VINCOUVER （Reuters）——South Korea' s Kirn Yuna can finally relax and does fiot need to think about the future after she won the gold medal in the women' s figure skating （花样滑冰）on Thursday．
The 19-year-old was the overwhelming （压倒性的）favorite to finish top of the podium （颁奖台） but said the pressure going into the event was large．
"I feel now as if a huge burden has been lifted, " the Games' highest-earning female athlete-she makes an estimated $8 million a year —said after her near-perfect program where she nailed all of her 11 jumps．
"I will enjoy this moment and think about things later．I was just thrilled on the podium and I feel so relieved．I had been running toward this dream of the Olympics and was so happy to be here, " she said．
"Since I have achieved the most important goal in my life．I am going to enjoy this moment for a while and then think about what I am going to do," a smiling Yuna said．
Japanese rival Mao Asada took silver while Joannic Rochette of Canada grabbed the bronze medal four days after her mother died．
"I still cannot believe I did what I wanted to do at the Olympics．I have been dreaming about this moment and I cannot believe it is not a dream any more．" said Yuna．
South Korea was counting on her to grab their first gold medal in figure skating and the first Winter Olympics gold medal outside short track and speed skating．
"I was just happy to have skated a clean program．It was the first time I skated two clean programs．During the program when I finished all elements I thought 'this is going to be yeah．．．this is it'．"[

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 121 st birthday.

    When it comes to long life, Jeanne Calment is the world’s record holder. 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.
