On rare occasions, I read something so powerful I have to share it here.
Today is one such occasion.
Dan Haylett is one of my favorite writers, and a heckuva nice guy. His podcast, Humans vs. Retirement, is the #1 retirement podcast in the UK for good reason. (Sign up for his free weekly email here)
While his podcast is great, I can’t get enough of this guy’s writing. Every week, I read his email as soon as it arrives. Recently, he published “Your 12 Good Years” on his Substack feed. The following comment from a reader is indicative of how good it is:
“Maybe, if not probably, this is the best retirement article I’ve ever read.”
As soon as I read it, I asked Dan if he’d allow me to republish it here.
Fortunately, he said yes.

Your 12 Good Years
Here’s a number that should change how you think about retirement: 12.
Not 30. Not 25. Not even 20.
12.
That’s how long the average healthy 60-year-old has before their mobility, energy, and independence start to significantly decline. Not before they die… before life gets noticeably harder.
You might live to 90. You might even make it to 100. But the version of you that can hike the Inca Trail, chase grandchildren around a park, travel independently, or even just get through a full day without fatigue? That version has a shelf life.
And it’s shorter than you think.
The Data Nobody Wants to Hear
I want you to be clear about what I’m talking about here. This isn’t about morbidity or scaring you into action. This is about healthy life expectancy, the years you have before chronic illness, disability, or physical limitation becomes a daily reality.
In the UK, a 60-year-old man can expect to live, on average, to around 84. A 60-year-old woman to around 87. Those are the headline numbers. The ones that make retirement planning calculators tell you to prepare for 25-30 years.
But those numbers don’t tell you that most of those later years aren’t healthy years.
Data from the Office for National Statistics shows that healthy life expectancy (the years lived in good health without limiting illness or disability) ends much earlier. For someone who is 60 today, you’re looking at roughly 12-15 more years before health limitations start to intrude in meaningful ways.
That doesn’t mean you drop dead at 75. It means that by your early to mid-70s, things start to shift. Energy declines. Recovery from illness takes longer. Long-haul flights become less appealing. All-day adventures turn into half-day outings. The body you’ve been living in for six decades starts sending you clearer signals about what it will and won’t tolerate.
Research on retirement spending patterns backs this up. The Institute for Fiscal Studies found that retirees’ spending on travel and leisure increases through their 60s, peaks around age 75, and then declines, not because people run out of money, but because they run out of the physical capacity to do the things that money would buy.
You have more time than you have energy. More years than you have vitality. And if you don’t understand that distinction, you’ll waste the good years preparing for the declining ones.
What “Good Years” actually means
Let me be specific about what changes.
In your 60s and early 70s, if you’re reasonably healthy, you’re still you. You can travel. You can be spontaneous. You can handle long days. You can manage your own life without help. You have the energy to start new projects, learn new skills, and take on challenges.
You’re not invincible (you’re not 30), but you’re still fundamentally capable.
By your mid 70s and into your 80s, things shift. Not dramatically. Not all at once. But gradually, consistently, undeniably.
You might still travel, but not as far or as often. You might still be active, but you need more recovery time. You might still be independent, but you start needing help with things that used to be trivial, like changing a lightbulb, carrying heavy shopping, and navigating airports.
The things you do become smaller. More local. More cautious. Not because you’ve lost your spirit, but because your body has started setting the terms.
And this isn’t pessimism … it’s just biology. Muscle mass declines. Bone density decreases. Balance becomes less reliable. Chronic conditions accumulate. The resilience you took for granted starts to fray.
None of this means your later years are worthless or joyless. Many people find deep satisfaction and peace in their 80s and beyond. But they’re different years. Quieter. More reflective. Less physically expansive.
The good years, the ones where you still have the physical capacity to do most of what you want, are finite. And they’re shorter than the total lifespan numbers suggest.
The Spending and Activity Decline
Here’s where this gets practical.
One of the most robust findings in retirement research describes how retirees’ spending patterns change over time.
Spending is relatively high in the first few years of retirement, the “go-go years.” You’re active, you’re travelling, you’re finally doing all the things you deferred while working. Then it declines through the middle years, the “slow-go years,” as energy and interest naturally wane. And then it potentially rises a bit again in very late life, the “no-go years,” as healthcare and care costs may come into the equation.
But here’s what that misses … the decline in spending isn’t driven by frugality. It’s driven by physical limitation.
People in their late 70s and 80s aren’t spending less on holidays because they’ve suddenly become careful with money. They’re spending less because long-haul flights are exhausting. Because hotels without lifts are a problem. Because they don’t have the stamina for full days of sightseeing anymore.
The spending decline tracks the activity decline. And the activity decline tracks the erosion of those 12 good years.
The Trap of Deferral
The cruel irony is that most people spend the first decade of retirement living as they did in the last decade of work: carefully.
You saved for 40 years. You delayed gratification. You were prudent, responsible, cautious. And that got you here. It built the nest egg. It secured your future.
But if you keep living that way, you’ll waste the very years you saved for.
I see this constantly. Clients in their early 60s, financially secure, agonising over whether they can “afford” a holiday. Whether it’s “sensible” to upgrade the car. Whether they should help their grandchildren with something meaningful.
They’re optimising for a 30-year retirement. Planning as if every year is equivalent. Treating their 60s the same as their 80s.
But they’re not the same.
Your 60s are not a rehearsal for your 80s. They’re the main event. And if you don’t spend (not recklessly, but intentionally) during the years when you can still fully enjoy it, you’ll reach 78 with a big bank balance and a long list of regrets.
The things you can do at 65, you often can’t do at 75. The trip that sounds ambitious but achievable today might be off the table in a decade. The time with grandchildren while they’re young and you’re energetic doesn’t come back. Continue Reading…
