If you think most farmers, construction workers, factory workers, and so on would press blue then you might want to actually get to know some of them and put them to this test. I don’t think many of them would willingly risk death on something so trivial as a button press. I’ve seen guys get rescued from falling off roofs but as written I don’t think many of the guys running to get their buddy out of his harness and on the ground are going to pick blue if you present it in a really clinical sense.
