So yesterday, there was a sleep clinic documentary on the telly.
And one of the patients was a lad who just slept on and on and on and on and on and on, and whose parents were desperate, cos he couldn't get self-sufficient, cos he couldn't get up in the morning without a good dose of something drastic.
So they took him in, and put electrodes all over him, and woke him a couple hours after everybody else, come the next morning (cos he was still snoozing deeply, nevermind that the noise of the sleep clinic waking up usually wakes anybody in the various beds, early in the morning).
The output of the machinery attached to the electrodes said that yep, he's in deep sleep throughout the night.
What got me, though, was the extreme gratitude that the mother of said lad expressed, as the doc gave her a diagnosis: it was idiopathic hypersomnia.
Get this. They come in and tell the doc: "the lad sleeps too much, and we don't know why", and the doc (and his fancy lab) take all night (and a lot of machinery) to give a translation into latin, which basically says, "oversleeping, cause unknown"?
