I've been in some life or death situations on construction sites, not nearly the same as what you go through I know. However, my mind does a very similar thing during these times, where it feels like time slows and I can see everything and process much faster.

I've been told by professionals its adhd, and I'm definitely not a psychopath. Judging from your descriptions, and your spatial awareness and reactions, I'd say you might want to look into that. Sure, you come across a bit coldly logical, but that's the job. You don't come across as emotionless, just controlled and focused.

Knowing the ins and outs of your most powerful weapon is important. You've obviously found a job that suits you, but knowing just how far and why you can push yourself would be handy especially against previously unknown enemies.
