Collecting Razor Blades
I have the ability to become interested in almost anything -- I suspect it's just a normal human trait. I once read an entire book about raising turkeys as I didn't have anything else to read and the book itself was well-written. So it happens like this: normal curiosity+chance encounter=transient interest. What do you have to add to that for an obsession to start? normal curiosity+chance encounter+emotional involvement=obsession? nc+ce+genetic predisposition=obsession? I don't know. It might have something to do with nest-building genes -- or maybe control. nc+ce+control freak=obsession. Uh... I doubt that, somehow.
