agree with rgbrock1 - a close friend has had weird 'seizures' for about 5 years, after 2-3 months, basically out of the blue. Well, probably emotional stress - very good things or very bad things, but nothing excessive (to someone who's not in his skin). The first time I was sure he's gone mad. The doctors were sure it was a stroke. (By now they THINK they know what it could be, one of the rare things, not mental and he's ok between the attacks.) For me this bomb-talk totally makes sense - surely that's an issue for pilots. The person I know goes outside and starts looking for his business car he had 30 years ago, for example, and claims he has to do something he did then.
Things are complicated sometimes. Not always, of course, but still.
