Because of your thoughts and comments, I have had the serendipitous brainwave for how to focus my vast and currently unfocused glut of material for this final essay. It's a direction I hadn't even thought about, frankly, because I viewed the PK material as pretty tangential to my mission here--at best, a standalone piece.
I'm really psyched about this, thanks so much! That's the good news. The bad news is that I may ask follow-up questions to get angles and details I hadn't considered. I hope that's okay.
