Killing/rescuing people with your brain instead of bullets and/or creating/exploding structures.
Join the Army. Become a Combat Engineer Sergeant.
Enjoy getting told by your superiors that they are afraid of sitting in the same room with you, because your thinking cap gaze looks like you are always plotting to kill them in the most sophisticated and fun way imaginable. Never say a word, just give them a big friendly smile in return.
Leave with a treasure trove of abilities useful for the rest of your life, or to simply troll your neighbors, and give lifelong work to a local psychotherapist.
Big friendly smile. Two thumbs up.
