(PHYSorg.com Medicine & Health)

A huge happiness and positive thinking industry, estimated to be worth US$11 billion a year, has helped to create the fantasy that happiness is a realistic goal. Chasing the happiness dream is a very American concept, exported to the rest of the world through popular culture. Indeed, `the pursuit of happiness` is one of the US`s `unalienable rights.` Unfortunately, this has helped to create an expectation that real life stubbornly refuses to deliver.
