<i>Pessimists 'live longer'</i>

Finally the pessimists among us have something to be happy about.
Older people who are blighted by negative thoughts and fear for the future are more likely to live longer, a study has revealed.
Scientists found those with low expectations for a 'satisfying future' actually led healthier lives.
A study into 40,000 people found that being 'overly optimistic' in predicting a better future was associated with a greater risk of disability and death.
Lead author Frieder R Lang said: "Our findings revealed that being overly optimistic in predicting a better future was associated with a greater risk of disability and death within the following decade.
"Pessimism about the future may encourage people to live more carefully, taking health and safety precautions."
The research, based on data collected between 1993 and 2003, asked participants in three different age groups to rate how satisfied they were with their lives and how satisfied they thought they would be in five years.
The age groups were divided into 18 to 39, 40 to 64 and 65 and above.
They were interviewed again five years later, and their satisfaction levels were compared with their own predictions.
A total of 43 percent of the oldest group -- 65 years old and above -- had underestimated their future life satisfaction.
While 25 per cent had predicted their future happiness accurately, 32 percent had overestimated it.
Surprisingly, those in the oldest group who overestimated how happy they would be were found to have a 9.5 percent increase in reporting disabilities.
They had a ten percent increased risk of death, the analysis showed.
Older people, who tended to have a 'darker outlook' on the future, were said to be more realistic with their predictions and therefore were more likely to be accurate.
In contrast, the optimistic youngsters had the sunniest outlook, overestimating their success.
People who were 'overly optimistic' about the days ahead had a greater risk of disability or death within ten years.
The research, published by the American Psychological Association, also found those with higher income were more likely to be at greater risk of disability.
