Fluctuating hormones are often due to the reason why most womenare much easier to complain, grumble and be irritable. In fact it’s actually the type of genetically inherited.

Scientific research shows that women are genetically programmed to be irritable and aggressive. This is partly because women have a serotonin receptor gene, called the 2C gene. The good news, not all women inherit the gene.

The hormone serotonin is associated with feelings of anger andaggression in both humans and animals. Studies have shown anincrease in activity of serotonin associated with reducedaggressive behavior.

Irritable attitude was a marker of a number of health conditions,which have high blood pressure and heart disease are.

Although they are often irritable, stubborn, and irritable, it appears that these qualities are valued as a form of self-confidence and areusually owned by people who have a strong personality. Therefore, people with a stubbornness that is considered attractive to the opposite sex.

But what if the gene is inherited irritable can not be changed? Of course. Since environmental factors have the ability to control, influence, even alter the genetic factors.
