How long has it been since you did absolutely nothing? I know exactly how long it's been for me. I know how long it's been since I had every need met choicelessly from someplace outside me, without my having to ask. And that time I was floating, too, and the fluid was warm and salty, and if I was in any way conscious I'm sure I was dreadless, and was having a really good time, and would have sent postcards to everyone wishing they were here.
