The Third Act Revolution: Ageing on Your Own Terms

Thriving in your 40s and beyond, without shrinking, apologising, or pretending

Everything you’ve been told about midlife is a lie. It’s not a slow decline. It’s your strategic advantage. If you know how to claim it.

If you’re a woman over 40, you already know the script society has written for us:

• You’re supposed to fade quietly.

• You’re supposed to accept fatigue and feeling “off” as just part of the deal.

• You’re supposed to shrink. Physically, mentally, socially.

Well. I’m not buying it.

Midlife isn’t about decline. It’s about design.

Not by pretending we’re 30, chasing youth, or buying into the outdated notion that a woman’s value peaks before 50. Instead, we rewrite the rules. We take back agency over our health, our minds, and the way we show up in the world.

Because decline is optional.

Why I Started Shenmag

I know what happens when health takes a backseat.

I lost both my parents to smoking-related illnesses. I was my father’s caregiver in his final months, watching the slow, painful consequences of years of poor lifestyle choices. That experience changed everything.

It made me rethink how I wanted to live the rest of my life.

I decided to make ageing a power move, not a passive process.

That’s why I quit my corporate career, immersed myself in neuroscience and brain health, and became a certified Brain Health & Life Coach. I trained at the Académie Européenne des Neurosciences, The Brain Academy, Amen University, and Mindvalley — not just to transform my own future, but to help other women do the same.

Now I’m building Shenmag, a space for real, science-backed insights into brain health, ageing, and reinvention. Without fear-mongering or anti-ageing gimmicks.

Facing the Challenges

Starting over wasn’t easy. Leaving behind a secure career to step into a world that still sidelines midlife women? Daunting.

I also see how the wellness industry either infantilises women or sells them expensive “fixes” for problems that were never there in the first place.

The biggest challenge? Cutting through the noise.

Finding a way to talk about ageing that feels empowering, strategic, and honest. A way that isn’t about turning back the clock, but about future-proofing your brain, body, and mindset for the long game.

Designing My Own Third Act

I don’t see midlife as a period of loss but as the exact opposite, a period of gain!

I trained in brain health, lifestyle transformation, and emotional resilience. Not just to help myself, but to build a roadmap for other women navigating this space.

That’s what Shenmag is about:

• How to stress-proof your brain and stay mentally sharp.

• How to build a vibrant future without waiting for permission.

• How to age intentionally.

Expect science-backed insights, no-nonsense strategies, and the occasional philosophical deep dive.

Think Stoicism meets neuroscience meets an unfiltered conversation with your rebellious friend.

Who I Help

I work with smart, accomplished women who refuse to let outdated narratives dictate their Third Act. Women who are ready to shape the next decades with clarity, confidence, and a touch of rebellion.

Most women aren’t looking for a miracle cure or another anti-ageing gimmick:

• They want clarity.

• They want a strategy.

• They want to feel sharp, strong, and in control.

That’s where I come in.

How I Help

As a Brain Health Strategist, I help women future-proof their minds, bodies, and lifestyles, without fear-mongering or unrealistic wellness trends.

Through a science-backed, strategic approach, I guide my clients to:

• Reclaim cognitive strength — Whether it’s forgetfulness, or decision fatigue, I help women sharpen their thinking, improve memory, and build mental resilience.

• Navigate perimenopause & hormonal shifts with confidence — I bridge the gap between brain health and midlife biology, showing women how to work with their changing bodies, not against or despite them.

• Design a lifestyle that enhances longevity and vitality — From stress-proofing the nervous system to creating habits that support sustained energy, motivation, and mental sharpness, I make ageing a power move, not a passive process.

• Rethink midlife as an opportunity, not a decline — I challenge outdated narratives and help women build a future where they set the rules, reclaim their visibility, and shape their next decades with purpose.

Midlife isn’t about shrinking. It’s about expanding into your full potential. If you’re ready to stop waiting and start designing your future, I can show you how.

What’s Next

Midlife isn’t for sale. If you’re done with the anti-ageing gimmicks, and the outdated scripts — this is your space.

💡 Women over 50 control 80% of household wealth, yet we’re still treated as an afterthought in media, culture, and business.

💡 The wellness industry profits from keeping us insecure and, of course, if we believed we were in our prime, how many anti-ageing products would suddenly seem useless?

💡 The traditional ageing narrative tells us to either disappear or desperately cling to youth. Where’s the model for bold, intelligent, thriving midlife women?

Right here.

I publish three times a week, delivering sharp insights, bold challenges, and real strategies for women who refuse to fade.

Testimonials

Stéphanie has given me clear and easy steps to follow, and I started seeing improvements almost immediately. After four sessions, I felt less scattered and anxious and had even lost nearly five pounds without even really trying. Her thoughtful advice and genuine ability to listen have made such a difference.

— Muriel B.

Since starting the coaching, I’ve noticed big changes in my attitude, diet, and exercise. My gut health is a lot better, and I’m starting to lose a bit of weight. Stephanie really listened to what I needed and helped me see how being out of balance was affecting me. Her support gave me the confidence to use my own strength and start moving toward feeling healthy and whole again.
