    Is AI Quietly Making Us Less Healthy? (022)

    We live in the most technologically advanced moment in medical history. We can track our sleep, monitor glucose in real time, sequence genes, and now consult AI at 2am about a symptom that’s bothering us. In this week’s After Hours, Steven and I asked a confronting question: is AI quietly making us less healthy? Not because it is malicious or unintelligent, but because of how we are using it. We’ve moved from “Dr Google” to conversational systems that sound calm, confident and personalised. That shift matters. AI collapses uncertainty into fluent answers. Medicine, however, is built on managing uncertainty carefully and over time. The human body heals through subtle signals, feedback loops and adaptation. Hormones fluctuate. Inflammation rises and resolves. Symptoms evolve gradually before they declare themselves clearly. A clinician watches patterns, context and change. An AI reads a snapshot of text. It cannot see your posture, hear hesitation in your voice, or weigh risk based on lived experience. Add to that the reality of data cut-offs, shifting guidelines and evolving safety warnings, and you can see the risk: beautifully written advice that may be incomplete, out of date or missing nuance. Confidence is not the same as correctness. That said, this is not an anti-AI argument. AI works exceptionally well in structured roles: summarising patient notes, spotting trends in glucose or sleep data, translating medical jargon into plain English, and supporting triage in overstretched systems. Used properly, it can improve health literacy and reduce administrative burden. My concern is when it begins replacing skill development or judgment. If AI reads every ECG or suggests every diagnosis, junior clinicians lose repetition, and repetition is how intuition is built. Technology should extend expertise, not erode its foundation. So here is the balance. Use AI to understand concepts, to generate better questions, to feel more prepared before you see your doctor. But do not outsource diagnosis, interpretation or decision-making to a machine that does not know you and is not accountable for you. AI is excellent at producing answers. Health, however, is about timing, context, restraint and relationship. Use the technology. Just don’t let it replace the thinking.

    Leadership, Stress and the Body: Why Your Environment Is Shaping Your Health (021)

    We rarely talk about leadership as a health issue, but we should. Most stress I see isn’t from workload. It’s from uncertainty, lack of control, and emotional unpredictability. The way we’re led at work, at home, and in our communities quietly rewires our nervous system. Over time, that shows up as poor sleep, gut issues, irritability and burnout. Leadership isn’t abstract. It’s a daily biological exposure. Leadership also isn’t about titles. It’s whoever people look to when things wobble. Whoever sets the emotional temperature of the room. Humans are wired to scan for safety, and supportive leadership restores predictability and agency. Controlling or erratic leadership keeps the body in low-grade fight or flight, where recovery never quite happens. We also talk about systems. Cities, workplaces and kitchens shape health more than motivation ever will. The same applies to ultra-processed food. These products are engineered for convenience and craving, not resilience. Avoiding them isn’t about being perfect. It’s about recognising patterns and being sceptical of foods that need marketing to look healthy. And finally, fatigue. Even with good sleep, regular exercise and “good numbers,” people can still feel wrecked. Sometimes tests help. Often the issue isn’t deficiency. It’s load exceeding recovery. Good metrics don’t always mean a rested nervous system. Health improves when leadership, systems and biology are aligned, not when we just push harder.

    The Taste Conundrum | After Hours (020) with Stephen

    A question came up on the podcast this week that sounds trivial, but really isn’t: Is something wrong with me if I don’t like a food everyone else loves? It came from my co-host, an Inner West Sydneysider surrounded by avocado on toast… who still can’t stand avocado. And the answer is no. Food preferences aren’t a character flaw. They’re biology, memory, culture, and expectation working together. What we call “taste” isn’t just the tongue. Flavour is a combination of taste, smell, texture, and what your brain expects to happen next. Avocado is a perfect example. For some people, it’s not the flavour, it’s the texture. Creamy but not smooth. Soft but not liquid. If your brain grew up associating avocado with sweet dishes and suddenly meets it in sushi or on toast, that mismatch alone can trigger dislike. That’s not fussiness. That’s neuroscience. Smell plays an even bigger role than most people realise. It’s why airline food tastes flat. Dry cabin air dulls your sense of smell, which means flavour collapses. It’s also why people add more salt, sugar, or fat when smell is reduced, and why spicy tomato juice or salty nuts suddenly make food more enjoyable in the air. When smell drops, the brain asks for intensity. This is where ultra-processed food becomes a problem. Artificial flavours give your brain the promise of nutrients without delivering them. Something tastes like banana, but there’s no banana nutrition behind it. The brain keeps searching, so you keep eating. Add high sugar, salt, fat, and soft textures that disappear quickly in the mouth, and appetite signals get confused. Pleasure becomes about intensity, not nourishment. The goal isn’t to force yourself to like everything. Some dislikes are genetic. Some tastes are acquired. Some just need better preparation. The real reset is understanding why you like what you like, eating real food most of the time, and listening to your body without shame. And if you still hate avocado after all that, that’s fine. You can be perfectly healthy without it… even if Inner West cafes disagree.

