Which undercover position do you think best suits my interests?

Of the ones listed here, which do you guys think would best suit me? I identify with the game Resident Evil 4, where fear is around every corner and you never know when danger will strike. I also watched the Exorcist and could feel the same tense fear during certain scenes. I practice Tai Chi and I swim, but I don't like to do pushups and running. What do you guys think would suit my interests best? Thanks!
