My sophomore year of college I took a 200-level biology class about exercise. I had to take several natural science classes to fulfill my general education requirement, even though I wanted to do nothing but hang out in the theater building. I hoped that because the class was about exercise, I would find it interesting.
I didn’t.
The professor of this class spent each session lecturing to about 100 college students on biological systems and processes that were only relevant to exercise in the way that all of biology is relevant to, well, something.
