Crimes such as assault, murder, kidnapping and rape. They are also a third more likely to suffer unintentional injuries from causes such as traffic accidents.
Scientists speculate this is because they are more fearless (or perhaps psychopathic?)
They draw these conclusions based on a study of 700,000 Swedish men born between 1958 and 1991 who had their resting heartbeat measured when conscripted for national service.
They followed the men for up to 30 years and found a strong link between their resting heart rate and whether or not they had a criminal record or had been involved in accidents.
The findings pose a conundrum “No one wants to blame individuals for the violence they endure. They can hardly be blamed for having a low resting heart rate that puts them at risk” said psychologist Professor Raine commenting on the study.
“Yet if we accept this logic, should the legal system accept low resting heart rate as a mitigating factor for the commission of serious violence?”
Perhaps more importantly girls; if your man’s heartbeat isn’t racing when you’re together it might not just be that he’s not into you!
