Is it just me, or do other people get really hungry during lectures?

Lectures have the opposite effect on me. But that could be because I had AP biology right after lunch everyday. While I loved that class, the lectures (which happened everyday) usually made me completely un-hungry. It's very possible that it's because we would focus on humans and animals in biology so when we got to anatomy I lost my stomach. (Seriously, though, if you had seen my teacher, you'd understand why you lose your appetite when talking about human anatomy. Talk about awkward!)