    What Ancient Health Advice Got Wrong About the Human Body | After Hours (019) with Stephen

    Many of the health sayings we still repeat today did not come from science. They emerged from humoral theory, early physiology guesses, cultural symbolism, and trial-and-error medicine that often mistook confidence for correctness. What survived wasn’t the mechanism or the evidence. It was the rhyme, the metaphor, the phrase that sounded right. Over time, these sayings detached from their origins, leaving behind advice that feels familiar but is often biologically meaningless or outright wrong. Practices like tobacco-smoke enemas, snake oil cures, bloodletting, and symbolic treatments such as “a hair of the dog” all share the same flaw: stimulation or short-term relief was confused with healing. Early medicine lacked an understanding of physiology, immunity, and inflammation, so visible reactions were taken as proof of effectiveness. Loud claims replaced evidence, persuasion replaced mechanism, and suffering was often moralised as part of treatment rather than questioned. Modern science paints a very different picture. Health outcomes depend on dose, mechanism, and reproducibility. Immune responses require energy, not starvation. Inflammation is a regulated biological process, not excess heat to be suppressed through deprivation. Nutrients only matter if they are absorbed, and symptom relief does not equal recovery. Even sayings that partially hold true, like “an apple a day,” do so not because of magic, but because they loosely align with broader dietary patterns that support gut and metabolic health. The pattern across centuries is remarkably consistent. Symptoms were treated as causes. Short-term effects were mistaken for solutions. Confidence was rewarded over accuracy. Science has not eliminated uncertainty, but it has replaced folklore with physiology and belief with mechanism. The sayings survived because they were memorable. The science moved on because it worked. And that, perhaps, is the most important health lesson we keep forgetting.

  5. Longevity: Perfection vs Consistency | After Hours (018)

    Longevity: Perfection vs Consistency | After Hours (018)

    As we step into 2026, it’s clear that better health isn’t going to come from another extreme plan, biohack, or viral trend. We already know more about health than any generation before us, yet chronic disease, burnout, anxiety and inflammation are still rising. That tells us the problem isn’t knowledge, it’s the systems, habits, and defaults we’ve accepted as “normal.” This episode of After Hours is about challenging those defaults and asking a harder question: what actually needs to change if we want to live longer, healthier, more resilient lives? The first shift is moving away from reactive health and towards daily maintenance. Most people only think about their health when something breaks, when blood results look bad, energy crashes or symptoms appear. But longevity isn’t built in crisis mode. It’s built through boring, consistent habits: regular movement, predictable sleep, hydration, real food and managing stress before it compounds. Prevention doesn’t feel urgent, which is why it’s so often ignored, but it’s the single biggest lever we have. We also need to rethink our relationship with food, not just what we eat, but how it’s produced and marketed. Ultra-processed foods have quietly become the foundation of modern diets, designed for shelf life and profit, not human biology. Inflammation, metabolic dysfunction, and gut issues aren’t personal failures, they’re predictable outcomes of an environment stacked against us. Choosing more whole foods, fewer ingredients, and slowing down how we eat isn’t about perfection, it’s about reducing the constant biological stress we place on the body. Finally, longevity isn’t just physical, it’s social and psychological. Isolation, chronic stress, poor sleep, and lack of purpose age us just as fast as poor nutrition. Strong routines, meaningful relationships, time outdoors, and a sense of contribution matter more than most supplements ever will. If 2026 is going to be different, it won’t be because we tried harder. It will be because we made better choices easier, stopped outsourcing responsibility for our health, and committed to small changes we can actually sustain.

    New Year, Without the Extremes | After Hours (017)

    In this After Hours episode, Marty and I talk about something I care deeply about this time of year: how to start the New Year without burning out by February. We unpack why consistency always beats extremes, how the “new beginning” effect can work for or against us, and why your environment and season matter more than motivation. An Australian summer makes movement easier. A Northern Hemisphere winter demands planning. Neither needs perfection. We walk through the real foundations of health: hydration, daily movement, food quality, stress resilience, and sleep. Not as biohacks, but as simple habits that compound. We talk walking (6,000–10,000 steps), an 80/20 approach to food, why ultra-processed foods are engineered to keep you craving more, and how small planning decisions can quietly protect your health. Sleep gets the spotlight it deserves. It’s the pillar that makes everything else work:repair, metabolism, cognition, and emotional regulation. Phones, blue light, and constant stimulation are working against biology that hasn’t changed in thousands of years. We also touch on apples, antioxidants, gut health, and the importance of building routines that your nervous system can actually sustain. Health isn’t about doing everything. It’s about doing a few things well, every day. If you’re looking for a calmer, smarter reset to 2026, this episode is for you. This is After Hours. Honest. Human. And real.
