Sorry to say,our brains naturally start slowing down at the Cruelty young age of 30.It used to be thought that this couldn’t be helped,but new studies show that people of any age can train their brains to work faster.“Your brain is a learning machine,”saying University of California scientist Dr. Michael Merzenich.Given the right tools,we can train our brains to act like they did when we were younger.All that’s required is the practice designed just for the purpose:a few exercises for the mind.

Merzenich has developed a computer-based training method to speed up the process(过程) in which the brain deals with information (positscience.com).Since much of the data we receive comes through speech,the Brain Fitness Program works with language and hearing to better speed and accuracy(准确性).

Over the course of training,the program starts asking you to distinguish(辨别) sounds (between“dog”and“bog”,for example) at an increasingly faster speed.It’s a bit like tennis instructor,says Merzenich,hitting balls at you—faster and faster to keep you challenged(受到挑战).You may start out slow,but before long you’re pretty quick.

The biggest finding in brain research in the last ten years is that the brain at any age is highly plastic.If you ask your brain to learn,it will learn.And it may even speed up while in the process.

To keep your brain young and plastic you can do one of a million new activities that challenge and excite you:playing table tennis or bridge,doing crossword puzzles,learning a language...“When it comes to preventing ageing,you really do ‘use it or lose it’,”says Barbara Sahakian,professor at Cambridge University.

This is a story from 28 years ago. My dad was a used car salesman. Every Thursday night, he would head off to Shreveport, LA for an auction. Most of the time, I drove a car over there for him so he could sell it at the auction.

One day, I was riding with my dad when he noticed a hitch-hiker with a backpack. Without hesitation, he pulled the car over and offered him a ride. Dad asked him his name, and proceeded to talk to him about all sorts of things. Dad asked him where he was going. The hitch-hiker told him he was heading for the west. I can’t recall why but he told Dad a lot of things that had occurred to him and that persuaded him to make that decision. He talked about the tragic events that occurred to him several years before. He was low in spirits, but I could see that the hitch-hiker’s attitude was changing as someone was really listening to him.

We drove 45 minutes before the hitch-hiker got off. We pulled over and Dad told him to keep his head up and things would start looking up for him soon. He reached into his pocket and handed the hitch-hiker a twenty-dollar bill. The guy smiled. He nearly lit up right there on the cold, dark highway.

We drove on and my dad did not say a single thing. I was still completely amazed by what I had just witnessed. I was always told by everyone never to pick up a hitch-hiker and yet my dad did it every single time he saw one. While reflecting upon that story I came to understand that just one single kind act could change someone’s life, and I am sure that my father’s deed made that poor man’s day.

Everybody has to buy or sell things sometimes. Even students who are usually not very rich, have to learn something about making purchases intelligently. As a student, you may find, for example, that you need to a walkman or winter clothing. You may want to buy a television or a used car. Of course, you want to get good value for your money. If you are considering a major purchase, or any purchase you should remember several important things.

※Study first, and then decide what to buy. You can learn a lot just by reading books and advertisements.

 Remember that a high quality product will probably last longer and work better. Of course, for a superior product you are expected to pay more. An inferior product may not give you the same quality, but the price could be low. A poor quality product could be expensive and a valuable one could be on sale at a greatly reduced price.

※Don’t worry. Take your time. After you decide what product you want to buy, go to many different stores. If you cannot find the product you want, you try to order it directly from the factory or ask the store to order it for you.

Look for a good deal. If you wait, you may probably find that your product will go on sale and you may be able to save 10,20, or even 50 percent of the original price.

Finally, before you buy, make sure that that product is guaranteed. If you find the lowest possible price, you will generally be happy with your purchase and also keep more money in the bank.

Which of the following should you care more while shopping?
