When I was a kid I did odd jobs, and one of the odd jobs was cleaning out a semi-hoarder’s house after he’d passed away (iirc he’d lived through the Great Depression). Not like you see on TV, with the heaps and heaps of garbage. Maybe like your grandmother, tons of… basically well organized supplies and stuff.
I dunno. Toilet paper, some canned goods, lighters, I guess that stuff all lasts decades if stored properly. Takes up a lot is space, though, and your descendants might have to pay some kid to throw it all away if you don’t use it up in time…
But, some folks wished they were toilet paper hoarders during the pandemic I guess. Wonder what the kids of 2060 will be throwing away as a result of our life-experiences.
