When I got to the power stations, I got used to heights, like walking out of a lift onto a grid mesh floor 65 metres above the deck...would give me a little rush, but that's about it.
15 years ago I climbed the chimney stack at Mount Piper, 250m high at the top, and internal ladders and worksafe legal platforms to get there.
Since having children, I'm much more aware/scared of heights. Recent project had a 100m diameter setof scaffolding, around 20m off the deck. I could walk around, but the planks moved some, and I was super cautious.
Watching that video, my palms were dripping sweat. Not just damp,beading and dripping.
