What if calm isn't something you have to earn—but something your nervous system already knows how to access? In this conversation, I sit down with Dr. David Rabin, neuroscientist, psychiatrist, and co-founder of Apollo, to explore how decades of research into chronic stress, PTSD, neuroscience, and human performance led him to build one of the first wearables designed to actively improve nervous system regulation rather than simply measure it. We unpack the science behind stress, why so many of us have become disconnected from our body's natural state of safety, and how technology can either contribute to burnout or help us reclaim calm. We also discuss the evolution of wearables, what founders can learn about resilience, and why our perspective toward stress may be one of the most powerful health interventions available.
