Clearly jazz aficionados are able to confront their own mortality. My wife has "encouraged" me to downsize my collection of LPs , 78s and CDs. I sell some stuff on Discogs and to a dealer friend. I've long since got rid of junk and slimmed my 78s down to about five hundred. I will only sell stuff on Discogs that is in excellent condition as I don't want to deal with complaints from buyers who allergic to the odd bit of surface noise. The majority of CDs/LPs in the departure lounge however go to a charity shop for the local hospice.
My other vice is darkroom photography, specifically film cameras of which I have very many. All vital of course and get used at least once a year. So basically my detritus spreads everywhere, hence I'm receptive to the requests to limit things..
