I consulted my to read list and saw that "Guns, Germs and Steel" was first on the list of his books to read.
I've been so busy writing that I scarcely have time to read. Am readying a new book (How I became a healer - memoir) for copyright.
And working on a 9 book series - grappling with questions of how to resolve intractable conflicts without violence and whose main theme is anchoring humanity to the Oneness Principle through dramatic fiction(science-fiction/fantasy).
I turned 70 this year so who knows how much time I have left.
