What if the goal of longevity isn’t simply living longer, but remaining strong, capable, mentally sharp, and engaged as you age?

In this episode of the Mark Divine Show, I sit down with Regan Archibald, founder of Ageless Future, to explore how personalized medicine, emerging therapies, and the fundamentals of human performance are changing the way we think about aging.

Regan shares how his own health challenges led him toward a more individualized approach to medicine and why he believes comprehensive diagnostics can reveal patterns that standard testing may overlook. We discuss the hidden health costs that can accompany high performance, including chronic stress, overtraining, poor recovery, and the tendency to keep pushing even when the body is signaling that something needs attention.

We also explore peptides and signaling medicine, hormone optimization, GLP-1 therapies, regenerative medicine, and MUSE cells. Throughout the conversation, we come back to an important point: emerging therapies don’t replace the fundamentals. Sleep, movement, nutrition, recovery, stress regulation, relationships, and mindset remain central to long-term health.

In this episode:

• Why high performance can carry hidden health costs
• Looking beyond standard bloodwork with comprehensive diagnostics
• Building a personalized health operating system
• Chronic stress, overtraining, and accelerated aging
• Why recovery becomes increasingly important with age
• How peptides work as signaling molecules
• Peptides versus hormone replacement
• What to understand about GLP-1 therapies
• The importance of lifestyle alongside medical interventions
• Regenerative medicine and emerging MUSE cell therapies
• Why relationships matter for longevity
• Building today for the health and performance you want ten years from now

Trauma doesn’t always look like someone falling apart. Sometimes it can hide behind achievement, relentless ambition, risk-taking, and the drive to keep doing more.

In this episode of the Mark Divine Show, I sit down with clinical psychologist Dr. Edith Shiro to explore post-traumatic growth and the possibility of becoming stronger, more aware, and more connected through the process of healing.

Dr. Shiro shares how her own family history shaped her understanding of generational trauma and explains why trauma is about more than the event itself. The resources we have, the relationships surrounding us, our sense of purpose, and the tools we’ve developed can all influence how we respond.

We also unpack her five-stage framework for post-traumatic growth, beginning with radical acceptance and moving through support, new narratives, integration, and ultimately greater wisdom and purpose. And we explore why high performers may need to look especially closely at what is driving their ambition when the outside world continues rewarding their success.

In this episode:

• How trauma can move through generations
• Why the event itself doesn’t tell the whole story
• Building resilience before adversity arrives
• Why healing happens through relationships
• Purpose and spirituality as protective factors
• Dr. Shiro’s five stages of post-traumatic growth
• Radical acceptance as the beginning of healing
• Creating a new narrative after trauma
• Why the body has to be part of trauma recovery
• Forgiveness without bypassing pain
• When high performance becomes a way of avoiding trauma
• Moving from survival toward growth, wisdom, and service

A concussion can affect far more than memory or concentration. It can change sleep, mood, physical function, personality, and even how someone experiences their own identity.

In this episode of the Mark Divine Show, I sit down with neurologist and concussion expert Dr. Teena Shetty to explore why brain injury requires a much more integrated approach to recovery.

Dr. Shetty explains why concussion should not simply be treated by waiting for symptoms to disappear. We discuss the role of sleep and circadian rhythm, exercise, nutrition, physical and vestibular therapy, psychological support, and caregivers in helping the brain recover.

We also explore repetitive and subconcussive impacts, why someone doesn’t necessarily have to lose consciousness to experience a concussion, and how symptoms such as anxiety, irritability, sadness, and personality changes can be connected to brain injury.

In this episode:

• Why concussion recovery requires an integrated approach
• The cognitive, physical, and emotional symptoms of brain injury
• Why loss of consciousness doesn’t determine concussion severity
• Repetitive and subconcussive impacts
• Sleep and circadian rhythm in brain recovery
• Why the old “cocooning” approach has changed
• Exercise, nutrition, and rehabilitation
• The importance of caregivers and community
• Identity changes after brain injury
• Emerging approaches to neurological recovery
• What we still don’t know about long-term brain health
