I'm the one who is awake by the fire when the sabretooth shows up at midnight. I'm the one going around telling everyone to get outside, the house is on fire. I'm the one who is suddenly at the bottom of the small cliff, still steaming and naked from the hot tub, doing first aid assessment on the partier who fell off. I'm the one who burns for 14 hours and gets the team to push that working build out minutes before going live.

There's dopamine in there. We're starved for it daily so we can go hard in some way when it counts.

It makes sense, but it also makes sense to design society so that situations where it's helpful happen as rarely as possible. If some people are predisposed to being a good firefighter, it doesn't negate the fact that you don't want buildings to catch fire in the first place, so you still want to teach children not to play with matches, teach adults not to keep lighter fuel near their heater, and ban companies from selling combustible cladding to insulate tower blocks. Prevention is better than cure. You just then have a load of people who aren't great at being anything except a firefighter, ready for fires that never happen, and under the current system, forced either into jobs they're bad at, or into chronic stress to get consistent productivity.

It's a feature.
