Awe

I just don't understand why we need an entire book to tell us about our own personal reason for experiencing awe. I felt as if most of the first half of the book was dedicated to tales about what caused others to experience awe. But seriously, when he stated that he experienced awe after crying over a song that made him sad, that just made me shake my head. And that seemed to make him more sad than the entire tale he told of his brother taking pills to end his life (was it assisted suicide?).
Some parts were too technical, with references to things I didn't know, but the author believes we already know. He may be an expert in his field, but not in writing a book.
Again, I just don't understand why we need an entire book to explain what makes us go Awe! I would think most people already know.
