As a little child, I was always plump（胖的）. In college I started blowing up. It got out of control when l went to law school.

    I'd made a decision a thousand times: I'm going to lose weight now. But what motivated（激发） me to get serious about it was turning 30.1 weighed 414 pounds.1 was always tired. Some of my family members have suffered from heart disease, and l was frightened. I also wanted to look better.

    So after my birthday, I walked into the office of a weight loss doctor.

    She was very understanding. Her focus was on balanced meals and she wanted me to exercise.

    Walking was all I could do at first. I started by walking a few blocks and gradually increased the distance, until one weekend, I heard myself saying, "Wow, this seems pretty easy." So I started to run.

    I was losing nine or ten pounds a month, and I had more energy. I started to think about the New York City Marathon. For years, I watched the runners and thought, "This looks like fun, but I could never do that." But now I realized that maybe I could. I joined the New York Road Runners. I ran a 10km, then a half marathon.I still wasn't confident I could run a full 26 miles. But I told myself I was going to do it, no matter what.

    By my 33rd birthday, I was down to 180 pounds. I started formally training for the marathon.

    And on the morning of November l, I stood on the Verrazano Bridge in Staten Island with more than 40,000 0ther runners, waiting for the event to start.

    It was unbelievable to have the audience cheering me on, handing me cups of water. And I crossed the finish line. My friends sprayed（向……喷射）me with beer, as if I'd won the Super Bowl.

    And at that moment, I knew: If I set my mind to something, nothing is impossible.

    CHICAGO(Reuters)－Smoking not only can wrinkle (皱纹) the face and turn it yellow—it can do the same to the whole body, researchers reported on Monday.

    The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body－even skin protected from the sun.

    "We examined non-facial skin that was protected from the sun, and found that the total number of packs of cigarette smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr. Yolanda, who led the study, said in a statement.

    "In participants older than 65 years, smokers had significantly more wrinkling than nonsmokers. Similar findings were seen in participants aged 45 to 65 years." Yolanda's team added in their report.

    The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged, in age from 22 to 91 and half were smokers. Independent judges decided how wrinkled each person's skin was.

    When skin is exposed to sunlight, especially the face, it becomes coarse(粗糙的), wrinkled and discolored with a pale yellow color, Yolanda's team wrote.

    Several previous studies have found that cigarette smoking led to premature(过早的)skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light.

    The previous research has found that cigarette smoke, among other things, causes blood vessels(血管)beneath the skin to constrict(紧缩), reducing blood supply to the skin.

    Smoking can also damage the connective tissue(组织)that supports both die skin and the internal organs (器官).

    At the age of seven, while his friends were spending their allowances on candy and toys, Jose Adolfo Quisocola, from Peru, came up with the creative idea of an eco-bank, which allows kids of all ages to become economically independent and financially wise while also helping the environment.

    Established in 2012, The Bartselana Student Bank is the world's first cooperative bank for kids. Whoever wants to join has to bring in at least 5 kilograms(11 pounds)of solid waste(paper or plastic)and establish a savings goal. Once accepted, all bank "partners" are required to deposit at least one additional kilogram(2.2 pounds)of recyclables on a monthly basis and obey other requirements, such as attending financial education and environmental management workshops. The waste accumulated is sold to local recycling companies, who, thanks to some clever negotiation by Jose, pay a higher-than-market rate for everything brought in by Bartselana Student Bank members. The funds received are placed in the individual's account where they collect until his／her savings goal is reached. The account holder can then withdraw his／her money, or choose to leave it and continue to grow for a bigger target.

    "At the beginning, my teachers thought I was crazy or that a child could not undertake this type of project," Jose recalls." They did not understand that we are not the future of the country but its present. Luckily, I had the support of the school principal and an assistant in my classroom."

    The youngster's persistence paid off. Today, the eco-bank, which now has the support of several local institutions, has ten educational centers and begins accepting applications from kids all across Peru. On November 20, 2018, the young boy was awarded the famous Children's Climate Prize (CCP)."Jose's eco-bank is a brilliant way of linking economy and climate impact, both in thought and practice. The potential impact is amazing," a judge said.

