There is an old joke about a nervous guy on an airplane and his seatmate who talks about how the plane won’t crash because it’s his lucky day. The nervous guy retorts, “what does it matter how lucky you are if one of the other passengers is unlucky?” (There are other variations on this joke, so just bear with me here.)
