Genes Define Level Of Happiness
Happiness is found to depend not only upon lifestyle, but also genetic background.
Edinburgh University scientists conducted a research to estimate how genes affect happiness. They studies 900 pairs of identical and fraternal twins. Identical twins are genetically the same, fraternal twins are not.
Twins were chosen with the following types of character: people who never worry, who are sociable and who are conscientious. These three characters are already proven in previous studies to have the most common role in happiness.
The study found that 50% of happiness feeling is initially defined by genes. The other 50% depend upon lifestyle, career, and relationships.
The research, however, doesn't necessarily mean that those with weak genetic background will not have chances to be happy. There are lots of psychologically proven ways to improve self-esteem, well-being and happiness. Particularly, scientists suggest keeping a personal notebook with daily writing about owner's impressions and mood as a common way of mood improvement.
Dr Alexander Weiss from Edinburgh's School of Philosophy, Psychology and Language Sciences said: "Together with life and liberty, the pursuit of happiness is a core human desire. Although happiness is subject to a wide range of external influences we have found there is a heritable component of happiness which can be entirely explained by genetic architecture of personality."
