The poster of Japanese characters

The reason I'm linking to this is that I've always remembered Ferriss talking about finding this poster of Japanese characters.  I thought it was 1000 characters, but it is actually 1900 plus characters.  The story goes, that he was incredibly relieved to see the finite quantity of actual characters to learn.  (1900!!! interesting take away, Ferriss "what? is that hard?)
But it occurs to me that Immunology can be seen as a language.  All I need to do is learn the vocabulary.  It will be grunt work, but it can't be more than 1900 japanese characters.
