I have plastic sandwich bags full of 40 years of broken beaded necklaces, beads for necklaces, things that could be made into necklaces, and missing-one earrings which could be turned into pins or necklaces.
I have 30 years worth of photos and negatives - some of which were properly put in books which disappeared in moves or got rained on when house leaked.
I have a giant cardboard box full of newspaper/magazine cutouts which when scanned and OCR'd could be a giant cookbook. I used to put them in scrapbooks back in the day before kids.
I will do these things when heaven forbid I break both legs and have to sit still.
