like Bell Labs, where the doors were always open and we were free to work with researchers in other areas," he said. "I like the fact that I won't be locked into one small closed room here. "

I was interested in volunteering at a hospital because both of my parents work in hospitals. I wanted to see what the 1 was after hearing them talk about it. To be more 2 , I wanted to work at the VA — a hospital in Palo Alto because the 3 of VA is "to serve those who served" and I really 4 this very idea.

To my greatest joy, I was 5 the VA program, and throughout this summer break I've spent around 110 hours 6 at VA Palo Alto in different departments. To be honest, I had never at all felt more welcomed and 7 in every department I went to. After some initial experiences, I 8 to work in the Office of Information Technology (OIT) since I am interested in computers, and I wanted to see how they are used in a hospital setting.

My overall experience of volunteering at VA can be 9 into the words of "eye-opening and 10 ." Throughout my whole life I have been 11 to health care from both my parents being physicians and my health problems, but I have never 12 been on the other side of the glass, so to speak. What I 13 most about my experience was the ability to see what it's like to help people. I want to 14 volunteering at VA because I believe there is no other experience that can be as 15 as working in a hospital that treats Veterans.
