What if the biggest mistake we’ve been making about midlife is believing it’s the beginning of the end?
In a powerful conversation with The Midlife Mentors, Lyndsey Simpson challenged many of the outdated assumptions society still holds about ageing, work, retirement, purpose, and reinvention.
As the founder and CEO of 55/Redefined, Lyndsey works with over 300 organisations globally helping businesses become more age-inclusive and future-ready. Her new book, The Age Rebellion, explores what happens when people stop sleepwalking through midlife and start consciously redesigning the next chapter of their lives.
And according to Lyndsey, that chapter could be the most exciting one yet.
“The Biggest Regret Was Retiring”
Lyndsey explained that her journey into the world of midlife reinvention started unexpectedly while running a recruitment and HR outsourcing company.
A major bank approached her needing experienced bankers from the 1990s to help with a regulatory review. The challenge? Most of those professionals had already retired.
Using nothing more than an old mobile phone contact list, Lyndsey began calling former colleagues and asking if they would consider returning to work.
Within eight weeks, she had hired 400 people out of retirement.
But it wasn’t simply the scale of the response that surprised her.
It was what those people said.
“The biggest regret almost all of them shared was retiring,” she explained.
Many had spent decades chasing retirement as the ultimate goal, only to discover they had never truly thought about what would replace the structure, purpose, identity, and connection work had provided.
“They’d done the holidays, finished the to-do lists, renovated the house, started the hobbies,” she said. “Then suddenly they realised they still had decades of life left — and no real plan for how they wanted to live it.”
Why Midlife Feels So Uncomfortable for So Many People
One of the strongest themes in the discussion was the emotional and psychological disruption that often comes during midlife.
According to Lyndsey, the years around 50 to 55 often become a major “pivot point” where multiple life transitions collide at once.
Careers stagnate.
Relationships change.
Children leave home.
Hormones shift.
Questions around identity become louder.
For many people, it’s the first time they stop and ask:
Is this really the life I want?
Claire reflected on how many people arrive at midlife after years of following a script they thought would bring happiness — career success, stability, financial security — only to discover something still feels missing.
Lyndsey agreed.
“So many people know exactly what they don’t want anymore,” she said. “But they have no idea what they do want.”
And that uncertainty often leads people to stay stuck.
They continue repeating routines that no longer fulfil them because the unknown feels frightening.
The Fear That Keeps People Trapped
A major part of the conversation focused on fear — particularly fear of change and fear of disappointing others.
Lyndsey spoke openly about how many people remain trapped in careers, relationships, or lifestyles that no longer fit simply because they are afraid of what might happen if they changed direction.
Some fear financial instability.
Others fear judgment.
Many fear losing their identity altogether.
She gave examples of people feeling unable to admit they no longer want the life they once worked towards:
- The professional who secretly hates their job but feels responsible for supporting their family
- The grandparent who loves their career and doesn’t want full-time childcare responsibilities
- The person terrified of retraining later in life because they fear failure
“The stories we tell ourselves become the cage,” James reflected during the discussion.
And often those stories are inherited from outdated societal beliefs about ageing and success.
Reinvention Is Not a Luxury — It’s a Necessity
One of the most inspiring moments came when Lyndsey shared the story of her brother.
After more than 30 years working in supermarkets, he reached a point where he knew he could not continue doing the same work indefinitely. But like many people in midlife, he felt trapped by financial responsibility and uncertainty.
Using the Japanese concept of Ikigai — the idea of finding the intersection between what you love, what you’re good at, what the world needs, and what you can be paid for — Lyndsey helped him rethink his future.
He eventually retrained as an audiologist, completed a university degree in his late 40s, bought multiple businesses, and discovered a renewed sense of energy and purpose.
For Lyndsey, stories like this prove something important:
“You are allowed to become someone new.”
In a world where people may live to 100, reinvention is no longer unusual — it’s essential.
Why Retirement No Longer Makes Sense
Throughout the conversation, Lyndsey repeatedly challenged the traditional idea of retirement.
She argued that many people still think about work in outdated, binary terms:
Working or retired.
But modern life no longer fits that model.
Instead of a cliff-edge retirement, she believes people should think in terms of gradual transitions, portfolio careers, purposeful projects, learning, mentoring, consulting, volunteering, entrepreneurship, and meaningful contribution.
“We need to stop asking, ‘When do I retire?’” she said.
“And start asking, ‘How do I create a life I never want to retire from?’”
That doesn’t necessarily mean working relentlessly forever.
It means staying engaged, curious, mentally stimulated, connected, and purposeful.
Research increasingly supports this idea. Meaningful work, contribution, and social engagement are strongly linked to mental wellbeing, cognitive health, and longevity.
Midlife Men, Hormones & the “Midlife Crisis” Myth
The discussion also explored an area still rarely talked about openly: male hormonal health and andropause.
While menopause conversations have become far more visible in recent years, many men still struggle silently through hormonal shifts, low testosterone, declining confidence, anxiety, fatigue, and emotional withdrawal.
Lyndsey praised the growing conversation around menopause but pointed out that men are often simply labelled as having a “midlife crisis” without being offered meaningful support or education.
James highlighted how many men in midlife experience a profound identity crisis tied not just to hormones, but to purpose, career pressure, ageing, and emotional suppression.
It’s one of the reasons midlife coaching, psychology, wellbeing education, and corporate wellness support are becoming increasingly important.
Why Community Matters More Than Ever
Another powerful idea explored in the discussion was the importance of community and what Claire described as “borrowed belief.”
Sometimes, before we believe in ourselves, we need to spend time around people who already believe change is possible.
Lyndsey spoke passionately about surrounding yourself with people who inspire growth rather than reinforce limitation.
Because midlife is often shaped by the narratives we absorb from those around us.
If everyone in your circle believes ageing means decline, invisibility, and limitation, it becomes difficult to imagine a different future.
But if you see people reinventing themselves, starting businesses, studying, travelling, creating, and thriving later in life, possibility expands.
“Book an Appointment With Yourself”
Toward the end of the discussion, Lyndsey shared the one thing she believes everyone in midlife should do.
“Book an appointment with yourself,” she said.
Not five distracted minutes between emails.
Actual time.
Time to ask:
- What do I want the next decade of my life to look like?
- What energises me now?
- What no longer fits?
- What kind of relationships, health, work, and lifestyle do I truly want?
- What would reinvention look like for me?
Because the biggest danger, she believes, is not failure.
It’s sleepwalking through the next 20 years without intention.
Midlife Is Not “All Downhill”
As the conversation closed, one message became incredibly clear:
The old narrative around ageing is outdated.
Midlife is not a decline.
It is not irrelevance.
It is not too late.
It can be a period of reinvention, purpose, confidence, creativity, leadership, wisdom, and freedom — if we are willing to challenge the old rules and consciously redesign what comes next.
And perhaps that’s the real rebellion.
Not fighting ageing.
But redefining what ageing can actually look like.
If you’re navigating change in midlife — whether around career, purpose, relationships, wellbeing, leadership, identity, or mental health — we’d love to support you.
