When love feels hard, it’s easy to forget why we chose it in the first place. But remembering why we love—and what drives our need for connection—is often what helps us stay grounded. In this episode, Julie and Yue sit down with evolutionary anthropologist Dr. Anna Machin to explore what biology, psychology, and evolution can teach us about the most deeply human experience we have. Drawing from two decades of research, Dr. Machin reveals how our earliest attachments, neurochemical patterns, and evolutionary instincts shape how we love, who we choose, and why connection is so essential to our wellbeing. 

In this episode, you’ll learn:

How Evolution and Early Attachment Form Your Blueprint for Love

How Brain Chemistry Drives Attraction, Bonding, and Long-Term Connection

How Different Forms of Love—Romantic, Familial, Queer, Platonic, Polyamorous—Function in the Brain

Why Love Can Feel Addictive—and the Psychology Behind Coercive or Unhealthy Dynamics

How to Make More Conscious, Intentional Choices in How You Love

Why Love Is the Single Most Important Factor in Human Health and Meaning
