Women are happier as compared to men, say American scientists in their recent findings. Researchers at the University of South Florida recently ran a study in which they noticed the presence of more happiness genes in women's brain than their opposition. They claim that the entire game of happiness and sadness in human beings is being played by these genes.

The genes in talks is known as 'MAOA', which researchers believe make good effect upon the levels of feel-good chemicals in the brain, which are further responsible for all the fluctuations that occur in the moods of both men as well as women.

They explained that the MAOA genes are present in two variations, a highly active one and a comparatively lesser active one. For which, approx 350+ men and women were questioned by the researchers during their study about how happy they were followed with the collection of their saliva sample that was further tested for their DNA.

They found that women, who showed presence of the less active type, were happier than others, but the ones, who had two copies of the 'happy' type of MAOA, were happiest among all the participants. Declared results revealed 59 percent women with one copy genes, 17 percent with two but among men only one in four lacked the happiness gene.
