According to the article, it’s the exercise that’s so beneficial for sleep quality that drugs might no longer be necessary, not “being in shape” but “getting or staying in shape”. Makes sense to me.

I like that the results are from a longitudinal study that spans more than 30 years and involves 30,000+ participants. That’s a better standing than most studies have.

Being in shape and staying in shape are the same thing. Fit people aren’t magically fit. It’s something you work on daily or almost daily

In the long run, you are absolutely correct.

There is a transitional period of a few months to a couple of years where you’ve stopped training but haven’t completely lost the adaptations to strength and endurance yet, so perhaps you could tell the difference during that time period. I doubt this type of study can tease that apart, though.

Agreed, and it would definitely be unethical to create those conditions intentionally.
