Mark and Michael sit down with Derek to discuss risk, backcountry skiing, cortisol response, IEDs, getting blown up overseas, how great V-hull, sloped armor faces are, combat-related PTSD, counseling, and the utility of discussion and EMDR to treat and assimilate the aftermath of acute traumatic events, as well as the power of small group, honest, open conversation, expressing vulnerability, and the self-awareness required to remain (relatively) safe in high-risk situations. Eventually they discuss National Guard involvement during protests at Lafayette Park in Washington DC and what might be learned from that and similar events if civil, open discussion were possible in this era. Towards the end they talk over the practice of physical training — as a vehicle to tune one's psychology and emotion — and agree that doing so appears fix everything.
