So five (really) smart people decided that my work was good enough for a PhD... personally, I think I just overwhelmed them with the number of pages they had to read. I kind of screwed up a bit on my presentation (but, oh well, most people there had already heard me talk before and knew what I was doing). The closed door session went surprisingly easy. I did get some tough (or unexpected) questions (like "can you ever prove causation?"), but they tended to be questions that had no correct answer. I'm glad it's all over and thanks to those who attended it (like MadDR2, who is weeks away from his own defense... you'll do great, even if you mess up on your presentation like me, you'll get your PhD).
I get about 10 days off before I start med school (I am doing a 2-week Radiology rotation before med school actually starts since I couldn't fit it in my schedule later).
Anyway, I leave you with this (which, with my newly certified expertise, I can assure you is accurate)
