Scientists at the Vrije Universiteit Amsterdam have found three genetic variants for happiness, in a study published in the journal Nature Genetics.
Professors Meike Bartels and Philipp Koellinger conducted a large-scale international study with over 298,000 people and also found genetic differences in symptoms of depression and eleven parts of the human genome that could explain varying degrees of neurosis.
The genes for happiness were related to the central nervous system, adrenal glands and pancreas.
