People won't listen to "if you walk under a ladder you might get hit by a paint bucket" but they will listen to "if you walk under a ladder some nondescript aethereal force will give you bad luck". What is wrong with our brains.
absolutely, yeah. there's still a lot of construction folks/builders that refuse to do it. usually the same folks that have superstitions about tools (like never hand someone an unfolded pocket knife, no matter how safely you do it)
There's a really weird thing in the Southeastern US where people will hand you pocketknives with the blade out always and you can't hand it back closed. I don't understand it.
