Agreed in general, but in this case that's exactly the story. He discovered his apnea is cognitive ("central"), not due to his throat geometry. If we're ever able to figure out and solve the root causes of cognitive problems like that, it will be amazing, and we should, but I don't think we're there yet.

That's because you have OSA (obstructive sleep apnea). I (OP) have central sleep apnea, there is no obstruction, its related to the nervous system. I am already very lean (I run ultra marathons as a hobby).

The downside of getting diagnosed is my life insurance company dropped me.
