A new health report says that having good friends in your old age helps you live longer. The report also says that having close friends may be more important than having close family ties. Researchers interviewed 1,500 Australians over the age of 70 about their social and family ties. The results suggest that people with close friendships were 22 per cent more likely to live longer. The researchers said this is because of the positive effects on the body of social activity and recreation.
The researchers analyzed data from an Australian study, which began in 1992. The 10-year-long study measured how behavioral, economic, environmental and social factors affected the health of 70-year-olds. The senior citizens were monitored annually for four years and then at three-yearly intervals. The team found that those with the strongest network of friends were less likely to die by the end of the ten-year period. The message is to keep in touch if you want to live longer.
