- "Every patient's story starts the same way, it starts with them being fine, it starts in the before. They cling to this moment, this memory of being fine, this before as though talking about it may somehow bring it back. But what they don't realize is that the fact that they're talking about it to us, their doctors, means there's no going back. By the time they see us they're already in the after. And while every patients story starts the same way how the story ends depends on us, on how well we diagnose and treat, we know the story hinges on us and we all want to be the hero."
