Until recently something I never gave any thought to at all is the level of skill involved in getting in bed, lying there, and going to sleep.
How hard can it be, right?
Well. Turns out, there are any number of ways you can get it wrong. Any number.
Personally, I prefer it to be lying down flat, on a soft surface – that would be a bed – with a pillow and blankets and nothing else arranged around the place.
