I completely lack the 'critical self narrator' that many people report being distressed by. If I make a bad decision there is nobody 'punishing' me for it internally. I also feel like I am better than average at very stressful dangerous situations - i find that i dont particularly analyze things in the moment, or at least the conscious part i aware of doesn't. I just act on 'autopilot' if that makes sense.
It does have an enormous mountain of downsides, though.
