I have a refrigerator from around 1988 or 1989 that still works perfectly. Around 1999, it stopped working, so we bought a new one. We didn’t throw away the old fridge because we used it to store plates and cutlery, but we were sure that it was completely broken. Then, last year, a technician saw it and told us that only a component needed to be replaced for it to work again. Lo and behold, the damn thing was revived, and after a two-decade slumber it worked again as if no time had passed.
