THE LONGEVITY LIE: Why One-Size-Fits-All medicine is failing and how precision can save your life

Most of what you have been told about living longer is a lie sold by the pound.Every year, millions of people spend billions on supplements, protocols and diets that promise to slow ageing. Most have never been tested in humans. Some have been tested and failed. A few are dangerous.THE LONGEVITY LIE dismantles the anti-ageing industry and follows the evidence to the only approach that holds up: precision medicine, care built around your biology instead of a marketing funnel.Written by a healthcare insider, not a guru. Chiaretto Calò is the CEO of a Swiss healthcare group that runs a medical centre and home-care services in Lugano. Son and brother of physicians, he spent a decade analysing medical innovation with the tools of finance: who funds a claim, who profits from it, and what survives when you read the trial instead of the press release. He has no supplement to sell you.Inside this book you will discover: - Why the Blue Zones may be a statistical artefact, and how a researcher won an Ig Nobel Prize showing that longevity hotspots track bad record-keeping, not good health.- Why the same drug that saves one life can kill another, and how a simple pharmacogenomic test tells you which category you are in before you swallow the first pill.- How the Number Needed to Treat exposes the dirty secret of blockbuster medicine: for many drugs you must treat more than a hundred people for one to benefit. The other ninety-nine get only the side effects.- How digital twins are turning medicine from guesswork into engineering, and how one patient avoided open-heart surgery when his virtual avatar showed what no standard test could.- Your first 90 days of precision longevity: concrete actions, red flags for fake personalisation, and a method to calculate your Biological Return on Investment.This book is for you if: - Your supplement shelf has grown faster than your confidence that any of it works.- You have been told your bloodwork is normal and you still do not feel well.- You want to understand healthspan, biological age and personalised medicine without a biology degree.- You are tired of longevity advice that changes with every new podcast.This is not a book against the desire to live longer. It is a book against longevity sold by the pound. No jargon and no protocol to buy at the end: 330 pages of evidence, sources and argument, so you can decide for yourself.If you have ever wondered whether your supplement shelf is buying you years or just expensive urine, start here.
