Stress influence on lifespan

Stress influence on lifespan could be estimated using this article:
https://pubmed.ncbi.nlm.nih.gov/33923661
3.6% of the most dissatisfied with their marriage people had RR 1.21 (1.04 - 1.41) comparing to 43% most satisfied.
That corresponds to 1.8 (0.4 - 3.2) years of lifespan decrease.

33% happiest people have RR 0.84 (though big CI) comparing to people with average happiness level.
Adjusted for really many factors. RR 0.84 => 1.6 years of life difference.
The questions they were asked were how often in the past week have you (1) felt happy (2) enjoyed life (3) felt hope about future
2 points were given for "Often", 1 point for "Sometimes", 0 points for "Never or rarely"
So try to be happy and enjoy life at least once a day!
