It's not about years in your life. It's about life in your years.
Biological age can be measured — and it can be changed. Over eight years, the author of the book moved his from 47 to 25. This is how science approaches it.
Biological age — a complete guide to measuring and optimising it
Your calendar age is just a number. Your biological age determines how long — and how well — you will live. And it can be measured. It can also be changed.
GrimAge: what this epigenetic clock measures, how it is tested and what influences it
GrimAge is one of the best-known epigenetic clocks. We explain how it is calculated, how the blood test works, what the result really says about risk, and what research suggests you can influence.
Biological age — how to measure it and change it
Your calendar age is a number. Your biological age is reality. You can be 55 and function biologically like a 40-year-old — or the other way round. Today, science can measure both.
Autophagy — how the body cleans itself (and why most people block it)
Yoshinori Ohsumi received the Nobel Prize in 2016 for discovering autophagy. This cellular recycling mechanism is one of the most powerful anti-ageing tools there is — and it is free.
Blue Zones — what people who live to 100 really do
Sardinia, Okinawa, Ikaria, Loma Linda, Nicoya. Dan Buettner spent decades studying the communities with the highest share of centenarians. His conclusions surprised even the researchers themselves.
Movement isn't about calories — it's a biological signal
Movement is the cheapest and most effective biohacking intervention there is. Not because it burns calories — but because it reshapes your biology on dozens of levels at once.
Joints, collagen and the musculoskeletal system — an investment in mobility to 100
Most people only start paying attention to their joints once they begin to hurt. That is late — but not too late. Articular cartilage responds to load and nutrition. It is a dynamic system, not a static structure.
Longevity drugs: rapamycin, metformin, NAD+ and NMN
Rapamycin, metformin and NAD+ precursors are among the most closely watched molecules in ageing research. I take NMN myself and have had a good experience with longevity drugs. I explain how they work, what the studies showed and how to approach them sensibly.
Sarcopenia: why your muscles decide how you will age
The loss of muscle and strength with age is a silent process that stays invisible for years. We explain how to recognise sarcopenia by grip strength, how much protein and leucine you need, what creatine and strength training bring and why you should protect your muscles especially when losing weight.
VO2max: the strongest number in longevity — zone 2, intervals and strength
Cardiorespiratory fitness predicts lifespan better than most common risk factors. We explain how to build it with zone 2, Norwegian 4×4 intervals and strength training, how to measure it and how much exercise is enough even with a packed schedule.
