Sleep apnea - it's weird how you often don't notice/understand it until an external observer who has seen it before tells you what's going on. You just feel very slightly more tired each day. You randomly microsleep without realizing. It's quite insidious. It's obviously very dangerous if you drive a car.
This area needs much more awareness (and tech-based
"disruption" - especially in detection, but also in making CPAP treatment more affordable and accessible).
