THINGS I DID NOT DO WHILE IN THE NAVY TO REDUCE MY CHANCES OF ACCIDENTAL DEATH

Call me risk-averse.
  1. Sky-diving.
    There are opportunities. I did not take them.
  2. Swim calls.
    Exceedingly rarely a ship captain decides to let the crew go swimming in the ocean. I took note that there is an armed "shark watch" stood up during these times, and declined.
  3. Helicopter rides.
    Pilot friend: "Want to take a ride?" Me, looking at the vast expanse of water: "No, thank you."
