According to some scientific studies, the ability to see life on the right or wrong side is linked to the gene of happiness. This gene regulates in particular the circulation of serotonin the hormone of good humour.
People with the long form of this gene are more predisposed to happiness than those with the short form. this genetic heredity plays for 50% in our ability to be happy.

Other elements affect our happiness.
External factors and living conditions, such as family, professional, financial, health, etc.
An important part of our ability to find happiness depends on ourselves.
