Muscle is one of the most powerful and most underestimated predictors of long-term health. Beyond appearance or athletic performance, skeletal muscle plays a direct role in metabolic function, insulin sensitivity, cardiovascular health, cognitive protection, and lifespan. This playlist covers the science of muscle mass and strength — how they decline with age, why that decline matters clinically, and the evidence-based strategies for building and preserving them throughout life. Topics include resistance training, VO2 max, zone 2 cardio, visceral fat, body composition, and the physiological relationship between physical fitness and longevity.

Morning habits quietly shape many of the biological systems that determine long-term health — from your metabolism and insulin sensitivity to your sleep quality, energy levels and cardiovascular risk. In this video I walk through the exact morning routine I use to support my metabolic health, stabilise blood sugar, improve focus and protect long-term longevity, explaining the science behind habits like circadian rhythm alignment, early light exposure, protein-rich breakfasts, post-meal walking and resistance training. After years working as an emergency medicine doctor, I’ve seen how many of the diseases that bring people into hospital begin decades earlier with small daily habits. The morning is one of the most powerful opportunities to influence your metabolism, brain function, and long-term health trajectory. In this video I explain the 10 evidence-based morning habits that consistently show up in longevity research — from sleep timing and circadian rhythm alignment to protein-focused breakfasts, post-meal walking, resistance training, and simple metrics like HRV and blood pressure that help you track your health over time. I’ll also show you the exact hour-by-hour framework I use on my days off between A&E shifts — including when I wake up, when I drink coffee, when I train, and why delaying caffeine and getting early light exposure can make a huge difference to energy, focus, and sleep later that night. None of this requires extreme biohacking or expensive supplements. These are simple, science-backed habits that compound over years and meaningfully reduce the risk of cardiovascular disease, diabetes, cognitive decline, and premature death.
