FRIDAY, March 7 (HealthDay News) -- The right genetic mix might lead to a lifetime of happiness, a new British study suggests.
"While it was known that around half the differences in happiness are related to genes, what we found was that those happiness-related genes are genes for personality, namely for being extroverted, emotionally stable and conscientious," said co-researcher Tim Bates, from the School of Philosophy, Psychology and Language Sciences at the University of Edinburgh.

Because personality is relatively stable, this new research helps solve what was otherwise a real puzzle, namely why people tend to show stable differences in happiness, Bates said.
"It turns out that if we want to understand happiness, we will need to understand personality," Bates said. "An important implication is that personality traits of being outgoing, calm and reliable provide a resource, we called it affective reserve, that drives future happiness," he said.
In the study, Bates' team collected personality and happiness information on 973 twin pairs. The researchers were able to identify evidence for genes tied to certain personality traits and genes that predispose people to happiness.
The researchers found that people who don't worry excessively and are sociable and conscientious tend to be happier, according to the report in the March issue of Psychological Science.
While happiness has a genetic component, about 50 percent of the difference in happiness between people results from relationships, physical health, and careers, Bates noted.
However, those lucky enough to have the right gene mix appear to have an extra supply of happiness that they can use when times are tough, the researchers reported.
"If people want to raise their own levels of well-being, our best advice is that they practice the kinds of behaviors that characterize calm, conscientious, extroverts," Bates said.
