The Benefits of Being Conscientious

Conscientiousness is a characteristic that leads to a longer and healthier life. This is evident from the Terman Study that shows how conscientious behavior can have a positive impact on life. Conscientious people tend to lead healthy and risk-free lives, have higher levels of serotonin which keeps them emotionally stable, and finally, have healthier personal and professional relationships. These reasons underline why being conscientious is a valuable characteristic to possess.

Laughter alone won’t lead to a long life

A study on the Terman participants found that being cheerful doesn’t guarantee a long life. The key factors for happiness and longevity are having strong social connections, a fulfilling career, and interesting hobbies. Following research-backed practices, such as being physically active, practicing gratitude, and helping others, can positively impact both happiness and longevity. The best results come from naturally incorporating these activities into a satisfying and healthy lifestyle that prioritizes social bonds.

Divorce, Childhood, and Longevity

The children of divorced parents are likely to die earlier than those whose parents stay together, according to research. Divorce exposes these children to stress, which makes them more prone to unhealthy behaviors such as smoking and drinking. The likelihood of such children experiencing another divorce in adulthood is also high, leading them to experience a life of loneliness and social isolation. However, the study also found that resilience is a major contributing factor in ensuring such children live long and healthy lives. Successful resilience in young adulthood has been linked to being content with one’s life, achieving potential, and the ability to overcome difficult situations despite their background.

The Surprising Relation between Marriage and Life Expectancy

A study has shown that men who stay married tend to live longer than those who are single or divorced. Women, on the other hand, only have a longer life expectancy if they are in a happy marriage. Divorced women who stayed single lived almost as long as those who stayed married. The study suggests that wives provide life-saving help or encourage healthier habits in their husbands, and that divorced men who remarried did not experience the same benefits. Divorce is also a big social stressor that can trigger harmful habits. Women do not need to get married to increase their life expectancy, but a happy marriage can help them thrive and live longer.
