I've gotten amazingly few shocks, considering my history of working and playing with electricity.
I am 53 years old and can probably haven't received more than a dozen shocks, most of them on the light side.
The worst ones we used to get as kids were from a defective refrigerator, right across the chest when we touched a steam pipe at the same time as the fridge handle.
Not knowing anything about electricity, my parents didn't realize there was anything wrong with the fridge, so they just taped the handle with electrical tape.
This was no leakage current. It was the full 115V. I recall once having to push a friend off when she got hung. We were very lucky no one was seriously hurt or died!
If there had been GFCI in those days, none of that would have happened. We would have understood that there was a problem because the GFCI would have kept tripping, and called an electrician, who would have told us to get a new refrigerator.
I guess my mom or dad should have called an electrician anyway.
We learn from our mistakes, as long as our mistakes don't kill us!
