A study authored by Christopher Nave, a doctoral candidate at the University of California, says that our personalities stay pretty much the same from early childhood all the way through old age
. From the article: "Using data from a 1960s study of approximately 2,400 ethnically diverse schoolchildren (grades 1 - 6) in Hawaii, researchers compared teacher personality ratings of the students with videotaped interviews of 144 of those individuals 40 years later. They examined four personality attributes - talkativeness (called verbal fluency), adaptability (cope well with new situations), impulsiveness and self-minimizing behavior (essentially being humble to the point of minimizing one's importance)." This must explain my overriding need to be first captain when we pick kickball teams at the office.
