Interestingly, despite all the argument for including it within future nosologies ofuncertainty about the epidemiology of happiness, psychiatric disorder.there is some evidence that it is unevenly distributed Historically, there have been two approachesamongst the social classes: individuals in the higher towards the definition of disease (15).
