When you think really hard about a very, very complicated problem at a rapid rate for a short and intense period of time and then, thankfully, come to a satisfactory answer after which you are complete spent and brain-dead as if "catching your breath".
The reason I'm lying down on the floor in my office is that I found a fatal flaw in the software and had a brain sprint. I think I'm done for the day.
