You know you do it. We all do! Starting around mid-November, Silent Night, Joy to the World, Have Yourself a Merry Little Christmas all start creeping into our heads. We sing these Holiday tunes in the shower, in the car, or doing dishes. They just creep up without knowing it…but do we mind? Not usually because they make us feel SOOOO good.
Why do they have this power? Well…it is all science.
