If you are sitting, please stand up. Move your legs. Touch your toes if you can. Do anything but sit. New research shows that if you cut down on the time you spend sitting, you might live longer. Sitting less than three hours a day might extend your life by two years. Cutting television time to less than two hours a day can add one point four years to life.

    The human body is designed to move. The fact is just the opposite. Modern lifestyles and office jobs rarely give us the chance to move around. We sit while we're eating; we sit in the car; we sit while we are watching TV. And most of us sit for many hours at work. Sitting is something we do all the time. On average, Americans sit for four and a half to five hours a day. But that does not make sitting good for us.

    Though you may exercise often, that does not mean you can sit for the rest of your waking hours. We can't throw away physical activity. It is extremely important. Even if you exercise for 30 minutes a day, what goes on in the other 23 and a half hours a day is also very important.

    Changes are coming to some offices, especially in the design of desks. A “standing desk” lets people stand while they work. Another new design is called the “treadmill desk”. It is an exercise machine that lets you walk slowly in one place. Even some U.S. schools begin to experiment with desks that are part bicycle to keep children moving.

    Many companies may not buy a standing desk for everybody. However, they may get five standing desks or a treadmill desk for their employees and put them in a certain place where people can go for an hour a day to answer their emails or talk on the phone. Experts suggest some other activities: take a walk at lunchtime; walk to the offices and talk directly instead of emailing colleagues. All these activities may help you live longer.

    I'm a real book lover. Every time my friends visit me, my nose is buried in a book. Wherever I go, I always have a book with me. Novels, history books, stories about people, journals and news—I read them all and I've learnt a lot, too. For example, many things in life happen for the best even if we don't like or understand them.

    Why is reading such an enjoyable pastime for me? I probably first learned about it from my parents. My mother read to me at night in my childhood and bought me picture books. The greatest gift she has given me is a love for reading. And it will be a life-long habit.

    No one ever asked me why I liked to read. They just saw me and asked, "Oh? Is that for school work?" And I just shook my head, "No. It's just for fun." While reading a good book, I can totally forget myself and fly to another world. It's like exploring through someone's eyes, which is just as exciting as watching a movie.

    Reading is also necessary in order to learn about writing, to improve my use of words and phrases and broaden my knowledge. What a pity to see our imagination disappear, for we don't exercise it often. Reading can even be good for one's health, I think. Everyone should read sad stories that make us cry and also books with humor that make us laugh out loud!

    My mother has a dining table which sits right in the middle of her dining room. It was once buried beneath piles of papers—magazines, articles, copies of schedules for vacations she took back in the 1990s, and baby pictures of grand children who are now paying off their college loans.

    My brother Ross and I recently flew to New York to visit my mother. "Mom, why don't we go through all that stuff?" Ross said. "No. Don't touch it!" My mother said. The next afternoon, when she couldn't find a bill she needed, Ross suggested it might be put somewhere in the dining room and that we find it together. "Besides," he said, "all those papers are clearly stressing you out." However, my mother just said, "Are you boys hungry?" And then she seemed to have lost herself in deep thought.

    On our last night there, my mother walked up to us with a small pile of unopened mails, which she had collected at the western edge of the dining table, and said, "Help me go through these." "Sure," I said. When we had succeeded in separating wheat from chaff (谷壳), I asked, "Would you want to deal with another little pile of papers?"

    My mother led the way  walking into the dining room the way an animal manager might be while entering a cage with tigers in it. Ross and I came in behind her and suddenly he reached for a pile of the papers on one side of the table. "No!" my mother said sharply. "Let's start at the other end. That's where the older stuff is." Finally, we threw 95 percent of the stuff into paper shopping bags. Then I asked what she wanted us to do with them, she surprised us all by saying, "Put them in the incinerator (垃圾焚化炉)."

    When I returned home, inspired by the visit to my mother, I sorted out my own accumulated(累积的) piles of papers, sold or gave away half of my possessions, and moved into a smaller house. It seems that my life has been cheaper and easier since then. And it proves that a small change does make a big difference.

    My grandmother often said to me, "You can count the number of your true friends on the fingers of one hand." For a long time I thought this was true. However, I've now discovered my grandmother was only half right. Maybe we do only make a few "best" friends in our lifetime, but those aren't the only people that we can call friends. There are many different types. Let me tell you about a few of them.

    One type of friends is the type I call the "football mom friends". My neighbour Sally is a good example. We both have kids who play football in a football club, and someone has to take them to practise and pick them up. Sally and I and two other mothers do this. We meet sometimes and have tea and talk about what our kids are doing, but those are the only times that we meet each other. I enjoy being with these women, but we don't do anything else together.

    Another type is called the "hobby friend". That's the person you share an interest or a hobby with. Michael and Cater, who are brothers, are a good example of this type. We're all in a bird watching club. Every few weekends the members of the club go on a trip to watch different kinds of birds. There's nothing romantic about my relationship with Michael and Cater, of course. We just share interest in birds.

    Then there's the "other half the couple" type of friends. Jim is married to Rose, a friend that I have known since college. When Rose married Jim, I realized that I would have to be Jim's friend if I want to continue to be Rose's. Jim and I don't share so many interests, but we do have a friendly relationship.

The blue whale holds the current record as the largest creature to live on Earth, but a collection of bones found in Per u might break that record. Researchers have identified a whale species called Perucetus colossus in the publication Nature. Bones from this species, including backbones weighing over 100 kilograms each and ribs measuring nearly 1. 4 meters long, were found by Mario Urbina in 2012 in the Ica desert.

The area where the bones were found was once underwater, making it a rich source of ocean fossils. The find resulted in 13 backbone vertebrae(脊椎), four ribs and a hip bone. The large fossils date back to around 39 million years ago. Alberto Collareta, a lead writer of the study, described the fossils as unlike anything he had ever seen before.

The researchers used 3D scanners to study the bones' surface and also looked inside. Based on the incomplete skeleton, the team estimated that the ancient creature weighed somewhere between 85 and 340 metric tons. Comparatively, the largest blue whales found fell within that range, at around 180 metric tons. The Perucetus colossus measured about 20meters long, while blue whales can reach 30 meters in length. This means the newly discovered whale was "feasibly the heaviest animal ever," said Alberto Collareta. But he added, "it was most likely not the longest animal ever."

Interestingly, the density and weight of the Perucetus colossus' bones were much higher than those of a blue whale. This suggests that the colossal whale may have inhabited shallower coastal waters, similar to other coastal animals with heavy bones.

Another researcher, Amson, said, without the skull, it is hard to know what the whale was eating to support such a huge body. It is possible that the large creature sought food along the seafloor, the researchers said. Or it could have eaten up tons of smaller sea life in the ocean. Swiesen, a paleontologist, added that he would not be surprised "if this thing actually fed in a totally different way that we would never imagine."
