People with an impulsive personality refer to those who tend to do things without considering the possible dangers or problems first. According to a new study by researchers at the University of Georgia, such people may be more likely to have food addiction. The study found that people exhibiting impulsive behavior weren’t necessarily overweight, but impulsiveness was related to a direct relationship with food, and therefore, less healthy weight.

Food addiction has been compared to addictive drug use. Studies have linked the dopamine (多巴胺) release that occurs after tasting delicious food to the dopamine release that happens when people consume other addictive substances.

Impulsive behavior involves several personality traits (特点). Two of these traits, known as negative urgency and lack of perseverance, were particularly associated with food addiction and high BMI (身体质量指数) during the study.

Negative urgency is characterized by the tendency to behave impulsively when experiencing negative emotions. Some people might drink alcohol or take drugs. For others, it could mean eating to feel better. Lack of perseverance is when a person has a hard time finishing hard or boring tasks. People with a lack of perseverance might have difficulty attempting to change addictive eating behavior, which could also cause obesity.

“Impulsiveness might be one reason why some people eat in an addictive way despite motivation to lose weight,” said Dr. Ashley Gearhardt, a clinical psychologist. He was involved in developing the Yale Food Addiction Scale in aid of those people. “We are theorizing that if food addiction is really a thing, then our measure, the Yale Food Addiction Scale, should be related to helping control impulsive action,” said Gearhardt.

Clinical psychologist Dr. James MacKillop, whose lab was conducting the study, believes that therapies used to treat addictive drug behavior could help people who suffer from addictive eating habits.

“Most of the programs for weight loss at this point focus on the most obvious things, which are clearly diet and exercise,” MacKillop said. “It seems that managing strong desires to eat would naturally fit in with the skills a person would need to eat healthily.”

Have you ever had a day when everything seemed to go wrong, and nothing seemed to go right? Not too long ago I was having one of those days.I was discouraged, tired, and plain sad. My focus was on me.After all, no one else was experiencing the same trials I was.

I expressed my upset state to my mother, hoping for some pity.Instead, she said, “I heard Jamie was having a difficult day too.Why don't you make her some cookies and take them to her this afternoon?”

I didn't really want to, but decided that I didn't want to go back to my other problems just yet.I made the cookies and arranged them on a little plate.Then I made a card with a sunflower on it and wrote a small note of empathy(共鸣).

That afternoon I dropped by my friend's house.I went to the door and rang the bell. Soon, Jamie came to the door and looked at me in surprise for the unexpected visit. Before she could say anything I rushed, “I heard you were having a hard day and decided to bring you something. I hope your day goes better.” The look that came over Jamie's face was one that I could never put into words.It was as if a darkened sky was suddenly lit with the golden rays of the sun;it was as if in that small act, her day was brightened.

I got back into the car and for some amazing reason. I felt a lot better myself. That day I experienced the truth that James Barrie attempted to describe, “Those who bring sunshine to the lives of others cannot keep it from themselves.”

While I will explain a bit about the science of stress and relaxation a little later simple way to think about it is that our body 's stress response works like a car alarm. Keep us safe by warning us of the presence of danger in our immediate environment.

But instead of warning us with a loud and annoying sound,our body alarm system lets us know that something is wrong by creating changes in our neurochemistry (神经化学).If you've ever expe­rienced pain in your stomach,periods of extreme anger, inability to focus or even insomnia (失眠),chances are your body was paying the price in those moments for the brain chemistry of stress.

So if it's so uncomfortable,why not just get rid of stress altogether?

This is not only impractical,it would be dangerous. Let's go back to the metaphor (比喻说法)of the car alarm. If the alarm is turned off altogether,the car is exposed to continual danger without there being any way of your knowing about it until it is too late. It would be like walking through the jungle without any fear signal in the presence of a poisonous snake or other dangerous animals — while it might feel “nice” to be so relaxed,your body actually needs the stress response not only to remind you of danger but also to offer extra adrenaline (肾上腺素) for your heart and extra blood and oxygen for your arms and legs.

However,if the car alarm goes off at any time,someone just looks at the car with a bit of an attitude,and it becomes equally useless. Not only do we stop paying attention to it,but it begins to drive us and everyone around us becomes a little bit crazy. In the case of our bodies,walking around in a constant state of alarm also has some pretty alarming health consequences,which we will explore in greater depth in the next chapter.

B. We'11 achieve a sense of safety.

C. We'11 reach a perfect state of mind.

D. We'11 fail to realize the possible danger.

4. What's the purpose of giving the example of walking through the Jungle in Paragraph 4?
