Is your wife a cheerful person? If yes, then you are more likely to lead a healthier and longer life as compared to those who have less happy partners, reveals a new study. The study, published in the journal Psychological Science, suggests that having a happy spouse not only leads to a long marriage but also a longer and healthier life.

"The data shows that spousal life satisfaction was associated with mortality, regardless of individuals' socioeconomic and demographic characteristics, or their physical health status," said study author Olga Stavrova, a researcher at Tilburg University in the Netherlands.
