Women's irritability is registered in the genes.

Woman's brain itself is largely prone to anxiety and depression, as well as mood swings.

fact that the happiness hormone, called serotonin, is made differently in men and women. Women have more receptors that respond to serotonin, which are also able to interact longer with the accumulated hormone without a new dose.

As a result, women are less prone to depression.

But such a large number of receptors contributes to deficiency of the hormone of happiness, as a result of the female brain undergoes a continuing need for it and eagerly pounces on each sector particle.

Hence the constant mood swings and irritability ... The men shrug their shoulders and call it a bad temper and women's logic.
