This was a doodle that I had done for a buddy of mine that sat next to me in my anatomy and physiology class. We were being lectured on rabies, and there were some classmates that had then paralleled the disease with zombification. I then turned over aforementioned buddy's cardiac worksheet and asked him if I could doodle on it. This was what happened.
"Anatomy for the Artist" is the title of a European book that I had studied independently in order to properly grasp the mechanics and form of the human body. I had recommended it to him, as he was a fellow aspiring artist.
"Don't Do Drugs" was just a little note due to the fact that the doodle had reminded me of an addict.
