In this episode, I am joined by Dr. Shireen Fatemi, a distinguished endocrinologist whose vision of medicine extends far beyond lab values and prescriptions. Raised in a family that blended science with intuition, Dr. Fatemi brings a rare voice to the conversation about the body’s most mysterious messengers: our hormones. Together, we explore how endocrinology illuminates not just physical health, but also mood, memory, and identity. From the impact of cortisol and circadian rhythm, to the cultural overreliance on medication, to the uncharted mysteries of the pineal gland, Dr. Fatemi challenges us to see the human being as both rational and hormonal - balanced, interwoven, and profoundly alive. This is not just a medical conversation. It is a meditation on how hidden systems guide our choices, shape our stages of life, and even open questions of spirit and selfhood.
