Do optimists really live longer?

A large cohort study finds that looking on the bright side does seem to extend life: Women's Health Initiative cohort

Patients with a ‘glass half full’ outlook appear to live about half a decade longer than their gloomier peers, US findings suggest.  

Optimists are also more likely to achieve “exceptional longevity” and live into their 90s compared with pessimists, the large population-based study shows.
