Optimism and the Odds of Reaching Eighty-Five
In nearly 70,000 women and over 1,400 men, the most optimistic lived around 11 to 15 per cent longer and were markedly more likely to reach age 85.

Most longevity research chases biological markers. This study asked whether a psychological outlook, optimism, independently predicts a longer life, and found that it does. It drew on two long-running cohorts: 69,744 women from the Nurses' Health Study, followed for a decade, and 1,429 men from the Veterans Affairs Normative Aging Study, followed for three. Optimism, defined as the generalised expectation that good things will happen, was measured with validated scales at baseline. Those in the highest optimism group lived on average 11 to 15 per cent longer than those in the lowest, and had about 1.5 times the odds, for women, of achieving what the authors called exceptional longevity, meaning survival to 85 or beyond. What makes the finding notable is what it survived: the association held after adjusting for education, marital status, social ties, chronic health conditions and even depression, and only partly weakened when health behaviours such as smoking and diet were taken into account, suggesting optimism works both through and beyond healthier habits. Where the evidence stops: this is observational, the main female cohort was largely white and highly educated, and optimism was measured once, so the study shows a robust association rather than proving that becoming more optimistic will extend a given life. Its value is in establishing a positive psychological resource, not merely the absence of distress, as a credible correlate of a long life, and optimism is more trainable than most people assume.
