(Newser) – Why some people get steamed while others stay cool depends on which version of a certain gene they carry, the Daily Telegraph reports. German scientists isolated a gene that affects dopamine levels. In a study, people with the least common variation showed little anger. Those with the other two mutations "are not able to control their feelings." Which could be a good thing: Aggression helps you get ahead in life, the researchers suggest.
