A friend used to say that my most treasured possession was a letter (not an email, a signed letter) from one of the great biologists of the 20th Century, John Maynard Smith, declining a conference invitation (very politely). I’ve since lost that letter when changing countries, upgrading my Luke Skywalker in Hoth action figure to the #1 place.
