I photocopied an article on laboratory automation for me to read during an upcoming flight. I sure hope that I do indeed get to read this. I might get sucked into a game of Sudoku. It's mentally stimulating, but not a good use of my time. It'd take way too long to get better at this game, and I don't think that would be an efficient use of my limited time.
Besides, I'd rather be working out. Tried to make it through a grueling hour-long intensive cardio workout, but I had to quit halfway through. This darned cold that I'm recovering from has just sapped my energy levels. Darn it.
