Me to. I am a happy person because I am a pessimist. I know that everything that can go wrong - will. It is only optimists that are regularly dissapointed. So when things go wrong for me - I am merely able to shrug and smile because everything was exactly as I knew it would be.

That as my starting point means that duplicate BP's are printed in profusion and thinly distributed amongst pockets, wallets, handbags etc. The idea of one little battery powered electrial thing holding the open sesame to my next trip is simply a daft suggestion and inviting uneccesary risk.
