The streets may have been dirty and graffiti-infested but, by and large, they were safe. Aids, mad cow disease, road rage and deep-vein thrombosis had yet to be discovered. If you caught a train, it was courtesy of British Rail - an organisation hugely derided but one that usually got you to your destination on time and without any thought of mortal danger. Hatfield, Clapham Junction, Ladbroke Grove, Potters Bar, were just uneventful names flashing past your carriage window.
