Genetic Happiness

The 5-HTT gene affects transportation of serotonin in neurons, according to a study reported in The Telegraph.The researchers found that 69% of people who had two copies of the gene said they were either satisfied or very satisfied with their life as a whole. This fell to 38% those who had no copy of the gene.The study is published today (FRI) in the Journal of Human Genetics; author De Neve, said: "It has long been suspected that this gene plays a role in mental health but this is the first study to show that it is instrumental in shaping our individual happiness levels.Of course, our well-being isn’t determined by this one gene – other genes and especially experience throughout the course of life will continue to explain the majority of variation in individual happiness. But this finding helps to explain why we each have a unique baseline level of happiness and why some people tend to be naturally happier than others, and that’s in no small part due to our individual genetic make-up."
