Your New Year's plan to move more is one of the toughest to stick to, and a group of scientists working with obese(过度肥胖的) mice think they're starting to understand why

    Rather than our sedentary(久坐的) lives causing weight gain, says Alexxai Kraviz, the National Institutes of Health neuroscientist who led the study, changes in brain chemistry after we start gaining weight affect our capacity to move.

    “Obses mice can move just fine,” says Kravitz, who published the work with his team in Cell Metabolism “They just don't.”

    What Kravitz's team found is that the activity of a particular dopamine(多巴胺) receptor linked to movement goes down as mice gain weight on a high-fat diet. So the nice slow down and they move less. And when the researchers restored the activity of that dopamine receptor—DR2—the mice started moving more, even though they were still obese. The team also saw that lean mice missing the DR2 receptor acted like obese mice. This is the target, says Kravitz—restoring that dopamine receptor function. “Maybe 20 or 30 years down the road, we could do that in people,” he says.

    And there is one more thing: The scientists fed normal mice and the mice lacking DR2 the same high-fat diet. Both sets of mice gained weight at the same rate.

    Kravitz says this is important because mice lacking DR2 move less from the get-go, whereas a normal mouse takes a little time to start seeing that dopamine receptor-related loss of exercise. The ability to exercise seems to be disconnected from weight gain, he says.

    “Exercise is a healthy thing to do, but its impact on weight loss has been exaggerated,” he says. “We have to be realistic about the size of the effect of exercise on weight, as opposed to health benefits.”

    Still, before you abandon your New Year's exercise plan, keep in mind that this study was done using a high-fat diet, and not the normal calorie restriction that people maintain when they diet.

    That's a big drawback to the work, says Vicki Vieira-Potter, a University of Missouri physiologist not involved in the study.

    “They feed the mice with high-fat diet, it damages the receptor, and that decreases activity. Those who plan to lost weight should remember high-fat diet is a nice way to cause obesity in the lab, but it's not the same as the normal situation of obesity,” she says.

    Sine also says that a lot of the weight gain in the mice came after they stopped moving around, which indicates that the loss of movement did impact obesity.

    It's also important to consider how what you're buying will affect how you spend your time.For example,you may have to spend a very long time on the road if you get a big house in the suburb,which will totally lower overall life satisfaction.

    Try giving it away.

Elizabeth Dunn,associate professor of psychology at the University of British Columbia in Canada,found that in countries as diverse as Canada,South Africa and Uganda,giving away money consistently made people happier. {#blank#}5{#/blank#}A.Buy what you like.

    The St. Louis Post-Dispatch reported that the St. Louis Outlet Mall is expanding its restrictions on unaccompanied teenagers. In 2006, a parental-escort (陪同)policy was established: on Fridays and Saturdays starting at 6 p.m., anyone under 17 that isn't accompanied by a guardian who is at least 21 years old will be kicked out of the mall. It was around this time that other malls around the U.S. likewise banned unaccompanied teens during certain evening hours.

Starting from this Friday, the St. Louis Outlet Mall is pushing its parental-escort rule back to 3 p.m. on Fridays and Saturdays. Similarly, the Mall of America expanded its parental-escort policy during the recent holiday shopping season. Normally, the policy bans kids under 16 without guardians(监护人) from 4 p.m. until closing time just on Fridays and Saturdays. But because of a fight in the mall involving dozens of young people that took place on Dec. 18, 2012—- a weekday, the policy was broadened to include peak 2013 holiday shopping hours, including Thanksgiving Day and all of the Christmas week.

    Teen disturbances in other malls may cause more shopping centers to introduce or expand parental-escort policies. The Indianapolis Star noted that two incidents in 2013 in area shopping centers raised the possibility that Indianapolis malls might need to consider banning unaccompanied teenagers.

   Obviously, such bans are aimed at stopping violence and other outbursts involving teenagers. More importantly, from a purely business perspective, these bans aim to attract shoppers who might otherwise be hesitant to go to the mall because of concerns about violence and outbursts involving teenagers. The restrictions allow mall security officers to systematically kick out a group of people that are considered to be loud, thuggish and bad for business overall. But they attract much criticism from online communities. Some argue that teens have the right to shop without a guardian. “Not all teens are disrespectful and troublemakers,” Pamela Chapman wrote. “In fact, it's been my experience that most are good kids.”

Again, the biggest influence on stricter mall policies for teens seems to be that they're just plain good for business. Malls reported strong sales growth after they first carried out the policies six years ago. “We've had some success with the parental-escort policy, and families like shopping out here together,” the manager of the St. Louis Outlet Mall told the St. Louis Post-Dispatch . If there's one rule in retail, it's this—- if a small initiative proves successful in boosting sales, then it's all but guaranteed that a larger initiative will follow.

