 How healthy are you? Your best guess might be pretty accurate: Researchers found that people who gave their health a positive rating1 were less likely to fall ill or die over the next 30 years than were those who thought they weren’t as healthy. The work is in the journal

 
Public Library of Science ONE. 
 
More than 8,000 Swiss men and women rated their health on a scale ranging from very poor to excellent. Researchers tracked them 30 years later. Within the same age group, men who rated their health as “very poor” were greater than three times more likely to have died than were those who rated their health as “excellent.” For women, the odds2 almost doubled.
 
Nor was this trend limited to the extremes. The chances of dying went up from the “excellent” health group to the “good” one to the “fair” one, and kept increasing up to the “very poor” group.
 
And even after researchers took into account risk factors like smoking and medical history, the correlation3 between self-rated health and mortality remained. Maybe optimism4 also helps keep the doctor away.
 
Thanks for the minute for Scientific American 60 second Science, I am Sophie Bushwick.
