In a culture that often reduces love to romance, Geena Davis helps us explore the science of love across the lifespan—revealing how our bonds with parents, friends, partners, and communities shape our health, happiness, and survival.

Summary: Love is commonly understood as a feeling, yet scientific research increasingly points to its role as a core biological drive. In this episode of The Science of Love, we explore how love is expressed through caregiving, friendship, romantic attachment, and shared experience, and how these connections leave measurable effects on the brain, body, and even the microbiome.
