Do you have an impressive collection of technical equipment and books, of high utility and/or historical value?
And you are getting on in years?
Well here's a thought. Please ensure you have made arrangements for the disposition of your possessions to others with the capabilities to value, use and preserve them, in the event you become incapacitated or pass away.

http://acms.org.au/, in recent days I've been helping deal with a storage unit full of items from a famous person. Due to age and ill health he's been unable to oversee his collection for some years. His family apparently stored all of it in some not-very weather proof space (a garage?) for a while, then finally moved everything to a commercial storage unit.

MOST things were still OK, but it seems some boxes were on a wet floor at some stage. These books are selected examples of the result. They are 'book bricks' - pages stuck together into a solid mass. The C++ one in particular is like concrete. (Quite ironic.)
