I object to the suggestion that hoarding is pathological.
There is something wrong with today's society of planned obsolescence and fashion, things should be able to be usefully kept, used, repaired if needed.

Mind you, I really should do something with the pile of mending and old sheets to be turned into pillow cases. And there is a pile of old TVs/video recorders/amplifiers etc - I think some of it works but I don't know which.
Video and Audio cassetes, some unused.
Books - ah yes. I'll start with books. Of course I'll have to reread each one as I decide. Then consult the rest of the family to see if they want them.
