#143 - The Science of Love, Desire, and Sex
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Matt examines the neurobiology of love, defining it as a reward system rather than just an emotion. He breaks love into three systems: lust (hormones), attraction (dopamine), and attachment (oxytocin). Using brain scans and prairie vole studies, he explains why romance feels like "madness" and why love is neurologically "blind."
Discussing long-term passion, Matt notes that some couples sustain dopamine-rich attraction for decades. He details how intimacy regulates stress and how orgasms require the brain to "switch off" control. While biology drives us, Matt argues that humans can consciously choose to build deep, lasting bonds through vulnerability.
