When the concept of retirement was invented, it was designed for a very specific set of circumstances: a man who had worked in physically demanding labour for 40 years, whose body was worn out by his mid-60s, and who — statistically — had perhaps five to ten years left to live. A pension that covered those final years was, in that context, a generous and sufficient provision.
That world no longer exists. But the financial planning that was built for it largely does.
Lynda Gratton and Andrew Scott's book The 100 Year Life made me confront a mathematical reality I had been quietly avoiding: if I live to 90, I have 26 more years to fund. If I live to 100 — which is increasingly plausible for men who are physically active and not seriously ill — I have 36 more years. The planning required for 36 years of post-work life is categorically different from the planning required for 10.
The three-stage life — education, work, retirement — was designed for a 70-year lifespan. For a 100-year life, it is not just inadequate. It is a slow financial disaster.
The Maths That Should Change Your Planning
Let me make this concrete. A man who retires at 65 with savings of R3 million (a figure that sounds substantial) and who lives to 95 needs that money to last 30 years. With conservative investment returns and inflation, that R3 million provides roughly R100,000 per year in today's money. That is less than R8,500 per month.
For most men who have maintained a reasonable lifestyle in their working years, R8,500 per month is not an adequate income for 30 years of active, engaged living. It does not fund travel. It does not fund legacy gifts to children and grandchildren. It certainly does not absorb a health crisis.
Gratton and Scott's argument is not that you need to save more — though that helps. It is that you need to fundamentally restructure your assumptions about how many stages your life has and how long each stage lasts. The three-stage model (education → work → retirement) made sense when each stage lasted roughly two decades. When the final stage potentially lasts four decades, the model breaks.
The Multi-Stage Life — And What It Means Practically
Gratton and Scott propose that a 100-year life is better understood as a multi-stage life — one that might include two or three distinct career phases, periods of intentional reinvention, and a much more gradual transition into lower-intensity work rather than a hard stop at 65.
For me, this has translated into a specific plan: re-design my lifestyle so that I can live long and strong to the age of 100 — working from anywhere, at any time, until the day I die. Not a staircase of retirement dates. A different shape of working life altogether.
In practice, that means three things:
- Work that travels. Income that isn't tied to one office, one country or one employer. If the work can be done from a laptop in Kerry, it can be done from a laptop anywhere — and that removes the single biggest reason men are forced to stop earning.
- Work that scales down, not off. Instead of a hard stop, the intensity varies while the earning continues. Some years full tilt, some years a few hours a week — chosen, not imposed.
- Work that outlasts my energy. Writing, teaching, coaching, building a community. The website you are reading is the beginning of this. These are activities I can still do at 85 if I have looked after my mind and my health — which is precisely why the health plan and the financial plan are the same plan.
The financial implication of this is significant. Every year I keep earning beyond 65 is a year I am not drawing down savings — and a year I am adding to them. The compound effect of extending your earning period by ten or twenty years is far more powerful than saving an extra percentage point in your 40s.
The Core Reframe
Stop thinking about retirement as a date you are working toward. Start thinking about it as a gradual transition across two decades. The financial pressure this removes — and the identity continuity it provides — are both transformative.
The Three Levers That Actually Matter
Rather than getting lost in the complexity of financial products and investment strategies, Gratton and Scott identify three levers that have the most impact on financial longevity:
1. Extend your earning period
As I've described above, this is the single most powerful lever. Every additional year of income reduces the savings burden and allows compounding to continue working for you rather than against you.
2. Build productive assets
Gratton and Scott distinguish between "productive assets" — skills, knowledge, networks, and businesses — and "transformational assets" — experiences and relationships that give life meaning. Both matter. But productive assets generate income; they are not depleted by use. A skill you develop at 60 can still be earning for you at 80. A rental property bought at 55 can be providing income at 90. These are different from a pension pot, which can only be drawn down.
3. Reduce fixed costs
The most practical financial move many men in their 60s can make is reducing their fixed monthly obligations. Paying off the home loan removes the single largest fixed cost most families carry, creating enormous flexibility for everything that comes after.
What I Am Doing — And What You Can Start Now
My own financial plan is built around these three levers. I am working to clear debt and build savings while still fully employed. I am investing monthly — consistently, regardless of market conditions. I am building this online platform as a future productive asset. And I am planning to work, in some capacity, for much longer than the standard retirement model suggests I should.
The single most useful thing you can do this week is write down two numbers: how much monthly income you would need to live the life you want after 70, and how many years you might need to fund. Multiply them. That number — however uncomfortable — is the target your plan needs to reach. Most men have never done this calculation honestly.
The 100-year life is an opportunity, not a burden. But only if you plan for it with the time horizon it deserves. The financial models of the past were built for shorter lives. You need new maths — and a new mindset to go with it.
