(Off topic anecdote)

A friend of mine has a father who had a file on him by the Stasi. In it they had a "scent sample". Someone had broken into his bedroom and stolen a piece of linen that he had slept on while he was in the shower one day. It's crazy to think that someone had/has the job of collecting "scent samples". And what a government would need that for, really.
