What Is This Hobby?

I frequently see in this forum references to "this hobby" and I'm always a little confused by the phrase. What exactly is this hobby?

I was obsessed with critical listening. Now I realize that was foolish. Imagine a plane that overshoots the runway by 10 miles. I should have stopped a long time ago and listened exclusively to the music.
