Two adults. Same chronological age. Fifteen years apart in how they look, move, and think. The reason has almost nothing to do with genes.
The anti-ageing industry sells $80 billion of supplements, creams, and protocols every year. The data on whether any of them actually slow biological ageing is, almost without exception, weak.
What actually slows ageing is unglamorous. It is not a peptide stack, a fasting-mimicking diet, or a cold plunge. It is a small set of habits - five of them - that compound across decades. The people who do them age dramatically slower than the people who do not. The gap is visible by 50, undeniable by 60, and it is the difference between a sharp 80-year-old and a fading one.
This is the guide to those five habits.
Age Slower is the foundation book of the Hybrid Force Limitless series - written in plain English, grounded in actual evidence, and structured for adults with day jobs and zero patience for biohacker theatre.
Inside the book:
- Why biological age and chronological age can differ by fifteen years in either direction - and which inputs move the gap
- The five habits with the strongest evidence for slowing ageing across every body system (the answers are unglamorous and free)
- Why muscle mass is the single strongest predictor of healthspan after forty
- The sleep architecture that protects the brain, the metabolism, and the skin
- The protein intake target that prevents the silent muscle loss most adults don't notice until they can't get up from the floor
- Why loneliness is biologically as damaging as fifteen cigarettes a day - and what to do about it before it shortens your life
- The exercise types that actually slow biological ageing (it is not running)
- The habits that accelerate ageing - and why most adults are doing several without realising
- Why most anti-ageing supplements fail clinical trials, and which interventions have actual evidence behind them
This is the first book of a fifteen-title series covering chest fat, heart health, sleep, vegetarian protein, hybrid training, time-restricted eating, environmental toxins, barefoot health, strength, rucking, and more. Each book solves one specific problem. Twelve-week programme companions turn the philosophy into a calendar.
