If you're 70 and overweight, you may live longer
A few extra pounds might help you live longer if you're past your prime(壮年) but otherwise healthy, a new study finds.
Physicians routinely follow guidelines issued by the World Health Organization. Because weight depends on height, they use a standard measure called body mass index (BMI), which is calculated as the weight in kilograms divided by the height in meters squared.
Healthy weight is defined as a BMI anywhere between 18.5 and 24.9 in adults, whereas 25 to 29.9 is overweight and 30+ is obese.
The new study suggests that in the elderly, these boundaries may be too narrow. While no one is questioning that extra fat poses health risks in young and middle-aged adults, it may reduce the impact of frailty and old age, geriatrician(老年医学专家) Dr. Thomas Yoshikawa told Reuters Health.
So far, nobody knows exactly how BMI affects lifespan in older people. Some researchers speculate that it acts as an energy reserve that can help the elderly cope with illness.
For the study, Australian researchers followed more than 9,000 men and women who were between 70 and 75 years old at the beginning. The participants reported their height and weight as well as various factors related to health and lifestyle. About 33 percent of the women and 44 percent of the men were overweight.
Over 10 years, more than 2,000 of the participants died. Women who had an active life and didn't smoke were the most likely to be alive at the end of the study.
But neither health nor lifestyle could fully explain why overweight people of both sexes survived longer than their normal-weight peers, who fared no better than obese individuals. In terms of survival, the best BMI was between 26 and 27, well within the overweight range.
The new results agree with earlier research showing that fat may be beneficial in old age.

In 1975, George Carlin appeared on a popular TV show, Saturday Night Live, with his famous words about blue food. “Why is there no blue food? I can’t find blue food—I can’t find the flavor of blue! I mean yellow is lemon; orange is orange and red is cherry. Where is the blue food? ”
Well, Carlin pretty much has it right—there’s not no blue food, but there’s certainly not a lot of it. Fresh-picked blueberries are blue, though they become purple when they are turned into jam. The blue in blueberries—like the purple in grapes and the red in tomatoes—is found in nature. But it isn’t a hot color for food. People don’t seem to prefer blue food. Some diet programs even suggest that those determined to lose weight should make their food blue.
Eating, in part, begins with our eyes. Charles Spence—an experimental psychologist from Oxford University—points out that color can change our taste experience. Commonly, we consider red-colored foods up to 20% sweeter than they actually are; and green foods as being more sour. Spence suggests: human expectations may be influenced by our long history of watching - green fruits can become sweet as they grow up and turn red.
But what about blue? Except blueberries, much of the blue food we see these days is dyed blue artificially. Food producers argue that artificial color doesn’t do much harm to health. A lot of research shows that some physical problems of kids are related to food dyes—while other studies show no effects at all. Blue birthday cake or even blue-dyed chicken can be served on the dinner table. So what? George Carlin’s words are placed at the beginning of the passage to _______.

Everyone, please imagine, a big explosion breaks out as the plane takes us high in the sky. The plane is full of smoke and the engine sounds scary. Two minutes later, the engines are turned off. We are now sitting in a plane with no sound. And we can see: Life is over.
That really happened. In January 2009, I had a front-row seat on Flight 1549, the plane that crash-landed in the Hudson River in New York.
Now let me tell you the three things I learned when the silence came.
First, I thought about all the people I wanted to reach out to but didn’t. I thought about all the experiences I wanted to have but never did. I no longer wanted to put off anything in life. Second, I really regretted the time I wasted on things that did not matter. I decided to remove negative energy from my life. Third, I realized, wow, dying was not scary. But it was very sad just because I only wished I could have seen my kids grow up.
Fortunately, I was given the gift of a miracle of not dying that day. I was given another gift, with which I was to see into the future and come back and live differently.
About a month later, my wife and I were at a performance by my daughter, not much artistic talent. Yet, I’m crying. I realized that above all, the only goal in my life was to be a good father.
Audience, again, imagine the same thing happening on your plane. How would you change? What would you get done? And more than anything, are you being the best parent you can?

In a moment of personal crisis, how much help can you expect from a New York taxi driver? I began studying this question and found the answers interesting.
One morning I got into three different taxis and announced, “Well, it’s my first day back in New York in seven years. I’ve been in prison.” Not a single driver replied, so I tried again. “Yeah, I shot a man in Reno.” I explained, hoping the driver would ask me why, but nobody asked. The only response came from a Ghanaian driver, “Reno? That is in Nevada?”
Taxi drivers were uniformly sympathetic when I said I’d just been fired. “This is America,” a Haitian driver said. “One door is closed. Another is open.” He argued against my plan to burn down my boss’s house. A Pakistani driver even turned down a chance to profit from my loss of hope; he refused to take me to the middle of George Washington Bridge—a $20 trip. “Why you want to go there? Go home and relax. Don’t worry. Take a new job.”
One very hot weekday in July, while wearing a red ski mask and holding a stuffed pillowcase with the word “BANK” on it, I tried calling a taxi five times outside different banks. The driver picked me up every time. My ride with a Haitian driver was typical of the superb assistance I received.
“Let’s go across the park.” I said. “I just robbed the bank there. I got $25,000.”
“$25,000?” He asked.
“Yeah, you think it was wrong to take it?”
“No, man. I work 8 hours and I don’t make almost $70. If I can do that, I do it too.”
As we approached 86th and Lexington, I pointed to the Chemical Bank.
“Hey, there’s another bank,” I said, “Could you wait here a minute while I go inside?”
“No, I can’t wait. Pay me now.” His reluctance may have something to do with money—taxi drivers think the rate for waiting time is too low—but I think he wanted me to learn that even a bank robber can’t expect unconditional support.Why did the Pakistani driver refuse to take the author to the middle of the George Washington Bridge?
| A．Because he was able to help the author to find a new job. |
| B．Because he wanted to go home and relax. |
| C．Because it was far away from his home. |
| D．Because he thought that the author would commit suicide. |
What is the author’s interpretation of the driver’s reluctance “to wait outside the Chemical bank”?
| A．The driver thought that the rate for waiting time was too low. |
| B．The driver thought it wrong to support a taxi rider unconditionally. |
| C．The driver was frightened and wanted to leave him as soon as possible. |
| D．The driver did not want to help a suspect to escape from a bank robbery. |
Which of the following statements is true about New York taxi drivers?
| A．They are ready to help you do whatever you want to. |
| B．they often refuse to pick up those who would kill themselves. |
| C．They are sympathetic with those who are out of work. |
| D．They work only for money. |