    Hopefully, Jose's success will inspire more kids and adults to come up with new ideas that create value while helping the environment. As the boy says," Together we can change the world…we just need an opportune it."

    Sitting has been called the new smoking for its supposed Public health risks, especially for people with sitting down office jobs. Over the past 15 years or so sitting has been connected with heart disease and diabetes (糖尿病). But is sitting really that risky?

    In our latest study we examined if not only the total amount of sitting, but different types of sitting, were connected with developing type 2 diabetes. We wanted to see if there was any difference among sitting watching TV, sitting at work, or sitting at home but not watching TV.

    We studied sitting habits of 4. 811 middle-aged people, who didn't have diabetes or heart problems at the start of the study. Over the next 13 years, 402 people developed diabetes. Once we considered obesity (AE RF), Physical activity, and other things that may develop type 2 diabetes, neither total sitting time, sitting at work nor sitting at home but not watching TV were connected with developing diabetes. We found only a weak connection with the time spent sitting watching TV and an increased risk of developing diabetes.

    This is different from the results of five older TV studies that showed a stronger connection. But hardly any of the included studies mentioned obesity, a major cause of diabetes.

    For people who are physically inactive, though, the story's different. Two recent studies show the total time spent sitting a day is connected with developing diabetes, but only in people who are physically inactive or both physically inactive and obese.

    That's not the whole story. At least two things determine if sitting is a risk factor in its own right: the type and situation of sitting.

    For example, sitting down at work isn't strongly connected with long-term health risks, Perhaps that's because higher position jobs needs more sitting, and higher socioeconomic (社会经济) position is connected with a lower risk of disease. It's a different case for sitting watching TV, the type of sitting most possibly connected with long-term health risks. People who watch a lot of TV tend to (a) be of lower socioeconomic positions, unemployed, have poorer mental (精神上的) health, eat unhealthy foods and face more unhealthy food advertising.

    A person can use all five senses while spending time with dolphins. We can see them play in the waves, hear them call, and feel their skin. Dolphins can sense you, too, but not in all the same ways. They have good eyesight, for example, but no sense of smell. Sensory biologists try to understand connections between animal behaviors and the senses. One team of these scientists recently made an unexpected discovery about certain dolphins.

    The researchers found that Guiana dolphins can detect electric fields, an ability that may help them find fish to eat. The secret to this newly found sense, say the scientists, is hidden in the dolphins' snouts (口鼻部).

    "We were really surprised to find this in the dolphin. Nobody had expected it," said Wolf Hanke, who led the new dolphin study.

    Hanke and his team suspected the dolphin's electro－sense might have something to do with small dimples (酒窝) on the animal's snout. "We thought they must have some functions," Hank said. To find out for certain, his team studied two Guiana dolphins.

    The scientists first studied the dimples of a 29－year－old dolphin that had died of natural causes. Under a microscope, the dimples looked familiar: they were similar to the sensors used by other animals to detect electric fields.

    Next, Hanke and his team tested a live dolphin, a 28－year－old named Paco, to see if he could recognize an electric field. They taught Paco to swim close to a device that could create a weak electric field in the water. Then the team taught Paco to swim away from the device if he detected any changes. When the scientists created an electric field, Paco swam away—showing that he knew something had changed. When there was no electric field, Paco stayed there. When Paco's snout was covered in plastic, he didn't react to the electric field.

    Paco's behavior told the scientists that the dolphin used his snout to detect the tiny electric field. "This is a major breakthrough," Peter Madsen, a sensory biologist, said.

    Dear Sir,

    I am writing about your January bill, which I am returning with this letter. I am not going to pay this bill. Last month I bought a table and four chairs for $65.50. They were sent to me on December 18. That night one leg of the table broke while my wife was putting our dinner on it. It fell on one of the chair, and that broke, too. Our $ 2.50 steak landed on the floor, and the dog ate it.

    I spoke to the salesmen who had sold me the table and the chairs. He told me to write you a letter. I wrote you on December 20, saying that I was not going to pay for the furniture. On December 21 some men came and took it back to the store.

    Please do something about your records. I do not want to receive another bill for the furniture which I returned.

Yours truly,

Alberts Robbins
