So from the data, prior to covid-19 Danes had gained about 3 and a half years of healthy life, and an additional year of unhealthy life.
It makes sense that Healthspan and lifespan are well-correlated, as most of the ways we have of extending lifespan do so in a way that makes you clearly healthier (such as preventing chronic diseases).
Contrast this with Denmark's lifespan growth over the same period, of 76.8 to 81.4 (+4.6 years) https://ourworldindata.org/grapher/life-expectancy?time=2000...

That said, it is true there is a bit of an increasing gap. This isn't just in Denmark, it's global - lifespan rose by 6.4 years from 2000-2019 while healthspan only increased 5.3 years. https://www.who.int/data/gho/data/themes/mortality-and-globa...
