  When the world was a simpler place, the rich were fat, the poor were thin, and right-thinking people worried about how to feed the hungry.Now, in much of the world, the rich are thin, the poor are fat, and right-thinking people are worrying about fatness.

  Evolution(進(jìn)化)is mostly to blame.It has designed mankind to deal with lack, not plenty.

  People are perfectly fit to store energy in good years to see them through lean ones.But when bad time never comes, they are stuck with that energy, stored around their expanding bellies.

  Thanks to rising agricultural productivity, lean years are rarer all over the globe.According to the UN, the number of people short of food fell from 920 m in 1980 to 799 m 20 years later, even though the world’s population increased by 1.6 billion over the period.This is mostly a cause for celebration.Mankind has won what was, for most of his time on this planet, his biggest battle:to ensure that he and his offspring had enough to eat.But every silver lining has a cloud, and the result of prosperity is a new trouble.

  Fatness is the world’s biggest public-health topic today-the main cause of heart disease, which kills more people these days than AIDS, malaria(瘧疾), war;the major risk factor in diabetes(糖尿病);heavily connected with cancer and other diseases.Since the World Health Organization labeled fatness an“epidemic(流行病)”in 2000, reports on its fearful results have come thick and fast.

  Will public-health warnings, combined with media pressure, persuade people to get thinner, just as they finally put them off tobacco? Possibly.In the rich world, sales of healthier foods are booming and new figures suggest that over the past year Americans got very slightly thinner for the first time in recorded history.But even if Americans are losing a few ounces, it will be many years before the country solves the health problems caused by half a century’s dining to overload.

  And, everywhere else in the world, people are still piling on the pounds.That’s why there is now an agreement among doctors that governments should do something to stop them.

How Long Can People Live?

  She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121st birthday.

  Whe n it comes to long life, Jeanne Calment is the world’s recordholder.She lived to the ripe old age of 122.So is 122 the upper limit to the human life span(壽命)?If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150-or beyond?

  Researchers don’t entirely agree on the answers.“Calment lived to 122, so it wouldn’t surprise me if someone alive today reaches 130 or 135,”says Jerry Shay at the University of Texas.

  Steve Austad at the University of Texas agrees.“People can live much longer than we think,”he says.“Experts used to say that humans couldn’t live past 110.When Calment blew past that age, they raised the number to 120.So why can’t we go higher?”

  The trouble with guessing how old people can live to be is that it’s all just guessing.“Anyone can make up a number,”says Rich Miller at the University of Michigan.“Usually the scientist who picks the highest number gets his name in Time magazine.”

  Won’t new anti-aging techniques keep us alive for centuries?Any cure, says Miller, for aging would probably keep most of us kicking until about 120.Researchers are working on treatments that lengthen the life span of mice by 50 percent at most.So, if the average human life span is about 80 years, says Miller,“adding another 50 percent would get you to 120.”

  So what can we conclude from this little disagreement among the researchers?That life span is flexible(有彈性的),but there is a limit, says George Martin of the University of Washington.“We can get flies to live 50 percent longer,”he says.“But a fly’s never going to live 150 years.”

  “Of course, if you became a new species(物種),one that ages at a slower speed, that would be a different story,”he adds.

  Does Martin really believe that humans could evolve(進(jìn)化)their way to longer life?“It’s pretty cool to think about it,”he says with a smile.

C.

few people can expect to live to over 150

D.

researchers are not sure how long people can live

(3)

Who would agree that a scientist will become famous if he makes the wildest guess at longevity?

[  ]

A.

Jerry Shay.

B.

Steve Austad

C.

Rich Miller

D.

George Martin

(4)

Most of us could be good at sports even at 120.

The average human life span cannot be doubled.

C.

Scientists believe mice are aging at a slower speed than before.

New techniques could be used to change flies into a new species.
