Those are some terrific thoughtful answers however not correct. I'll tell you.
I am doing some spreadsheet work on college football. I am crunching the numbers from last year's spreadsheet and integrating them into my existing data and tweaking my strategies for the coming season.
That's right I am doing it now, comfortably in advance, instead of my usual 3.5 seconds before the season begins. I told you it was smart.
In fact I am taking periodic breaks just to strut around my apartment with my chest puffed out, singing, I AM SO SMART! I AM SO SMART!
That's what I'm doing.
