Community Connection Is Essential Medicine for Longevity
Something I’ve realised over the past few years: You can do everything “right” with diet and exercise, but if you’re lacking connection, something feels missing. Feeling part of a community not only makes everyday life feel better, but the biological effects on health and longevity are also now well established. Connection is biological medicine.

Three Key Nutrients for Brain Longevity, Plus Polyphenols
As a bioscientist studying aging, my top 3 nutrients for brain longevity are: → Omega-3s (fatty fish 2–3x/week) → Vitamin B12 (beef, dairy) → Choline (2 eggs daily) Plus plenty of polyphenol-rich foods: berries, extra virgin olive oil, cocoa, nuts, and coffee.
Health Is the Only Thing That Truly Matters
Everything feels important - until you get sick. Then you realise there was only ever one thing that truly mattered: Your health. As a bioscientist, I’ve dedicated my career to understanding how we protect it before it’s lost.
Small Daily Habits Compound Into Lifelong Longevity
As a scientist studying aging, I can’t stress this enough: You don’t need to optimise everything. What really moves the needle is the compounding effect of small habits repeated over years. The 20-minute daily walks. The nutrient-dense, fibre-rich breakfast bowl...
Basics Beat Gadgets: Sleep, Food, Relationships, Movement

As a bioscientist studying aging, I could list 50+ reasons why adults 40–60 should be resistance training. Here are 3: 1) Muscle is a major site of glucose disposal - improves blood sugar regulation 2) Key to maintaining physical function and independence...
20 Minutes of Daily Stillness Boosts Longevity
As a longevity scientist, I’m giving you permission to do absolutely nothing for 20 minutes a day. No phone. No guided meditation. Just sit and let your mind wander. We’re more overstimulated than we realise, and it may be that...
Supplements Fail Without Solid Sleep, Diet, Exercise Foundations
Controversial opinion: the supplement industry is largely built on people’s reluctance to do the unglamorous basics. For most people, supplements have limited impact if sleep, diet, exercise, and lifestyle foundations aren’t nailed down. Sort the foundations first.
