Your brain has its own immune system, and whether those immune cells protect your brain or attack it depends largely on your metabolic health, which you control with what you eat, how you move, how you sleep, and even the air you breathe. Dr. David Perlmutter is a board-certified neurologist and six-time New York Times bestselling author of Grain Brain, Brain Maker, Drop Acid, and now Brain Defenders. He explains how microglia, the brain's immune cells, shift from brain defenders to brain destroyers when your metabolism breaks down, and why that shift sits underneath Alzheimer's, Parkinson's, multiple sclerosis, and even depression. The conversation covers the diet pillars that keep blood sugar in check, why you need both cardio and strength training, how poor air quality and poor sleep feed inflammation, and the tests that show where you stand long before your memory slips. He closes with his three strategies for wellness: have fun, stay socially connected, and take charge of your own health destiny.

The way to recover stronger from surgery is to build the foundation before you ever get to the operating room: go in with as much muscle as you can keep, feed the repair with protein, and get your sleep, stress, and inflammation under control, then layer on advanced tools only with a doctor's guidance. Zora Benhamou is a gerontologist, healthy aging coach, and host of the Hack My Age podcast. After years of fighting osteoarthritis with injections, diet, and rehab, she had both hips replaced 12 weeks apart. She walks through how she kept her muscle with blood flow restriction bands, what she ate to rebuild bone around the implant, which peptides and other biohacks she tried, and why none of them matter without the basics. She closes with her three strategies for aging well: nurture your network, learn to breathe through your nose, and understand your hormones.

Better sleep after 40 comes from building the right daily rhythms, not from trying harder at bedtime. Mollie McGlocklin, creator of Sleep Is a Skill, makes the case that sleep is a learnable skill, and that forcing it or chasing a perfect score on your tracker usually makes it worse. Mollie went through acute insomnia while traveling overseas and left doctor after doctor with sleeping pills and no real guidance. In this episode she explains what sleep latency and sleep efficiency tell you, why falling asleep the second your head hits the pillow can be a red flag, which tracker numbers you can trust (and why deep sleep and REM aren't among them), when a nap helps and when it hurts, what to do when good sleep habits aren't enough, and why sleep really begins in the morning. Time Stamps: 03:42 Why you can't force sleep 05:07 Mollie's insomnia story 06:17 Sleeping pills and the case for CBT-I 09:07 Sleep as a skill, not a sleeper type 11:36 Sleep latency: when falling asleep fast is a red flag 13:18 Sleep efficiency and nighttime wakeups 14:51 Binaural beats, white noise, and sleep sounds 17:28 Sleep stages and why tracker data misleads 18:37 Blood oxygen averages and missed sleep apnea 20:12 Track trends in one device: HRV and heart rate 23:35 How wearables spotted COVID early 25:14 Why sleep apnea testing should be repeated 27:18 Naps and the insomnia exception 28:49 The caffeine nap 31:50 Shift workers and longer naps 33:37 When sleep hygiene isn't enough 35:15 CBT-I, ACT, and circadian entrainment 38:52 The health of your word 39:09 Sleep begins in the morning 40:48 Loneliness, relationships, and sleep 41:29 What hunter-gatherers teach us about sleep Links: Sleep Is a Skill (newsletter, podcast, and coaching): https://sleepisaskill.com The Wellness Roadmap: https://amzn.to/3U1xEdn

Pain is built by the brain, and because the brain can change, pain can change. That is the core of what pain psychologist Dr. Rachel Zoffness lays out in this episode. Pain is never all in your head, but it is never only in the body part that hurts either. It is biopsychosocial: biology, psychology, and your social world all turn the volume up or down. Dr. Zoffness is faculty at the UCSF School of Medicine, lectures on pain science at Stanford, and is the author of Tell Me Where It Hurts: The New Science of Pain and How to Heal. She walks through her three core truths about pain, why 96% of medical schools teach no dedicated pain science, the pain dial (how stress, mood, and attention change what you feel), and the pain recipe: writing down what makes a bad pain day so you can build the opposite. She closes with the three things that matter most for a healthy life with pain: movement, social health, and balance. Time Stamps: 03:48 Why pain is coming for all of us 07:56 Core truths 1 and 2: pain is the brain's opinion, and the brain can change 10:40 Core truth 3: pain is always biopsychosocial 16:05 A hammer and a bigger hammer: why medicine reaches for pills and surgery 19:41 The sociological domain: loneliness, trauma, and the 80% overlap 23:06 Acute vs. chronic pain, and the opioid lie 26:40 The pain dial: how stress and anxiety turn the volume up 27:46 Mood and attention change pain volume 32:03 Your high pain recipe, your low pain recipe, and painsomnia 36:11 Movement first, pain reduction later 37:35 Loneliness, cortisol, and social health 41:12 You have more power over your pain than you've been told Links: Dr. Rachel Zoffness (free resources page): https://www.zoffness.com Tell Me Where It Hurts: The New Science of Pain and How to Heal Instagram: @therealdoczoff Fit for Task Muscle and Strength Workshop: https://40plusfitness.com/muscle

You can still build muscle after 40, and the research says you can build it at close to the same rate as a 25-year-old. What has to change is not how hard you train, it is how strategically you train, eat, and recover. Alain Gonzalez is a fitness coach, author, and the creator of the largest YouTube channel dedicated to men's fitness over 40. He has spent more than 17 years helping men build muscle and get their health back, and his book is Muscle After 40. In this conversation we walk through his four pillars of muscle growth: mindset, training, nutrition, and recovery. We cover why volume is the thing that has to change with age, why movement quality sits above everything else in the gym, how to order your nutrition so protein comes first, and why recovery is the pillar most people over 40 quietly skip.
