These two chapters focused on how conscientiousness is the best predictor of longevity, not sociability. There were 3 reasons behind this: conscientious people are less likely to engage in risky behaviors, are less prone to diseases, and set themselves up for success. All these reasons were extremely interesting because it showed that some of who you will be is already who you are. The chapter also discussed how people can change over time, so this is not necessarily the case.
I really enjoyed the section about sociability because when I was a child, I was very shy and extremely introverted. It was nice to see that that’s not necessarily a bad thing and helped me to see how I’ve changed overtime. I really enjoyed the interactive pieces of these chapters too to help me assess myself and how I can improve to achieve maximum longevity.
