What's Your Favorite Question to Ask?

I wanted to act like I was kind of ghostwriting each chapter, but ultimately I ended up just by virtue of an act. The more I think about it, the more it confuses me. There's a kind of mystifying fact that no matter how large animals can get, they used to be supposedly much larger when there was less oxygen. Is there is there a physical limit to the size of a single conscious self? And then you can ask how small you get.
