Just in the last month I used some sandpaper that had sat in a box for several years, pulled a ten year old DVD off a shelf and watched it, re-read a book from my childhood and connected an obscure audio adaptor that had been untouched for at least five years.
Earlier this year I played games on two different games consoles from previous decades and reactivated a Raspberry Pi from a previous project into a new one. I pruned a tree and dug a flower bed with some tools that were recovered from a grandparent's house after sitting untouched for well over a year.
If everything in your house that's more than a year old is worthless, maybe you're just buying things which are worthless from the beginning.
