Hi, I’m Lyndsey Simpson—Founder & CEO of 55/Redefined and author of The Age Rebellion. For years I’ve helped major organisations—from AXA and Amazon to Barclays and Diageo—turn longer lives and multigenerational workforces into a competitive advantage. My mantra is simple: if you don’t have an age strategy, you don’t have a growth strategy.

​

I’m also, unapologetically, a fixer. People come to me when they want to get things done. I’m direct, allergic to fluff, and far more plan‑and‑progress than crystals‑and‑mantras. Think “f**k your age—do it anyway” (with a wink) and a dose of humour. That’s the voice I bring to The Age Rebellion: practical, evidence‑based and packed with steps you can take now. I’ll share what most people never tell you about longer lives—and walk beside you as you become an Age Rebel.

​

Why this book, and why now? Because we’ve added decades to healthy life expectancy, yet we’re still being sold a story that says slow down, step aside and retire on autopilot. Every day I talk to people hungry for facts and purpose. My job is to arm you with clear knowledge and usable tools so you can design a life you’ll never want to retire from.

​

Beyond the page, I share this mission on stages and podcasts—on un‑retiring, the “rainbow of retirement,” and how multigenerational teams boost performance. And I have the privilege of leading 55/Redefined globally, where we’re age‑proofing the world’s largest organisations and helping millions feel inspired, not retired.

​

This isn’t a lecture; I’m not your mum or your boss—it’s a partnership. I’ll bring the data, the stories and a step‑by‑step framework. You bring your curiosity and the future you want to build. Together, we’ll rewrite what aging means—for you.

​

Want momentum as well as inspiration? I’m known for accountability with kindness—practical nudges, timely check‑ins and the occasional rallying cry when you need it. If that sounds useful, subscribe to my monthly email or follow along on socials for gentle prompts that keep your Age Rebel plan moving.
