I had biology the first thing in the morning, and I wasn't a morning person. There's nothing like a good whiff of formaldehyde to start the day.
When I was returning to school, I was considering a career related to the health field and took a biology class to fulfill some requirements. In a smaller room from our lab was a woman's body zipped up in a bag - it had been donated some years ago to the school for educational purposes. When the instructor told the nursing students she was in there, they all excitedly headed in the room to take a look. It creep me right out.
I recently graduated for accounting.
My zoology class was right before lunch. I was on a formaldehyde induced diet through those credits :P
