These are the issues they're worried about? None of the numbers I saw while scanning look particularly worrying, and I doubt there's ever been a country on the face of this planet for which you wouldn't have been able to produce a similar list of issues of this magnitude - including past Norway.
They're worth paying attention to, but not sounding the alarm bells over.
That's because there is a default bad assumption that because they are so wealthy that no problems should exist, similar to how very rich people are seen. Looking at other wealthy petro-states (and people) around the world, that's clearly not true.
But relatively speaking I don't think there's a country that wouldn't trade most of their problems for Norway's, with the possible exception of their aging population.
Poorer health might be concerning, but is likely the result of the population growing older. More children would help make the numbers look better, I suppose, but, statistically, only poor people like having children.
For one thing it's clearly a problem if you include the environmental impact of constructing those bridges to nowhere.
