I like this idea. Five seems like a lot, but I like the general gist of it. One of my friends keeps a web page open called "Mori Clock" or something along those lines. You input your birthday and it shows you how many weeks, on average, you have left remaining. I'm not sure how useful it's been for his day-to-day experience, but it's an interesting idea, like yours.
