Eagle, I think you might present SWMBO with the Collectors Theorem which I have mentioned in these forums in the past, albeit in simpler terms:PS: I think SWMBO might be right..."I have a problem with my incessant shoe purchases!" LOL
If N is an element of the set of positive real numbers, R+, and N is the total number of objects in your collection at time Tc, the current point in time, then the total number of objects you need at the next point in time Tc+1, is invariably N+1.
Proof: The proof of the theorem is self-evident. We will leave it to the reader as an exercise.
This mathematical mumbo-jumbo will convince most people that there is at least a modicum of scientific legacy to a collecting obsession which the social critic and cultural observer Dave Barry has suggested borders on madness.
That dodge about the proof, by the way, was/is a standard one in textbooks of mathematics, and one which I used to run into often as a student of the subject. It is likely to infuriate above-mentioned SWMBO. (Please don't tell her I put you up to this defence, she might extend her displeasure toward poor old me).
As you can see, today I have time on my hands, LOL.
