According to a large-scale longitudinal study, people who are optimistic tended to live longer than those who are not, and it even increased the chances of ‘exceptional longevity’, the term used for people who live to be 85 or more.
The team split about 70,000 women into four equally sized groups, based on their scores for optimism. They then compared lifespan for the most optimistic with the least, taking into account factors including age, sex, race, education, depression and other health conditions present at the outset.
The results show the most optimistic group of women had a lifespan almost 15% longer than the least.
Similar results were seen in men, even though optimism was measured slightly differently. When the team compared the fifth of men boasting the highest optimism scores with the least optimistic, they found the most positive men had lifespans almost 11% longer.
