    Sorry to say, our brains pastorally start slowing down at the cruelly 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,” says 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 (過程) 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 mad hearing to better speed and accuracy (準確性).

    Over the course of training, the program starts asking you to distinguish (辨別)sounds (between “dog” and “bog”, for example) at an increasingly faster speed. It’s a bit like tennis instructor, says Merzenich, hitting balk at you faster and faster to keep you challenged(受到挑戰). 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 blain 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’s,”says Barbara Sahakian, professor at Cambridge University.
