When a kid, so my mother tells me, I was always taking things to pieces to see how they worked. First my toys then household implements then the gramophone, wireless, my father's tape recorder. I inherited this, I think, from my father who spent endless hours under the hood of his car. I remember being amazed how different things looked inside from out. It only stands to reason therefore that there would come a time when I yearned to look inside myself and see how that worked.
