How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question, as Tracy Smith reports in our Cover Story.

There are now more than a thousand genetic（基因的）tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’（老年痴呆症）.

“If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up.” Said Dr. Robert Green, a Harvard geneticist.

“Every ache and pain,” Smith suggested, could be understood as “the beginning of the end.”“That ’s right. If you ever worried you were at risk for Alzheimer’s disease, then every time you can’t find your car in the parking lot, you think the disease has started.”

Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s. It was thought that people who got bad news would, for lack of a better medical term, freak out. But Green and his team found that there was“no significant difference”between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.

旅行难道只能让人们享受美景放松心情吗？不，它还可以很有效果的降低犯罪率，这一点你相信吗？来看这篇文章吧

Americans think that travel is good for you, some even think it can help one of the country's worst problems-crime（犯罪）.

Crime worries a lot of people. Every year, the number of crimes goes up and up. And many criminals（罪犯）are young. They often come from sad homes, with only one parent or no parents at all.

There are many young criminals in prison. But prison doesn't change them. Six or seven in ten will go back to crime when they come out of prison.

One man, Bob Burton, thought of a new idea. In the old days, young men had to live a difficult life on the road. They learned to be strong and brave, and to help theft friends ill time of danger. This helped them to grow into men. So Bob Burton started" Vision Quest".

He takes young criminals on a long, long journey with horses and wagons（马车）, 3,000 miles through seven states. They are on the road for more than a year.

The young people on Vision Quest all have bad problems. Most of them have already spent time in prison. This is their last chance.

It's hard work on the road. The work starts before the sun comes up. The boys and girls have to feed the horses. Some of them have never loved anyone before. But they can love their horse. That love can help them to a new life.

Not all the young people on Vision Quest will leave crime behind them. Three or four in ten will one day_____________. Bob Burton is right. Travel can be good for you. Even today. Americans still say, “Go west, young man.”
