What if the same symptoms we see in combat veterans — the broken sleep, the irritability, the brain fog — were already quietly spreading through the healthiest, highest-performing people you know?
In this episode of Health Longevity Secrets, Robert Lufkin MD sits down with Neil Markey — a former US Army Special Operations captain from the 75th Ranger Regiment turned McKinsey consultant, now the co-founder and CEO of Beckley Retreats and a Harvard Chan School student researching psychedelic-assisted integrated health. Neil walks us through his own journey out of post-combat trauma, the neuroscience of why psilocybin opens a rare window of neuroplasticity in the adult brain, and why he believes this work belongs upstream as preventative medicine for the well.

KEY TAKEAWAYS: • Psilocybin opens a measurable window of neuroplasticity in the adult brain • Set, setting, and integration determine outcomes far more than the compound itself • Psilocybin is non-toxic with low incident rates when used in controlled environments • The "betterment of the well" use case may be as transformative as clinical treatment • Oregon and Colorado have legalized supervised use; New Mexico and Massachusetts are next • Chronic stress in high-performers replicates many PTSD-like symptoms • Awe, empathy, and connection are measurable outcomes — and they beat burnout
