The New York Times shows that old dogs can learn new tricks, especially in matters of love and marriage.
Tara Parker-Pope writes (excerpt):
Rather than visiting the same familiar haunts and dining with the same old friends, couples need to tailor their date nights around new and different activities that they both enjoy, says Arthur Aron, a professor of social psychology at the State University of New York at Stony Brook. The goal is to find ways to keep injecting novelty into the relationship. The activity can be as simple as trying a new restaurant or something a little more unusual or thrilling — like taking an art class or going to an amusement park.
The theory is based on brain science. New experiences activate the brain’s reward system, flooding it with dopamine and norepinephrine. These are the same brain circuits that are ignited in early romantic love, a time of exhilaration and obsessive thoughts about a new partner. (They are also the brain chemicals involved in drug addiction and obsessive-compulsive disorder.)
