1、 研究：快乐可以遗传A study of nearly 1000 pairs of identical and non-identical twins found genes control half the personality traits that make people happy while factors such as relationships, health and careers are responsible for the rest of our well-being.“We found that around half the differences in happ
2、iness were genetic,“ said Tim Bates, a researcher at the University of Edinburgh who led the study. “It is really quite surprising.“The researchers asked the volunteers ranging in age from 25 to 75 a series of questions about their personality, how much they worried and how satisfied they were with
3、their lives.Because identical twins share the same genes and fraternal twins do not, the researchers could identify common genes that result in certain personality traits and predispose people to happiness.People who are sociable, active, stable, hardworking and conscientious tend to be happier, the
4、 researchers reported in the journal Psychological Science.“What this study showed was that the identical twins in a family were very similar in personality and in well-being, and by contrast, the fraternal twins were only around half as similar,“ Bates said. “That strongly implicates genes.“The fin
5、dings are an important piece of the puzzle for researchers trying to better understand depression and what makes different people happy or unhappy, Bates said.People with positive inherited personality traits may, in effect, also have a reserve of happiness to draw on in stressful times, he said.“An
6、 important implication is that personality traits of being outgoing, calm and reliable provide a resource, we called it affective reserve, that drives future happiness“ Bates said.欢乐买不到，但英国和澳大利亚的讨论人员称，欢乐至少可以遗传得到。一项对近千对同卵及异卵双胞胎开展的讨论发觉，在欢乐的性格特征中，有一半是由基因掌握的，而另一局部则受到人际关系、安康、职业等因素的影响。讨论负责人、爱丁堡大学的蒂姆贝茨说：“我
7、们发觉，讨论对象在欢乐方面的差异约有一半受到遗传基因的影响。这个结果实在令人惊异。”讨论人员向年龄在25岁至75岁之间的志愿者提出了一系列问题，问题涉及他们的性格特点、焦虑程度以及对目前生活的满足度。由于同卵双生的双胞胎基因完全一样，而异卵双胞胎不完全一样，所以讨论人员可以辨别出打算某些性格特征及使人简单欢乐的共同基因。讨论报告在心理科学期刊上发表。讨论人员指出，擅长交际、活泼、踏实、勤奋、有责任心的人更加欢乐。贝茨说：“该讨论说明，同卵双胞胎的性格特征和欢乐程度非常相像，然而，异卵双胞胎仅有约50%的相像度。这充分说明白基因的作用。”贝茨说，讨论人员始终在努力查找有关“人为什么会郁闷”的更为合理的解释及影响不同的人欢乐与否的因素，这一发觉无疑为这一难题供应了一个重要解释。他说，具有乐观遗传性格特征的人实际上同时拥有一种“欢乐储藏”，供他们在郁闷的时候“支取”。贝茨说：“这说明白很重要的一点，外向、冷静和牢靠的性格特点能形成一种“情感储藏”，为将来的欢乐供应保障。”
