     When you leave school, you_can_breathe_a_sigh_of_relief_and_leave_learning_behind, right?
Wrong! Learning should last a lifetime. You exercise your body to stay strong, and you should exercise
your mind to stay sharp.
                                                      
     An English idiom says, "You can't teach an old dog new tricks." But scientists have discovered that
isn't true. Older people can learn, and they should, in order to keep their brain active. Now a new trend
has begun in several states in the US that encourages learning. Adults can attend One Day University.
They can spend a Saturday or Sunday hearing four 70-minute lectures. Each one is given by a top
university professor. One of the original participants said, "It's like a health club for the brain." Also,
universities like MIT have made all of their courses and lectures available online for free! Libraries offer
learning programs too. With so much available, there is no excuse not to learn!
     Learning is a habit.Don't leave it behind after you leave school. On the website lifehack.org, author
Scott Young mentions several things to help you.
     Always have a book. It doesn't matter if you read fast or slow. Just read.If you read just one book a
week, you'll read 52 over the course of a year. Think of the knowledge you'll gain!
     Practice it. As you read, do something with what you've learned. Don't just enjoy the mental exercise.
Use the knowledge. If you read about painting, try it!
     Make a "to learn" list. Compose a "to learn" list for yourself. Maybe you want to speak better English, play the piano, or cook French food. Whatever interests you, put it on your list and then make the time to do it. Teach others. Whatever you learn, teach someone else. You'll not only help others but also
understand what you've learned.

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(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.
