Road rage gene?

People who don’t control their aggressive impulses could have the “road rage” gene, according to Geneway genetic expert Christa North.

“This gene helps keep the neurotransmitters dopamine and serotonin in balance,” she said. Without this balance, people tend to be less controlled in and after a stressful event.

“On a rugby field this could work. You don’t want a wuss,” she said. “But a couple of years ago a guy killed somebody and got some time off his sentence because of this gene.”
