The study found people living in Denmark had the longest form of the gene, and as a result were found to be among the happiest nations in the world The French are often accused of being grumpy and dismissive. But Britons and Americans are also hardwired to be miserable, scientists claim. Despite stable governments and good economies, those living in the UK and US will never be as happy as people in other nations, because they are simply born more miserable. They are genetically programmed to be less cheerful than the Danes, for example, who top the list of the happiest nation. And scientists at the University of Warwick discovered it all comes down to a gene which regulates levels of the hormone serotonin in the brain. Short forms of the gene inhibit levels of the hormone, which can invoke depression. Meanwhile those with longer forms of the gene are more likely to be happier, as a result of higher levels of serotonin in the body. Researchers discovered people from Denmark have the longest form of the gene, and as such topped the happiness chart. But Professor Andrew Oswald said it could be worse, we could be French - the nation with one of the shortest forms of the gene, which may explain their reputation for being grumpy. Annual tables of national happiness ratings, compiled by organisations across the world, tend to rank Denmark at the top, along with nations including Panama and Vietnam. |
