I've heard that Winston Churchill did much of his work in bed or in the bathtub — reclining, in both instances. Not that I intend to emulate that great man in all his habits (as if I could), but I have grown fond of working in a reclining position.
There is much to be said for it. Comfort, first of all. And with laptops as small and slender as they are now, it's easy to do.
I even think thoughts may flow differently when one is lying down rather than sitting up. They're more fanciful, less rule-bound.
Of course, the modern workplace is not set up for this, but if I was in charge, offices and cubicles would be outfitted with chaise longues as well as desks.
The only occupational hazard would be falling asleep. But it's a small price to pay.
