What are you going into? Subs, carriers, aviation, electronics, what? My brother was in nuclear power on board submarines. Knew how to fix plumbing associated with the cooling systems and heat exchangers. He's bald, but doesn't glow in the dark. My dad was an avionics technician, back when avionics was vacuum tubes and point-to-point wiring with discreet components. They had capacitors and resistors and stuff in their circuits.
