When Boris left school, he could not find a job．He tried hard and pestered(纠缠)his relatives, but they had problems of their own．He answered advertisements until he could not afford to buy any more stamps．Boris grew annoyed, then depressed, then a little hardened．Still he went on trying and still he failed．He began to think that he had no future at all．
“Why don't you start your own business?” one of his uncles told him．“The world is a money-locker．You'd better find a way of opening it．”
“But what can I do?”
“Get out and have a look round．” advised his uncle in a vague sort of way．“See what people want; then give it to them, and they will pay for it．”
Boris began to cycle around the town and found a suitable piece of a waste ground in the end．Then he set up his business as a cycle repairer．He worked hard, made friends with his customers and gradually managed to build up his goodwill and profit．A few months later, he found that he had more work than he could deal with by himself．He found a number of empty shops but they were all no good：in the wrong position, too expensive or with some other snag(障碍)．But at long last, he managed to find an empty shop on a new estate where there were plenty of customers but no competition．
Boris and his assistant taught themselves how to repair scooters and motor-cycles．Slowly but surely the profits increased and the business developed．At last, Boris had managed to open the money-locker and found bank notes and gold coins inside．

Boris finally chose an empty shop on a new estate because．
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(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 it,”he says with a smile．
