　　Years ago a John Hopkin’s professor gave a group of graduate students this task: Go to the slums（平民窟）. 　31 200 boys, between the ages of 12 and 16, and 　32 their background and environment. Then predict their 　33 for the future.
　　The students, after 　34 social statistics, talking to the boys, and collecting much data, 　35　that 90 percent of the boy would spend some time in 　36 .
　　Twenty-five years later another group of graduate students was 　37 the job of testing the 　38 . They went back to the same area. Some of the boys— 39 men—were still there，a few had died，some had moved away， 40 they got in touch with 180 of the 　41 200. They found that only four of the group had ever been sent to prison.
　　　42 was it that these men，who had lived in a breeding place of crime，had such a 43 good record？ The researchers were continually told，“Well，there was a teacher…”
　　They pressed 　44 ，and found that in 75 percent of the 　45 it was the same woman. The researchers went to this teacher，now living in a home for retired 　46 . How had she had this remarkable influence 　47 that group of children？ Could she give them any reason why these boys 　48 have remembered her？
　　“No，”she said.“No I really couldn’t.”And then, 　49 back over the years，she said musingly，more to herself than to her 　50 ，“I loved those boys…”

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.
　　    When 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（寿命）? 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（有弹性的）, 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 （物种）, one that ages at a slower speed, that would be a different story, he adds.
　　    Does Martin really believe that humans could evolve （进化）their way to longer life? “It’s pretty cool to think about, ”he says with a smile.
