Today's guest is Dr. David Smith, a physician & inventor who has spent 14 years studying nature's most impact-resistant creatures to solve traumatic brain injury. He's the creator of the FDA-authorized Q-Collar and revolutionary CO2 rebreather technology that could transform how we prevent brain injuries, treat sleep apnea, and manage altitude sickness. In this podcast we cover his groundbreaking "SLOSH Theory," why people die on Mount Everest, the controversial truth about CO2 levels, and how he brought a clinically brain-dead patient back to consciousness using CO2 therapy.
