Fast driver, fast life: Genetics and everyday behaviour reflected in risky driving

A new long-term psychological study of drivers has found an association between driving convictions, accidents and everyday behaviour such as eating junk food or alcohol consumption. The researchers have also uncovered evidence that this relationship is associated with genetic variation in serotonin metabolism – the same neurotransmitter targeted by many antidepressants. This suggests that risky behaviour in driving and in life may have a common psychological basis.
