Natural born heroes

The blend of history and adventure in this book is fascinating. I'm curious what motivated the author to focus on these lost secrets and how he uncovered them.

The book jumps between different eras and anecdotes, which kept me engaged but also made me wonder if this approach might be confusing for some readers.

There are so many remarkable stories, and I wonder how the author chose which ones to include and which to leave out—what was the selection process like?
