I must admit, when I have to fly, it's all about me It doesn't occur to me that I might get blown up that day. I'm more focussed on how can I pack to get through security most easily, when should I leave to avoid rush hour traffic, how fast can I get to the lounge, will my upgrade come through ...

On the plane during take off and landing I may have a fleeting thought about the skill of the pilot, the weather, or the technicians who service the plane, but it's never "is this the last hour of my life". And it's never scouting out other passengers for suspicious behavior (and what do I know about suspicious behavior anyway?)

Life is already too short - you can't stress about the things you can't control.
