My father put up an electric fense when I was 10 years, he said, "Don't touch this, it will hurt."
I waited a few days, but had to see for myself,,,,,yes,,,it hurt.
but I was 10,,,
My Grandfather used to raise cattle and had electric fences on the farm. I was about 10 when we were out near one of the fences and I asked him if the fence was on. He told me, "Grab it and find out."
