01 · Where are we now?
Lifespan and healthspan
are not synonyms.
Eurostat's 2023 activity-limitation measure estimated 81.4 life-expectancy years and 63.1 healthy life years for the EU; 81.9 and 59.0 for the Netherlands. Healthy life years are not WHO HALE.

Life expectancy versus healthy life years
| Geography | Life expectancy | Healthy life years | Difference |
|---|---|---|---|
| EU27 | 81.4 years | 63.1 years | 18.3 years |
| Netherlands | 81.9 years | 59.0 years | 22.9 years |

Comparability: healthy life years combine life tables with self-reported activity limitation. National question wording and private-household coverage can affect levels.
Longevity and capacity
World life expectancy reached 73.48 years in 2024.
Healthy years and access
EU definitions permit useful comparisons with explicit survey caveats.
Mechanism comparison
Japan and United States show different longevity and physician-density profiles; not a ranking.

02 · What direction are we moving?
Global lifespan recovered.
That is only one outcome.
World Bank data place global life expectancy at 73.48 years in 2024, above 72.58 in 2019 after a pandemic-era drop. This does not establish improving chronic or mental-health burden.

03 · Who benefits or carries cost?
National averages hide
access and burden.
237.7 avoidable deaths per 100,000 people under 75.
150.9 classified as preventable and 86.8 as treatable. Different mechanisms; no double-purpose causal claim.
3.6% reported unmet medical need.
6.0% among people at risk of poverty versus 3.2% among others. Measure combines cost, waiting lists and distance.
Waiting-time boundary: administrative targets, patient clocks and procedure lists differ. This brief exposes missing comparability instead of ranking systems.
04 · Competing explanations
Outcome, system and claim
belong in separate lanes.
What happened?
Lifespan, healthy years, mortality and disease burden.
Could care respond?
Access, waits, workforce, capacity and spending.
Who is exposed?
Behaviour and exposure are neither destiny nor system outcomes.
Does intervention work?
Benefits and harms for a defined population.
What is measured?
Prompts and sensor readings are not clinical benefit by default.
What remains hypothetical?
No human healthspan claim without demonstrated clinical evidence.
05 · What would change our conclusion?
Healthy years must improve
with stable definitions.
- Healthy life years rise faster than lifespan across repeated comparable observations.
- Preventable and treatable mortality fall across income groups and regions.
- Unmet need and stable-definition waits fall while safety holds.
- Workforce capacity, retention and geographic distribution improve together.
- AMR resistance falls under stable testing and surveillance coverage.
WHO GLASS covers more than 23 million confirmed infection episodes.
Reported by 110 areas for 2016–2023. This demonstrates surveillance reach, not a comparable global burden trend.
Better prevention may compress morbidity; spending alone cannot demonstrate it.
Automation may release clinical time if real access, workload and safety outcomes improve.
No defensible global composite joins outcomes, access, workforce and individual risks.
