No, I'm serious, 30 hours of 1000 ways to die is terrifying. Bunch of electrocutions, where they show the progression from a little burn spot to massive tissue damage and death a week later. Fall victims where you can't hardly tell who they were with up close shots of the damage. Imagine the worst climbing incidents shown here, but in a classroom setting where they have long discussions of the physiological damage done complete with super up close pictures and video on a projector screen. Then to walk into a powerplant or chemical plant with a bunch of guys working everywhere and all sorts of terrible stuff everywhere you look, and they gotta climb scaffold 100 feet in the air and start taking apart lines with chemicals in them. The trade itself is scary enough, add watching a real life horror movie that goes on for a week on top of it, and it makes them reconsider doing this job lol. When I started I had a horrible fear of heights and a bit of claustrophobia on top of it, but i was lucky to work on projects where i could ease up to it and get used to it. In time i came to enjoy high work and confined space work, and am kinda known for both. I've done xray welding on rope access, where most fitters would never go on rope ever. Ironically walking i beams and confined space work is considered normal tho hahahahahaha.
Edit: 100 percent tie off isn't common either, and the heights you can be climbing ladders and stuff is kinda ridiculous. It's getting more and more that way, but it isn't there and likely won't ever be.
