Happy? Thank Your Genes
In one of the largest studies ever published on the genes associated with human behavior, an international team of more than 190 researchers in 17 countries has — in the words of one of the researchers — "found three genetic variants associated with subjective well-being [or] how happy a person thinks or feels about his or her life."
Published in the journal Nature, the study analyzed pooled genomic data from many other studies involving hundreds of thousands of people in a search for genetic variants involved with feelings ranging from depression and neuroticism to well-being.
Studies of the root causes of happiness, it turns out, could be enormously helpful in research across myriad branches of medicine, as a growing body of evidence points to the central role that emotional well-being plays in both our mental and physical health.
