Lifespan May Be Linked To Personality

Are you and introvert or an extrovert? If you answered extrovert, you are more likely to live longer. According to a study to be published in the July issue of the journal Brain, Behavior and Immunity:

"Our ability to withstand stress-related, inflammatory diseases may be associated, not just with our race and sex, but with our personality as well... Especially in aging women, low levels of the personality trait extroversion may signal that blood levels of a key inflammatory molecule have crossed over a threshold linked to a doubling of risk of death within five years."
