Dr jemma King, sleep researcher and author of *Sleep Smarter, Think Sharper, Feel Better*, breaks down the science of what actually happens when you close your eyes: from the human growth hormone spike that only hits in your first two sleep cycles, to why your late-night coffee is still in your bloodstream at 2 AM. This is one of those conversations that will change how you think about every single night. Practical, science-backed, and no fluff. See omnystudio.com/listener for privacy information.

Most Australians know alcohol isn't great for them — but almost nobody knows it directly causes 7 types of cancer, or that just 3 standard drinks a week raises breast cancer risk by 15%. Dr Chris Davis is a GP and addiction specialist who built a telehealth program to make alcohol treatment actually accessible — no waiting lists, no rehab wards, no judgment. In this episode we get into the chemistry of what alcohol actually does to your body, why your sleep is being quietly destroyed, and what the data says about who's really drinking at risky levels in this country. If you drink — or love someone who does — this one's worth your time.

In this episode, he walks through the full hormone production pathway from the hypothalamus to the testes, explains which blood markers most GPs overlook, and outlines the lifestyle, nutrition, and supplementation strategies he has used to bring his own testosterone to near-1,000 nanograms per deciliter naturally. The conversation also covers structural causes of low testosterone, the role of HBOT and sleep in hormone health, and when TRT becomes the appropriate next step.

Most people think longevity is about diet and supplements. Alexis Fernandez, cognitive neuroscientist, says the real killers are chronic stress, isolation, and outsourcing your brain to your phone. In this episode of Project 100, Mark Bouris sits down with Alexis to unpack what the science on centenarians actually shows — and it's simpler, and more confronting, than most people want to hear. From cortisol dysregulation to synaptic pruning to why resistance training is the best thing you can do for your brain, this conversation will change how you think about what it means to age well.
