Where does love originate?  The heart or the brain?  Or is it something that we attract from outside of ourselves?  Science tells us that all emotions including love originates in the brain. We feel the passions of love because our brains contain specific neurochemicals and peptides that create those loving feelings in us. There is never a conflict between the heart and the brain but rather between different parts of the brain, parts that specialize in rational thought, such as long-term planning, and parts that give our lives emotional energy.  Lends support to the old term “head over heels”. 😉
