I did always love biology, not because of my teachers, but because of my own wonder of it ("I sort of get how an engine works, but how do humans work?"). And I became a biologist, and thinking about the things this author describes indeed still blows my mind. I get the high level of a lot of things now, but every time I need to do a deep dive, I feel like "how the hell can this even work". But it works, and it works incredibly well. I still think it's the nicest field to be in (even though I love computers and Linux and FOSS as well).
