Interesting.
I always keep these things, passport particularly, very close to hand but not necessarily on my person throughout. But then I always assume nothing will go wrong and, so far, it hasn't!
Perhaps I should re-think.
Actually, one if the most important possessions is Little Fruitcake's skyflyer book, which is now 4 books stapled together. That would be a very sad loss - so far the crew have never failed to bring it back in one piece! ^
