     When I was a boy, my father told me that he could do anything he wanted to.Dad said that he wanted
to be the first to develop color prints in our city, and so he did.
     When I was 16, Dad looked closely at the violin I played and announced that he wanted to make
one.  He read about violin making, and then became a violinmaker at the age of 43.He bought the tools
and materials, opened a small store and set Mom up as the shopkeeper, while he worked at a local
company.He retired from the company 17 years later and continued to make violins and other instruments.
     Dad often guessed why the Stradivarius violins sound so beautiful.Some experts claimed that it was
the unique varnish that gave those instruments their beautiful sound.Dad argued that chemists could
analyze the varnish-if that were the answer.
      One of Dad's friends asked him once which kind of wood wasused to make violins.When Dad
explained that the top wasmade of spruce, his friend said that he had an old pieceof spruce Dad might be
interested in.He worked for the next 12 months making a violin from thewood that his friend had given
him.It proved to be a superior violin and it would become Dad's masterpiece.He was convinced that the
secret of the Stradivarius sound was in the wood itself.
     Later, the instrument was stolen.Dad's spirit was broken by the robbery, and he stopped making
instruments.
But he kept the music shop until he was 80 years old, selling guitars and violins.

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.
