A life-giving, relational “dietary supplement” for increased connection, resilience, and joy in any married couple’s relationship! Marcus and Chris have made the brain science easy to “swallow” and the dosing very doable. Warning: The exercises laid out in this book are known to cause increased levels of oxytocin, dopamine, and serotonin in those married couples who practice them. Greater intimacy, more satisfying rest, more frequent laughter and joy are the most common side effects. Be aware that joy, in full strength, is extremely contagious and habit-forming.
