Your healthspan may be the most important asset in your financial plan, yet it's often the one we invest in the least.
It’s completely natural to obsess over the numbers on our investment statements. We track the growth, review our asset allocation and carefully project how long our capital will last. This is good practice and solid foundational planning, but it’s not the whole story.
What if, in all our careful calculations, we’re overlooking the most critical asset of all?
Financial stability is only the foundation
Carrying on from our recent Insights pieces, based on John Coleman’s 'Good Money', we’re reminded that financial stability is just a foundation. The goal is human flourishing, the focus of the Human Flourishing Program at Harvard University.
The second domain of this flourishing framework is mental and physical health. It serves as a gentle reminder that a well-funded retirement account is only as valuable as our physical capacity to enjoy it.
Thanks to modern medicine, our generation is living longer than ever before.
Lifespan is not the same as healthspan
From a financial planning perspective, this means our money needs to stretch further. But there’s often a blind spot in how we think about these extra decades. We tend to focus entirely on our 'lifespan' (how long we’ll live), while completely neglecting our 'healthspan'.
Healthspan refers to the number of years we remain active, independent and free from chronic diseases.
We often spend our peak earning years sacrificing our physical well-being to build our wealth. We tell ourselves that we’ll finally focus on our health, get outdoors and reduce our stress levels when we eventually retire.
But our bodies don't wait for our bank accounts.
Physical capital doesn’t automatically compound over time – it naturally depreciates. If we wait until retirement to start investing in our vitality (physical and mental), we might find that the damage is already done.
Small deposits into your physical capital
It’s incredibly helpful to reframe how we view our daily habits.
Stretching for a few minutes, drinking fewer stimulants and eating a nutritious diet aren’t just lifestyle choices. They’re literal, daily deposits into our physical capital. Just like the money in our portfolios, these small deposits compound powerfully over decades.
They build a robust physiological foundation that delays illness and preserves our mobility.
Protecting tomorrow’s wealth today
From a purely economic standpoint, investing in our healthspan is one of the most effective wealth-protection strategies we can implement. In our later years, chronic healthcare can easily become our single largest expense.
By staying active and healthy today, we help protect our future capital from being entirely consumed by medical costs tomorrow.
More importantly, true wealth is having the freedom to live with purpose alongside the people we love. By treating our physical and mental well-being with the same care as our investments, we ensure we have the vitality to live the life we’re saving for.
When financial freedom meets physical freedom
Consider a couple who spent 30 years saving for retirement. Their plan is simple: travel locally, walk with their grandchildren and stay in their own home for years. Financially, they are prepared. But in their early sixties, one partner develops mobility problems that make stairs difficult and long outings exhausting. Suddenly, the issue is not whether they can afford the holiday, but whether they can physically enjoy it. Strength training, preventative care and attention to everyday movement might not have eliminated every risk, but they could have helped preserve more independence. This is where healthspan becomes practical rather than theoretical. The return on those earlier investments is measured in choices retained: joining the family trip, carrying the groceries, playing on the floor and remaining an active participant in daily life.
