I had thought I’d been sleeping unduly long — 9 to 11 hours at times if I can get away with it — until I read a report in the weekly science section of The New York Times on the so-called glymphatic system, which takes out the trash, as it were, from the brain while one is in Never-Never Land.
“So what is removed from our brains as we sleep?” I asked Mary, who is as much of an insomniac as I am a narcoleptic, this morning.
“I don’t know,” she said. “Read the article. I’ve saved it. It’s in the computer room.”
