Healthy life years at birth is not life expectancy!!! Their life expectancy is much higher. And this can be a noisier metric because there is a lot of subjectivity involved as it relies on surveys and shit and not just death data. Idk the methodology to this one and I'm too lazy to look but yeah probably a lot of long covid shit going on there. But I doubt they did any follow-up on those surveys - covid often disabled people for a few months at a time and many of those symptoms eventually resolved for most. So I would expect some noise because of this, but I'd also expect some decrease in healthy years just bc of a novel virus ripping through the population.
They let it rip during a time where the disease was far more severe and immunity was minimal so it would track, I just wouldn't draw conclusions based on this data!
