There is some new scientific finding that in deep sleep, fluids from the brain drain out and if that flushing doesn't happen, it might lead to Alzheimer's disease.

You should at least monitor your deep sleep using a smartwatch. Less than 1.5 hours and I would be worried.

Thanks, I am aware of reduced cerebrospinal fluid flushing as well as the increased neural inflammation in general and I am trying to compensate for that as best as I can.

I am not too worried about Alzheimer's as it tends to start pretty late in life (I think average onset is around mid-60s?). If I get that and we don't have a reliable cure by then, I wouldn't really mind ending it quickly after getting the diagnosis. I'm a bit more worried about heart disease as that tends to hit earlier.
