Great post, Elizabeth!
I also routinely replace dupes live, even showing my 16yr old daughter while doing it. Yet I remember as a kid I was fixing an old transformerless 5-tuber in the basement, poking around live with my requisite one-hand-behind-my-back to avoid closing a circuit, and suddenly woke up 10 minutes later 10 feet across the room, on the floor with a bruised head. Next day I noticed a small red mark on my neck. Later I returned to my basement lair, finally noticing the dangling piece of 16AWG clamped to the cold water pipe! "How convenient!", I had thought when installing it some months before....
