10 questions
01
According to the essay, what question does conventional medicine fail to ask about a patient in their early forties who feels well?
AWhether they have an undiagnosed chronic illness
BWhether their body is being prepared for the person they will be at seventy-five or eighty-five
CWhether their blood results are being interpreted correctly
The essay opens with the question the author returns to: not about the patient's present, but about a version of themselves that does not yet exist – and whether the body they are living in is being prepared for that meeting.
02
The essay states that medicine at population scale is structured around:
AEvents – the fracture, the infarction, the diagnosis
BPrevention – screening for declining capacity decades before symptoms appear
CLongevity – maximising lifespan through early intervention
The essay argues that medicine is built around events and responds when something has gone wrong, but is not designed to detect the slow, silent erosion of physical capacity that precedes those events by decades.
03
What rate of VO₂max decline does the essay cite for sedentary individuals?
AApproximately 3% per decade
BApproximately 5% per decade
CApproximately 10% per decade
The essay states that VO₂max drops by approximately 10% per decade in sedentary individuals, and describes it as perhaps the single most robust predictor of all-cause mortality available in clinical medicine.
04
The essay argues that the public longevity conversation is almost entirely focused on:
AFunctional capacity in later life
BDuration – how to live longer, add years, slow ageing
CThe financial cost of age-related disease
The essay distinguishes between duration and capacity, arguing that the public conversation is about how long, while the clinically important question is what will you be able to do when you get there.
05
How many years does the essay state the average person in the UK will spend living with significant functional limitation?
A8–12 years
B3–5 years
C15–20 years
The essay states the average UK person will spend their final 8–12 years with significant functional limitation – unable to perform baseline tasks like playing with grandchildren, cooking, or walking without fear of falling.
06
The essay uses a financial metaphor to describe physiological reserve. What is the key point of this comparison?
AThat healthcare costs compound in the same way as financial debt
BThat capacity built in the thirties and forties is a deposit – and every year of neglect is a missed contribution that compounds in the wrong direction
CThat physiological reserve can be rapidly rebuilt at any age with sufficient financial investment in healthcare
The essay describes bone density, muscle mass, and cognitive reserve as deposits that compound over decades. The arithmetic is not forgiving, and it does not wait for the depositor to become interested.
07
What psychological distinction does the essay draw between maintenance and development?
AMaintenance is more effective physiologically but harder to sustain emotionally
BDevelopment requires more time and resources than most patients can commit
CMaintenance is psychologically defensive – fighting against decline – while development orients effort against stagnation, and maintenance occurs as a side effect
The essay argues that patients who sustain change over years are almost never those trying to maintain. They are those trying to develop – pushing off a horizontal line, not a descending one. The maintenance occurs as a side effect.
08
Which of the following does the essay identify as the most validated physical marker of all-cause mortality in published literature?
AGrip dynamometry
BDead hang duration
CWall sit endurance
The essay describes grip dynamometry as the most validated physical marker of all-cause mortality in published literature, citing the European consensus sarcopenia floor of 27 kg for men and 16 kg for women.
09
For a desk-based professional, the essay argues that meeting today's physical demands is:
AA reliable indicator that their physiological reserve is adequate for later life
BNot evidence of capacity – it is evidence that today's demands are low
CSufficient for maintaining health until retirement age
The essay makes a pointed distinction: the absence of symptoms is not the presence of adequate reserve. For someone whose daily demands are minimal, meeting them says nothing about the trajectory they are on.
10
The essay's central argument is that the question of what later life will contain is answered:
AAt seventy, when functional decline becomes clinically apparent
BAt the point of retirement, when physical demands change
CQuietly and incrementally at forty, through effort that is unglamorous and largely invisible
The essay's closing argument: capability is built across decades, in the period when it does not yet seem urgent. The question is not answered at seventy – it is answered, quietly and incrementally, at forty.
