Recent research shows that several personality traits predict who will enjoy health into their 80s and beyond. According to some studies, the link between personality and longevity is as strong as intelligence or how much money you have, both of which are correlated with longer lifespans.
People who are conscientious—organized and responsible—tend to live longer. “It’s probably the best silver bullet we can hope for,” said Nicholas Turiano, a psychology professor at West Virginia University. Being conscientious is a “resilience factor” that may help some individuals overcome major risks to health, such as living in poverty, said Turiano.
Many conscientious people are diligent about exercise and nutrition. They also seem to have better coping strategies for stressful situations, said Turiano, leading to less inflammation, which in turn slows down aging.

Another good quality for longevity is being purposeful, or having a direction in life with clear goals that energize you. Those who say that they have a life purpose recover faster from aggravations such as viewing pictures of pollution and other disturbing scenes. They also tend to have more brain volume in an area of the brain that’s linked to self-awareness and decision-making.
