有些人天生就相信他们是自我生命的主宰，其他人则觉得他们受到命运的支配。一项新的研究发现这些感觉部分来自基因。
Psychologists have long known that people confident in their ability to control their destinies are more likely to adjust well to growing old than those who feel that they drifi on the currents offate.
心理学家早就知道有信心掌握自己命运的人比那些觉得自己是受命运摆布的人更能适应老化。
Two researchers who questioned hundreds of Swedish twins report that such confidence, or lack ofit, is partly genetic and partly drawn from experience.

The research was conducted at the Karolinska Institute-better known as the body that annually awards the Nobel Prue for medicine-by Nancy Pedersen of the hrstitute and Margaret Gatz, a professor of psychology at the University of Southem Califomia in Los Angeles.
