英语翻译
Jeanne Calment took up skating at age 85 ,made her first movie appearance at
age
1 14 ． and held a concert in the neighborhood on her 121 st birthday ．
When it comes t0 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 1 22
,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 ’ 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 ．

雅娜·卡尔芒85岁开始滑冰,114岁登上银幕,并且还在121岁时举办了一场邻里音乐会.
雅娜·卡尔芒可以说是世界长寿纪录保持者,她活了122岁.那么122岁就是人类寿命极限吗?如果科学家能够开发出一种延缓衰老的药物或食谱,那么我们有可能活到150岁甚至更久吗?
对此研究人员们也莫衷一是,德克萨斯大学的杰瑞·西说“卡尔芒活到了122岁,所以如果
有人活到130或135都不算稀奇”,同校的斯蒂夫·奥斯塔表示同意：“人类寿命极限比我们想象的更长,过去的专家还认为人类活不过110岁,但是当卡尔文打破了这个数字后,他们又将人类寿命极限增加到120.既然如此,那我们为什么不能说得更高?”
然而所有对人类寿命极限的预测都不过是猜测.密歇根大学的里奇·米勒认为：“任何人都可以说出个数字,通常说得最高的科学家名字会出现在杂志上”,米勒说,“难道不会出现新的抗衰老技术,可以将人类寿命延长到几个世纪?任何延缓衰老的手段都有可能将人类寿命延长至120岁.研究人员现在已开发出将老鼠寿命延长50%的药品,因此如果人类的平均寿命是80岁,那么增加50%就是12岁.”
“那么从学者的分歧中我们能得到什么启发呢?那就是寿命是可以改变的,但有一定的极限”,华盛顿大学的乔治·马丁谈到,“我们能让苍蝇增加50%的寿命,但是一只苍蝇永远活不到150岁”.他还补充道：“当然,如果你进化成一个新物种,衰老较慢的物种,那就另当别论了.”马丁真的认为人类可以得到进化延长寿命吗?他笑着说“这个问题很酷”.
