Surprise device lifespan

[jfkbengals]

2 years ago I replaced a 1986 Whirlpool dryer, a 1982 range, and a 1977 GE refrigerator. The dryer was replaced because the one part 1 needed was no longer available. The stove only had two working elements because the controls went out. They were still available, but were $200 each. At $400 it was better to replace it. The fridge worked fine. It was not my choice to replace it...

Last year I replaced 2 water heaters. One was 18 years old, the other was 20.

I have a radial arm saw, canister shop vac, lathe, electric drill, and upright freezer that I inherited from my father. All of those items are older than I am and function perfectly. For the record, I am 45...
