Thank you to Goodreads, the author and publisher for a copy of this book.

This is a very comprehensive and well-thought-out book with clear guidance and steps to be taken for longevity. It is very well researched, with references listed as well as a comprehensive health questionnaire in the appendix that the reader can use to better understand their own family health background.

There are a number of key areas of focus touched upon in the book and great deal of practical advice and recommendations, especially for someone approaching middle age. I’m essentially going to be keeping this on hand and using it as a step-by-step guide and implementing the recommended actions as time permits for getting on the path to improving my own health and longevity.

Your genes do not have to be your destiny!!! Florence Comite, MD has offered a wealth of information for good health. She does not give the usual blanket tips; but, instead, concentrates on the fact that it is MY unique biology that is the key to MY longevity. About half-way through this book, I ordered a continuous glucose monitor and wore it for two weeks. It was a real eye-opener, and I was shocked at the foods (and behaviors) that raised and/or lowered my glucose. As a result, I have taken some very precise proactive steps toward keeping my glucose balanced. I am neither diabetic nor pre-diabetic - just a 70-year-old who wants to understand my system and my genetics. It is, I believe, the most important investment I can make for myself and the people I love.

FYI: This book is heavy, detailed, and data driven. It is not a quick summary.

A Masterclass in Precision Medicine: Using Science to Rewrite Your Health Span
Dr. Florence Comite has spent her career at the leading edge of precision medicine, and Invincible: Defy Your Genetic Destiny is the definitive guide to her visionary approach. Rather than offering the generic wellness advice that saturates the market, Dr. Comite provides a sophisticated roadmap for understanding our unique biological blueprints.

One of the most refreshing aspects of this book is Dr. Comite’s courage in calling out the traditional healthcare system for what it truly is: a reactive model that often fails the patient. For anyone who has ever sat in a doctor's office feeling unheard—only to be told their "labs look normal" while they feel anything but—this book is a revelation. It is incredibly frustrating to be dismissed by the "standard of care," and Dr. Comite validates that experience while offering a superior alternative. She is truly brilliant, and she moves past the "average" ranges of standard medicine to help you decode your own biomarkers, from hormonal balance to metabolic health, with incredible precision.

The book’s greatest strength lies in its focus on actionable data. By demystifying the science of epigenetics, Dr. Comite proves that our genes are merely a starting point, not a pre-determined end. She provides clear, science-backed strategies for identifying "silent" health risks and pivoting your lifestyle to stay ahead of the aging curve.

Beyond the science, Dr. Comite is an amazing person for putting this knowledge into the world. It takes a truly dedicated and compassionate physician to challenge the status quo and provide people with the tools to reclaim their health autonomy. Her deep clinical insight and passion for longevity shine through on every page, making it clear that this book is a true reflection of a lifetime spent helping people thrive.

Invincible is essential reading for anyone ready to stop guessing about their health and start taking proactive, data-driven steps toward a longer, more vibrant life. It doesn't just teach you how to live longer; it teaches you how to stay "invincible" at every decade.

This disappointed me - but first, she tricked me into thinking she was sharing updated new information. So I bought the book. That's $25.00 I could have saved by using the library.

1) - I didn't like the author - she wasn't cutting edge. Falling back on old, sometimes debunked practices that have been updated on YouTube ... if you're a critical and well informed viewer.

2) - I don't think I can spend another 50 pages being lectured on how important sleep is. MY GOD! I've been an insomniac for 3 decades. Where's the breakthroughs for that epidemic. Just the tired old sleep heigene lectures. Darn it.

That said ... In Invincible, Comite provides a comprehensive action plan using her proprietary data to improve your health and longevity. By collecting the Five Key Biomarkers of Health, a snapshot of current and future health, and analyzing your family health history and lifestyle habits, you can recognize yourself in one (or more) of Seven Patterns of Health Decline. Once you know your patterns, Comite prescribes actions to reverse biological aging, metabolic disorders, heart disease and memory decline, so you can live in optimal health—strong, active, and happy—for the rest of your long life.

This book is incredible. Unlike most books on longevity written by influencers, Dr. Comite is a physician who pioneered this space decades ago and has loads of clinical research on what really works. What I appreciated most about the book was that it wasn't just written for people with endless money to spend or unrealistic lifestyles (going to be at 8 pm etc)

There are lots of small, medium and bigger takeaways that I felt could have a huge difference on my health immediately, depending on what I was ready for.

There was so much stuff I had never heard before-- like brushing your teeth three times a day helps ward off dementia!? Wild.

Highly recommended!

while this contains interesting tips and good ideas to implement in your every day life, i felt that the book spent way too much time explaining the problems instead of giving new solutions, and also trying to sell me things …
maybe it was because im already familiar with many of the terms and issues but i didn’t find the book as helpful as i thought it would (there are a few things that i look to implement though!)

Same advice you'd get almost anywhere except where the author advocates for using a continuous glucose monitor to check how your diet impacts your blood, and the encouragement to use GLP-1to help lose weight.

[Amy]

This was an interesting read that served to validate the healthy behaviors I've practiced for many years in the hopes of avoiding the fate that my genes may predispose me to as I age. I wish I had access to Florence's clinic and the funds necessary to be tested for personalized health strategies for my particular health concerns. Her over-promotion of continuous glucose monitoring was tiresome.

Every woman needs to read this book, no matter the age.

[Linda]

There are some good ideas in this book, continuous glucose moniter is one. Sleep is always good. I want to avoid drugs but doctors always push those.

[Maleah Grover-McKay]

Author is on an extreme end of a spectrum of manipulating hormones and using peptides. Anecdotal evidence to support.

[Jeff Keough]

Love the "five biomarkers of true health." Never once has my doctor given me those blood tests. An eye-opener to how backward healthcare is. Your health is in YOUR hands.

[Cathy Cole]

I have recommended this book more times than I can count. A easy-to-understand book about things that are not always easy to understand and an encouragement to be more proactive in my own health and wellness pursuits. There are definitely things I will incorporate and do based on reading this book as I seek to live as healthy a life as possible for as long as possible.
