Une récente étude menée en Allemagne a conclu que la colère est pour moitié d'origine génétique (gêne DARPP-32).
La prochaine que vous vous retrouvez emporté par la colère, défendez-vous en disant : "Je suis innocent, mes parents sont les vrais coupables!"
Anger is in the genes
Isolation of a gene called DARPP-32 helps explain why some people fly into a rage at the slightest provocation, while others can remain calm.
More than 800 people were asked to fill in a questionnaire designed to study how they handle anger.
The German researchers also administered a DNA test to determine which of three versions of the DARPP-32 gene people were carrying.
The gene affects levels of dopamine, a brain chemical linked to anger and aggression.
Those who had the "TT" or "TC" versions of the gene portrayed significantly more anger than those with the "CC" version.
The study, from the University of Bonn, also found that those who display more anger have less grey matter in the amygdala, a part of the brain that helps keep our emotions balanced.
Martin Reuter, one of the researchers, who is a TC, said: "In other words, they are not able to control their feelings as well as those without the mutation.
"I am not an angry person but I can get angry if it is important."
TT and TC versions are much more common in Western populations, with the researchers suggesting that demonstrations of anger can help people get ahead in life.
"High degrees of anger are of course of low social desirability but a certain amount of dominance-related behaviour helps to assert position in a social hierarchy," the researchers added.
Reporting in the journal Behavioural Brain Research, they added that genetics only account for around half of our disposition towards anger, while DARPP-32 is one of several genes involved.
Earlier this year it was reported that showing anger rather than repressing emotions is the key to a successful professional and personal life. The study by the Harvard Study of Adult Development found those who keep a check on their frustrations are at least three times more likely to admit they have disappointing personal lives and have hit a glass ceiling in their career.
