Hilary Tindle from the University of Pittsburgh School of Medicine in Pennsylvania was the lead author of the report. She said the study confirmed earlier research that linked optimistic feelings to longer life.

　　The researchers also gathered information about people's education, financial earnings, physical activity and use of alcohol or cigarettes. Independent of those things, the findings still showed that optimists had less chance of dying during the eight­year period.

　　Some women who answered the questions were found to be hostile(敌对的), or highly untrusting of others. These women were sixteen percent more likely to die than the others. They also were twenty­three percent more likely to die of cancer. The study also found that women who were not optimistic were more likely to smoke and have high blood pressure or diabetes(糖尿病). They were also more likely not to exercise.

　　Professor Tindle says the study did not confirm whether optimism leads to healthier choices, or if it actually affects a person's physical health. She also says the study does not prove that negative emotions or distrust lead to bad health effects and shorter life. Yet there does appear to be a link that calls for more research.

　　文章大意：研究人员对美国十万名老年妇女进行了为期八年的跟踪研究，结果发现情绪乐观的人患病的几率较其他人低，死亡率也低。相反，对别人敌对或不信任的人发病率和死亡率都较高。但是人的情绪与健康和寿命之间的关系还需要进一步的研究。
