We have become very good at measuring the things that are easy to count. Cholesterol. Glucose. Blood pressure. Body fat. Sleep scores. Steps. HRV. These measures matter. But none of them, on its own, tells me whether a person can still live the life they want.
That is the distinction I keep coming back to when I think about healthspan.
Longevity asks how long we live. Healthspan asks what remains possible while we are alive.
Healthspan is not a better spreadsheet. It is retained capability.
What are we actually trying to protect?
If I am 75, I may care about my biomarkers. But I will care even more about whether I can climb stairs, travel, carry my own bag, think clearly, make decisions, see friends, play with grandchildren, work if I choose to, and live without having every ordinary task negotiated on my behalf.
That is why the emerging science of healthy ageing increasingly treats function as multidimensional. Physical capacity matters, but so do cognition, social participation, psychological wellbeing and independence in daily life.
It is a more useful target because it resembles what people actually value.
The measurement trap
Biomarkers are appealing because they look objective. A number gives us something to optimize. The danger is that optimization can quietly become the goal rather than the instrument.
A lower number is not automatically a better life. A higher score is not automatically more resilience. And an impressive dashboard can coexist with declining strength, poor sleep, loneliness, reduced mobility or a shrinking world.
I am not arguing against measurement. My work is built around measurement. I am arguing for a hierarchy: measure what helps us protect capability.
A better healthspan dashboard
I would want to know about cardiovascular and metabolic risk. But I would also want to know whether strength is being preserved, whether gait and balance are changing, whether sleep is restorative, whether the person remains socially connected, whether cognition feels stable, and whether daily choices remain theirs to make.
Some of those signals are clinical. Some are behavioural. Some are subjective. Together they tell a richer story.
This is also why longitudinal context matters. The interesting question is not merely whether a measurement is “normal.” It is whether a person is maintaining the biological and functional capacity that supports the life they intend to keep living.
The outcome is participation
I think the healthspan conversation becomes clearer when we stop asking, “How do I slow ageing?” and start asking, “What do I refuse to surrender unnecessarily?”
Curiosity. Creativity. Connection. Independence. Purpose. Participation.
The biomarkers are there to help us protect those things. Not replace them.
