Some people (mostly men) actually enjoy dangerous situations. Especially if there is a purpose for the danger. Look at all the people doing extreme sports. The military, police, and fire fighters are the main jobs left for people like that. There used to be a lot more.

Apropos of building suspension bridges, different people apprehend the danger of situations differently. I recognized this when I read that Alex Honnold doesn't like to be on ledges. When I climb, I love ledges and given about 12 inches of ledge I would host a party. But I never could climb without a belay the way Honnold does. I could never jam my fist into a crack in granite and just hang from it. ETA I don't have Honnold's talent.

Also I think when people are in a hard-core feed-my-family situation, they dig deep into their resolve, follow the safety rules, and avoid looking down.
