<em>Genetics' influence on the happiness</em> of a person has long been studied. Some people say that the genes of a person affects the person's mood. For example, "5-HTTLPR" is a gene that is regarded to be connected to depression. This is why it is called<u> "the depression gene."</u> It is also associated with sleep disorders like "insomnia." When someone has trouble sleeping, it disrupts his way of life thereby affecting his happiness.
On the contrary, the genes exhibit themselves according to external environments.
