Passage 2

According to researchers at University College London, human beings are naturally optimistic creatures.

It is ail in the brain，they say.（4）A study suggests it is very efficient at processing good news:（研究发现，人类的大脑在处理好消息时效率很高。)about 80% of people have a tendency to see the glass as half-full, not half-empty, even if they don't consider themselves to be optimists.（5）The good news is that this brings a health benefit. Being upbeat and having a positive outlook on life reduces anxiety.（拥有积极的人生观可以帮助人们减少焦虑，从而对身体健康有好处。）（6）study of nearly! 100,000 women showed a lower risk of death from heart disease amongst optimists.（一项针对10万女性的研究发现，乐观主义者死于心脏病的风险较低。）

But there are pitfalls to always having an upbeat attitude. The authors of the study point out the 2008 financial crisis may have been caused by analysts overestimating their assets，performance even in the face of clear evidence to the contrary.

There are personal health risks, too. Dr. Tali Sharot, lead researcher, said, "‘ Smoking Kills’messages don't work as people think their chances of cancer are low. There's a very fundamental bias in the brain."

But, as they say, very cloud has a silver lining. Even if seeing the world through rose-tinted glasses poses a risk to our health, it's not something that is likely to cause us to lose sleep.

Let's just keep our chins up and keep smiling!
