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’（老年癡呆癥）.

“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.

Food is life; it gives us the nourishment (營(yíng)養(yǎng)) we need to stay alive and be healthy. __1.__ Brian Wansink, a professor at the University of Illinois, says we also eat certain foods because they make us feel good, and remind us of happy memories. Wansink calls this kind of food comfort food. For some people, ice cream is a comfort food. For others, a bowl of noodles soup makes them feel good.

__2._ Professor Wansink believes that we connect food with important times, feelings, and people in our lives. “When I was a child, my mother made a delicious soup; I loved it. __3.__ And it helps me feel better,” Says one of Wansink’s coworkers.

Do men and women choose different comfort foods? Wansink’s research at the University of Illinois says “ yes”. In his study, the favorite comfort food for both men and women was ice cream. After this, men usually preferred hot, savory (香的) foods like soup or noodles. __4.__ Men and women like to eat comfort foods when they are happy, but women eat these foods more when they are sad or worried.

__5.__ About 40 percent of the comfort foods in Wansink’s study were healthy main dishes or soups and vegetables. It shows, says Wansink, that a comfort food can taste good and be good for you.

Not all comfort food is junk food.

Where can we buy this sort of food?

Sweet foods are also their preference.

How does a food become comfort food?

Usually, we eat because we are hungry or need energy.

Women like sweet things such as chocolate and cookies.

Now, I often have this kind of food when I am tired or worried.
