Hey, it's an inventor's market, and there's a shortage of great ideas. They have found that that children with higher IQs are more likely to live longer.
Nobody is sure why more intelligent people are likely to live longer.
They then followed up to see who was still alive in 1997. It was found that both men and women with higher IQ scores as children were much more likely to be alive 60 years later. The researchers took an average IQ in the group as 100. It is thought that IQ is largely inherited. Environmental influences are also thought to play a role, but the influence of the family wanes rapidly past the age of seven or eight.
