> Turns out people don't know their actual physical addresses either any more. Just move countries and cities often enough, and throw some business travel in for good measure, and it's pretty easy for that to happen. I've e.g. had similar sounding zip codes in a variety of cities and countries, and nearly the same street name within a city. After a while you start to very easily make mistakes.
