　　Researchers have established that when people are mentally engaged, biochemical changes occur in the brain that allow it to act more effectively in cognitively areas such as attention and memory. This is true regardless of age.

　　People will be alert and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an ac-tive mind.

　　Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives. The idea is not necessarily to learn to mem-orize enormous amounts of information, says James Fozard, associate director of the Na-tional Institute on Aging. Most of us dont need that kind of skill. Such specific training is of less interest than being able to maintain mental alertness. Fozard and others say they challenge their brains to work.

　　Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep men-tally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. The point is, you need to do both. Cohen says, Intel- lectual activity actually influences brain-cell health and size.

　　参考译文

　　研究学者已经得出观点，当人们开动脑筋时，大脑中发生的生化变化，使它在诸如注意力和记忆力等的认知领域表现得更有效率。不论年龄大小，情况都一样。

　　当人们面对的信息可以使他们联想到感兴趣的事物时，便会警觉起来，易于接受。而在步人老年时，习惯于比较多地进行这种活动的人比那些从来没有积极主动思考的人的认知心理明显健康。

　　许多专家确信，挑战大脑是有好处的，因此他们将这一理论实践于自己身上。国立老龄研究所的副主任James Fozard说：问题不在于非得学会记忆大量的信息。我们大多数人并不需要那种技巧。这种特别培训的意义不及使得大脑保持警觉的意义那么大。Fozard与其他人都宣称他们挑战自己的大脑以使其T作。

　　Gene Cohen是同一研究所的主任，他建议年纪较大的人参加脑力与体力活动时应使个人行动和集体行动兼而有之。Cohen说我们通常得到的建议是在年纪增长时要坚持身体上的活动，但老人也需要保持大脑的运转。这样做的人更有可能保持其智力水平，他们也通常更加愉快，能更好地调节自己的生活。Cohen说，关键是，你得双管齐下。脑力活动的确对脑细胞的健康与大小有影响。
