We have added 30 healthy years to life expectancy in the last century alone. Whether you're approaching retirement, navigating a career change, or simply wondering how to live a meaningful life in your later years, it's not just about planning—it’s about creating a life that defies expectations and maximizes the incredible potential of your most experienced years. The Age Rebellion, by age-diversity entrepreneur and pioneer Lyndsey Simpson, offers an inspiring, action-oriented approach to breaking free from outdated tropes about growing older. This book empowers readers to reclaim control and revise the rules of what’s possible, with alternatives to traditional retirement that allow them to redesign their future, their way. A life of continued growth, productivity, and impact is possible—no matter your age.
 

  • "The Age Rebellion is a roadmap for the New Longevity era. As we all live longer lives, how do we design a life that will have meaning and purpose? In this must read, Simpson reports on how individuals, businesses and society can create a new template for today and future generations that may live to 100!"
    Michael Clinton, founder & CEO of ROAR forward and author of ROAR and Longevity Nation
  • “At 50, I feel more energized, more curious, and more driven by purpose than at any other time—and The Age Rebellion explains exactly why. Ikigai has taught me that meaning deepens with age, and this book gives us the roadmap to design a future that matches that truth. It tears up the old rulebook on ‘retirement’ and helps you plan for the extra 30 years modern life now offers. A brilliant guide for anyone ready to rewrite what comes next.”
    Sam Smith, founder of finnCap/Cavendish Financial and author of The Secret Sauce
  • "We've won the longevity lottery-yet we're still living by a life script written for much shorter lives. The Age Rebellion is a sharp, unsentimental wake-up call for anyone who suspects the problem isn't aging, but outdated assumptions about it. With clarity, evidence, and just the right edge, this book exposes how early we sideline experience, ambition, and relevance-and why that's a colossal waste of human potential. This isn't about aging gracefully or embracing retirement chic. It's about rewriting the rules for work, identity, and purpose across a 100-year life. Smart, timely, and quietly radical."
    Avivah-Wittenberg-Cox, CEO, 20-first and host of the 4-Quarter Lives podcast
  • “Few things are as important now as how you age and what to do with those extra years that longer lives bring. This book will make you think hard about what you want to do and how to do it. Whatever your age you have more years ahead of you than past generations and need to age differently. It‘s time to join the age rebellion.”
    Professor Andrew J. Scott, author of The Longevity Imperative and The 100-Year Life
  • “As Shakespeare might have said, ‘To retire or not to retire, that is the question!’ Lyndsey Simpson’s book is the perfect primer for answering that question—and more importantly what to do about it! At age 91, it even gave me some new ideas!”
    Alan Patricof, cofounder and chairman, Primetime Partners
  • “Retirement bad! Living good! Refreshingly salty, unapologetically un-woo-woo, and totally inspirational.”
    Ben Miller, actor, comedian, and bestselling author of It’s Not Rocket Science
