The Slotin incident happened in 1946, after WW2 had ended.
Vs. if your day job routinely involves high voltages, roofing, heavy equipment, or other "one stupid slip, and your life is effectively over" situations, then you have a rather different outlook on this.
Despite having been in all kinds of alpine rock climbing and international downhill ski racing competition experience, or perhaps because of it, that was just a hard NOPE. I think it was just the intense awareness that, once a slip starts, there was no recovering or stopping before the ground. The weird thing is just how totally casual he was about it, even seeming to think my question about protection was a bit odd.
I'm just damn fortunate to have the option, especially considering the statistics for roofing work.
It always seemed barn raising events were a very effective and efficient way to build community infrastructure. But a death or crippling per barn is a damn high cost in blood!
