What is your Dayz superstition ?

What's the one thing you do because you think it brings you good luck on your run? I always get a black armband because I managed to kill three survivors in close combat the one time I wore a black armband. I also always have at least two knives on me, in case one breaks, because they are so useful. What is the thing you always do even though you know it might actually have 0 impact on your run?
