“Most people think love comes from the heart or soul. The heart simply pumps blood, so love can't be created there. Where is the center for what appears to be a person's soul? The Brain. And what is created there, Jilly? That's right--dopamine. What does dopamine do? Creates feelings of love and euphoria. How do we get our brains to create more? Drugs, massage, and/or sex. Boil it down and it's all just dopamine.”
