Sometimes I will use something and realize I’ve owned it forever. It’s a nice change in our throwaway reality. I think my personal record is a bicycle multi-tool I got for one of my first bikes, ~25 years ago. Still have it, still use it. When it comes to electronic devices I have a Panasonic mini Hi-Fi from ~2005. Never felt like changing it.
What’s your record?
My usual drinking vessel is a souvenir cup from the 1992 Miramar Air Show. I still use a “boom box” style radio and clock timer from 1985 as an alarm clock. The tape player on the radio is long expired, but it still plays radio.
