Oh, geesh, don't tell me that.
My 15(?) year old refrigerator has been giving little hints that it's on its last leg, as is my 15(?) year old dryer. When I replaced its matching washing machine recently, I debated buying the set, but wanted to wait until it actually died. And my water heater...it's at least 25 years old...
I dread buying new appliances EXACTLY because of what you said. It used to be that major appliances lasted decades. Now? Not so much. And they're ridiculously expensive, to boot...