    In 2004 ,when my daughter Becky was ten , she and my husband ,Joe, were united in their desire for a dog . As for me , I shared none of their canine lust.

    But why , they pleaded. “Because I don't have time to take care of a dog.” But we'll do it. ” Really? You're going to walk the dog? Feed the dog? Bathe the dog?” Yes, yes , and yes .”I don't believe you .” We will . We promise.

   They didn't . From day two (everyone wanted to walk the cute puppy that first day ) , neither thought to walk the dog . While I was slow to accept that I would be the one to keep track of her shots , to schedule her vet appointments , to feed and clean her , Misty knew this on day one . As she looked up at the three new humans in her life (small, medium, and large) , she calculated ,”The medium one is the sucker in the pack .”

    Quickly, she and I developed something very similar to a Vulcan mind meld (心灵融合) . She'd look at me with those sad brown eyes of hers , beam her need , and then wait , trusting I would understand — which , strangely , I almost always did . In no time , she became my feet as I read , and splaying across my stomach as I watched television .

    Even so , part of me continued to resent walking duty . Joe and Becky had promised. Not fair , I'd balk (不心甘情愿地做) silently as she and I walked . “Not fair , ” I' d loudly remind anyone within earshot upon our return home .

    Then one day — January 1, 2007 , to be exact — my husband ‘ s doctor uttered an unthinkable word : leukemia ( 白血病) .With that , I spent eight to ten hours a day with Joe in the hospital , doing anything and everything I could to ease his discomfort. During those six months of hospitalizations, Becky, 12 at the time, adjusted to other adults being in the house when she returned from school. My work colleagues adjusted to my taking off at a moment's notice for medical emergencies. Every part of my life changed; no part of my old routine remained.

    Save one: Misty still needed walking. At the beginning, when friends offered to take her through her paces, I declined because I knew they had their own households to deal with.

    As the months went by，I began to realize that I actually wanted to walk Misty. The walk in the morning before I headed to the hospital was a quiet, peaceful time to gather my thoughts or to just be before the day's medical drama unfolded. The evening walk was a time to shake off the day's upsets and let the worry tracks in my head go to white noise.

    When serious illness visits your household, it's , not just your daily routine and your assumptions about the future that are no longer familiar. Pretty much everyone you acts differently.

    Not Misty. Take her for a walk, and she had no interest in Joe's blood counts or 'one marrow test results. On the street or in the park, she had only one thing on her mind: squirrels! She Was so joyous that even on the worst days, she could make me smile. On a daily basis she reminded me that life goes on.

After Joe died in 2009，Misty slept on his pillow.

    I'm grateful一to a point. The truth is, after years of balking, I've come to enjoy m' walks with Misty. As I watch her chase after a squirrel, throwing her whole being into the here-and-now of an exercise that has never once ended in victory, she reminds me, too, that no matter how harsh the present or unpredictable the future , there's almost always some measure of joy to be extracted from the moment.

    Washing habits have changed over the years. In the 16th century, most people had a bath once a month…if they were lucky. Up until the 1950s, it was once a week. Only just recently has the concept of daily showering become popular. But now, according to the New York Times, things are changing again.

    The latest trend is known as "soap-dodging". It basically consists of washing less, having fewer showers and using less soap. "I just wash my hair once a month now," said Brett Dawson, a 32-year-old management consultant. "I have just one bath a week," said Miriam Bayliss, a 28-year-old accountant.

    And it appears to be growing in popularity. A poll last year for tissue manufacturer SCA found that 41% of British men and 33% of women don't shower every day. And 12% of people have a proper wash just once or twice a week. Further research by Mintel found that more than half of British teenagers don't wash every day-with many opting for a quick spray of deodorant (除臭剂) to mask any smell. But why?

    There are a variety of reasons. Some claim that daily hair-washing is unnecessary. Commentator Matthew admitted that he hadn't shampooed his hair for a decade. Others say they just don't have the time. In 2008, the chemist Boots reported a 45% rise in sales of dry shampoo - a product that can be sprayed on hair between showers.

    And some people want to help the environment. "I limit my showers to about twice a week," said Nigel Hamerstone, a 42-year-old architect. "The rest of the time I have a sink wash." he adds. "I believe that I'm as clean as everyone else, and it's helped get my water consumption down to around 20 litres a day - well below the 100 to 150 average in the UK."

    So, will you be joining the new "washing revolution"?
