Those who are interested in psychology, know the “Big Five” personality traits: agreeableness, conscientiousness, neuroticism, openness and extraversion. Researchers of a recent study were curious whether 3 of these personality traits (conscientiousness, neuroticism and extraversion) somehow are related to our brain functioning later in life.

You probably already know that people who are more conscientious (responsible, organized and capable of self-control), tend to live longer and have a 40% decreased risk of death compared to the less conscientious people. But why that is that and how that happens was not clear … until now.
