OLDER people who look on the darker side of life tend to live longer than optimists, who in turn face an increased risk of illness and mortality, a new study by a German research institute has found.
Researchers in Germany and Switzerland found older people who believe their life satisfaction will be above average in future face a 10 per cent higher mortality risk or are more likely to develop physical health problems, the DIW think-tank said.
"It is possible that a pessimistic outlook leads elderly people to look after themselves and their health better and take greater precautions against risks," said one of the researchers, Frieder Lang.
"It seems that older people who have a low expectation of how contented they will be in future lead longer and healthier lives than those who believe their future is rosy," DIW said.
The study was conducted by a team from the Friedrich Alexander University of Erlangen-Nuernberg, the Berlin-based DIW as well as Humboldt University in Berlin and the University of Zurich.
They analysed long-term data compiled between 1993 and 2003 where the same people belonging to three different age groups were asked every year to assess their current level of life satisfaction and how contented they expected to be in five years.
Over the 10-year period the researchers checked with each participant six times whether their expected level of satisfaction tallied with reality five years on.
Results showed 25 per cent of older participants realistically estimated their future contentment, while around 43 per cent underestimated it and 32 per cent overestimated, the DIW said.
Young adults mostly had an unrealistically rosy view of their future while middle-aged people were largely spot on, it said.
