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 one of the most powerful things we can do for our health is simply less.
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.
Key Factors That Truly Impact Aging After 40
I’m a bioscientist studying aging. 🧬 If you’re 40+, this is what actually matters ↓
Six Key Habits to Safeguard Your Brain After 40
I’m a bioscientist studying aging & dementia prevention 🧬 If you’re 40+, these 6 habits matter most for protecting your brain 🧠↓
Racket Sports Slash Mortality, Boost Heart and Brain Health
Racket sports are linked with some of the largest reductions in all-cause mortality among common physical activities. The mix of short intense bursts, brief recovery, balance, coordination, and fast reactions is great for heart and brain health. Take this as...
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.
Eat 30 Plant Varieties Weekly for Microbiome Health
As a scientist studying aging, I’m fully behind the “eat 30 different plant foods per week” advice. The research linking microbiome diversity to long-term health is compelling. Fruit, veg, legumes, herbs, nuts, and seeds all count — it’s more achievable than...
Prioritize Healthspan over Chasing Immortality
As a longevity scientist, I’m not interested in helping people live forever. I’m interested in helping people avoid the long period of decline and chronic disease that has become normal in the final 10–20 years of life. Extend healthspan - and a...
Your 40s‑50s: Crucial Years for Lifelong Health
As a longevity researcher, I can’t stress this enough: Your 40s and 50s are one of the most influential periods for shaping long-term health and age-related disease risk. The key is simply finding your version of the basics you can sustain -...
15 Bioscientist Habits to Tame Silent Inflammation
Chronic inflammation is silent — but it’s a key driver of many age-related diseases. 🧬 Here are 15 habits I prioritise as a bioscientist to keep it in check ↓
Longevity Comes From Simple Daily Habits, Not Extremes
I hate to break it to you, but the world’s longest-living people aren’t doing anything extreme. They move daily, eat mostly whole foods, sleep consistently, and have strong social connections. Boring. Effective. Evidence-based.
Consistency Over Perfection: 80% Is Enough
As a health scientist, I’m giving you permission to stop optimising. “Good enough” is where most of the benefits come from. Get your sleep, diet, and movement routines right 80% of the time. That foundation alone puts you ahead of most people. Consistency beats...
Simple Daily Habits Yield Big Long-Term Health Gains
Simple habits, big return for long-term health: → Morning sunlight (10 mins) → 10-minute walks after meals → Lift twice a week → Consistent sleep timing → 7,000 steps daily Accessible. Evidence-based. Effective.
Basic Sleep, Exercise, Nutrition Trump Extreme Longevity Hacks
After almost a decade studying the biology of aging, I hate to break it to you: Consistency with the basics — sleep, movement, and nutrition — outperforms most extreme protocols when it comes to longevity.
Four Essential Weekly Movements for Longevity
As a bioscientist studying aging, these are 4 types of movement I try to include each week: 👉 Walking 👉 Strength training 👉 Higher-intensity cardio 👉 Mobility work
