Healthy life expectancy
Healthy life expectancy asks how many years people might expect to live in good health. It is a population measure and is not estimated individually in V1.
A long life and a healthy life are related questions, but they are not interchangeable.
Why V1 does not manufacture a personal “healthy lifespan”
WHO’s HALE estimates combine mortality with population health-state data. Translating a national HALE value into a personal age would require another validated model and much more clinical information. YouLiveLong therefore provides population context without presenting a false personal number.
What HALE can still tell us
At the population level, the gap between life expectancy and healthy life expectancy describes years lived with some degree of health loss. It is useful for public-health comparisons, not a countdown for an individual.
