My brain is a wet noodle

I have just finished 5 hours of homework.  Add that to the 7 hours that I'm in class each day, with short breaks to eat, ride the bus with smelly people, and go to the bathroom, you have the majority of my day.  Don't get me wrong, I love learning and school (heck, I'm a teacher) but I feel like these past few weeks have caused me to delve into the little used recesses of my brain and give them a poke with a cattle prod.  All of those calculus and math indents in my brain tissue have lain undisturbed for 12 years, only to be rudely awakened by statistic formulas.  "Help!" they scream, "We thought that we were in our retirement years, sipping virgin pina coladas on the beach."  Oh no, now they are forced to work again like septuagenarians at Walmart.  Argh.
