Reading your post @nanohousehold, I am reminded of another book I recently read that I highly recommend, Victor Frankl's "Man's search for meaning". I found this to be a very captivating book. It was hard to put down.
Re: "Heavy metal", I've been a punk/metal lover for most of my life, so I will give "Hidden Nature" a go!
@madbitcoins once again, THANK you for this post, I love reading books!!!
Thanks for the reply and the recommendation.
Just for the record, Hidden Nature is by Alick Bartolomew.
Its contents are mainly about water and energy, not about heavy metal.
I see, heavy metal is just a part in the book, thanks for the clarification!
