80% of people are optimists even if they dont label themselves as such.
When people hear positive news, all people have more activity in the brain's frontal lobes, which are associated with processing errors. With negative news, the most optimistic people had the least activity in the frontal loves, and the least optimistic had the most.
Optimistic people have a lower risk of heart disease and a lower death rate, but they also underestimate risks.
