One way to reduce the neurotic effects is to carry a 45 ACP on the hip always. A short sword on the belt would also serve to ease unease. Neither will stop a truck bomb, but odds are you will go your entire life without being blown up by a truck bomb and you will not have to worry about being taken captive and have your head sawn off on video since you will either not be captured or will not be captured alive so long as you can get your sword arm loose.
One of my favorite "All in the Family" episodes was when the asked Archie to go on T.V. basically as the average joe, and talk about his views on certain issues of the day...
After he gets home, he says to turn on the tube, so they could watch how he did... So they pan the camera over to the T.V. and there's Archie sitting there, with his hair slicked down because of the makeup people, and talking as only he does, he says (in his unforgettable Bunker voice...) "And you wanna tawk about hijakins? I got a solution that would put an end ta' dees' hijakins tomora'... My answer, Ya arm all da' passengiz... Problem solved..."
