People With Higher IQs Live Longer

From The Telegraph:

People with higher IQs are more likely to live into healthy old age, according to a study.

Unfortunately, those who do not perform so well in intelligence tests could suffer a higher risk of heart disease, fatal accidents and suicide.

The discovery was made after researchers looked into the medical records of one million Swedish army conscripts.

After taking into account whether they had grown up in a safer, more affluent environment, they established the connection between IQ and mortality.

One of the researchers, Dr David Batty, said the statistics showed "a strong link between cognitive ability and the risk of death."

He added: "People with higher IQ test scores tend to be less likely to smoke or drink alcohol heavily. They also eat better diets, and they are more physically active. So they have a range of better behaviours that may partly explain their lower mortality risk."
