Felicidade nos Genes

Pesquisadores de Edinburgh e do Queensland Institute for Medical Research na Australia dizem que felicidade esta nos genes: "What we found was that genes were responsible for certain personality traits which predisposed people to happiness. These traits included being someone who does not worry excessively, someone who is sociable and conscientious. It is this genetic link to personality, rather than a particular happiness gene pumping a happiness drug into the brain, which is partly responsible for our levels of happiness."
