Happy 45th, to the best oven ever.
We recently noticed visitors to our apartment are regularly impressed (good? bad?) by our oven-- it's the original for the apartment (which was built in 1961), and after yet another visitor asked us yesterday, "does it really still work?" I found this article listing ovens as lasting an average 20 years. Our oven turns 45 this year! It's true. It's really, really old for an oven.
On the flip end, a fridge is supposed to last 18-20 years, and our last one didn't quite make it. We replaced that one last June, when it was about 15-17 years old.
