Peter, I know exactly which 5 mn you mean, how very well phrased! I even spend them dithering about taking a shower, which I adore doing, I just apparently either remember being a small child and hating it, or else I must hate getting into the shower, in contrast to being in one... Or calling an author (even one I know I'll enjoy talking to)... or actually DOING the shopping for something to wear to my niblings' mitzvahs next month (I like shopping, why don't I just DO it?)...And you're right, it isn't inertia so much as leftover procrastination momentum, or something! Any physics majors want to take a swipe at the terminology?
