What if it was enough to take life on the bright side to live longer? In any case, this is what a study published in the Journal of Gerontology and relayed by SHE, which reveals that being optimistic would extend our life expectancy by a few years. This quality, which is far from being given to everyone, makes it possible to face the most distressing and stressful situations of daily life in a more peaceful way with more self-control. Optimists have this ability to succeed in minimizing their dose of stress, even going beyond it, and this is how they manage to preserve their health.
