Reasons to be cheerful: optimists live longer, says study

Those with a positive attitude to life may lower their anxiety levels by avoiding arguments

People who have a rosy outlook on the world may live healthier, longer lives because they have fewer stressful events to cope with, new research suggests.

Scientists found that while optimists reacted to, and recovered from, stressful situations in much the same way as pessimists, the optimists fared better emotionally because they had fewer stressful events in their daily lives.
