Jeanne Calment took up skating at age 85, made her first movie appearance at age114.and held a concert in the neighborhood on her 121 st 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(限制)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 sul33rise 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 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 1 20.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 guessing
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 HS living until about 120.Researchers are working on treatments that make the life span of mice longer by 50 percent at most.
So, if the average(平均)human life span is about 80 years, says Miller,“adding another 50 percent would get you to 120.”
So what can we learn 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'snever 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.

Eric Wilson, the reporter from Lifestyle Magazine, interviews two persons on how they spend their day.Read what they say and answer some questions.
My name’s Stella.I usually leave at around eight fifteen.It takes me around forty minutes, and we start at nine-sharp.I take a coffee break at eleven, and then have my lunch at one o’clock.Pretty much the same hours as most people, I guess.I generally get home around six o’clock, have a snack, and then watch the news on TV at seven.I eat around eight, watch more TV or read a book, and try to be in bed by ten.Pretty boring, really, but that’s life.
My name’s Sophie.You ask my daily routine---that’s kind of a strange thing to ask.Still, if you really want to know…I get up around eleven thirty, and I hang out and read the paper and drink some tea.Then I go to the gym around twelve thirty, till about one fifteen, I guess.Well, then I might do some shopping or visit a friend.I usually have something to eat around three thirty, and I leave home at six thirty, and get to work around seven.I work until eleven.I’m usually home by eleven thirty.I have a meal, watch TV or a video, and try and be in bed by one o’clock.Unusual, maybe, but I like it.
