Happiness more than genetic

The idea that happiness is a genetic trait influenced by early life experiences has been challenged by new research from Germany. It found feelings of happiness and well-being respond to external factors such as healthy lifestyle, religion and working hours. The study appears this week in the Proceedings of the National Academy of Sciences. Lead author, associate professor Bruce Headey of the Melbourne Institute at the University of Melbourne, says the findings suggest genes only account for around 50 per cent of well-being, with external factors accounting for the rest.

While there is no doubt that many people seem more predisposed to being either happy or depressed, it is reasonable to assume that external factors play a major role in somebody's overall mood. As is the case with all elements of human existence, our lives are a complex combination of genetics and interactions with the world we live in. Ultimately we are either the beneficiaries or victims of so many things beyond our control. The influence of genetics and our day-to-day world profoundly impact who we are and how we feel.
