Not applicable. I read through most of the DSM-IIIR in high school (long story). That's when I decided I wasn't interested in psychology. It was fascinating, but when comparing the categorizations from version to version of the DSM, it became clear they were totally making up bologna for a large part of their profession. All the DSM did is stipulate what kind (and how much) of bologna most of them agreed on at any time- probably to aid in billing the insurance companies- nothing more.


Regarding my "addiction" not only is it NOT cluttered, I have every calculator item, every serial number carefully tested, cataloged, along with purchase date / price, notes, etc..

I have also bought and labeled special boxes for accessories for each series.
It's as precise as I can be given my other computing interests and time commitments.

On a related note: It's very handy to have a Calculator collection when I travel. I detest small talk with strangers on the plane/train/bus, so if someone asks what I do, I say "I collect HP calculators and really enjoy writing mathematical algorith...."

Eye contact breaks, throats clear, and I not a single word is said to me the rest of the flight. Blissful, really.
