I wonder if human beings can and do pick up radio signals. Sounds crazy, I know. And maybe it is. But I remember as a child that there was an old Pye record player in the house which was capable of recording onto an LP size brown disc. And if we put our fingers on the "recording" needle when it was slotted onto the playing arm we could hear radio signals. I'd love to say that by moving our arms around we could tune to different stations. But that would not be true. The only time the record player put out radio programmes was when a human being put their finger on that needle. Now perhaps there was some weird freaky set-up inside the gubbins of the Pye that meant it could function as a radio, of which even the manufacturers were unaware, and us kids were simply acting as an antenna. I've often wondered what it was all about.
