To conclude, the research of Friedman, Kern, and Reynolds (2010) suggests that although neuroticism tend to cause negative or lower subjective well-being, physical health was still considered the greatest predictor for a person’s longevity both for men and women.
It is also worth noting that neuroticism does not predict later life physical health as well as longevity. According to Taga, Friedman, and Martin (2009), neuroticism may as well be beneficial to people when faced by challenges in life, and people high on neuroticism tend to heavily evaluate and plan their actions compared to others. Furthermore, even though extraversion predicted healthy aging within the social competence aspect, it was found not relevant to health and longevity. In comparing men and women in terms of personality—health relationship, this study found many differences. As above mentioned, women who are high on conscientiousness and low on neuroticism were expected to live longer lives and tend to be healthier physically, socially, and subjectively as they get older. When it comes to men, the research found the relationship between personality, well-being, and longevity to be more complex to determine, suggesting that other psychosocial factors may be considered.
