In a study published in the journal Aging on May 21, researchers surveyed people who were over the age of 95 and found that most of them had positive personality traits, making them upbeat and relaxed about life. That suggests personality traits such optimism could be part of the longevity genes mix, they said.
For this particular study, 243 Ashkenazi (Eastern European) Jews over the age of 95 were given a 98-point questionnaire that specifically looked at personality traits. Three-fourths of the group were women, and the average age was 97.6 years old. Since they were all the same ethnicity, it allowed researchers to compare results from a similar genetic pool.
What scientists found out was that many of the near-centenarians were optimistic, easygoing, liked to laughed and were outgoing than introverted. They also were more likely to express their emotions, rather than keeping it all inside.
The good news is that if you aren’t exactly that ray of sunshine, you still have time to change. Barzilai said that some evidence shows that people can change their attitudes between the ages of 70 to 100, and it isn’t exactly know if the subjects were always optimistic their entire lives.
