The Final Countdown

I have that great '80s song, The Final Countdown in my head as the week progresses toward submission day (June 12), graduation day (June 15) and defense day (June 23). I am concerned that I have not heard from my chair about two of my chapters. But he'll pull through at the end and I'll be left scrambling to revise in time. As long as everything is signed off and submitted by the move, I'm fine. Until then...
