The young man from the previous post just recounted a recent conversation he'd had. He was talking to a college student who is thinking about applying to med school, and asked him what kind of doctor he wanted to be.
The student jokingly said he wanted to be a gynecologist.
The young man then told him, "Listen, the unicorn is a magical animal. But if you had to spend your entire day shoveling unicorn shit, would you still find them as enchanting? And do you really want to live in a world where unicorns have completely lost their appeal?"
