So today it's back to school. I go to work, then make the hour commute out to school, and sit through a three hour class. There's a very real chance I'll fall asleep at some point during the process.
I used to take hour commutes to sit through three hour lectures when I was in graduate school. It does tend to be a good practice in figuring out exactly when is a good time to sleep, as you don't want to miss your stop and you don't want the professor to catch you sleeping.
