Reusing content from former book:
I decided to write a book about the effects of martial arts on health and longevity. I need to explain the origin and purpose of earlier history and practice of the Shaolin temple. Would it be in bad taste to reuse a portion of my first book to explain these in the second book. I plan on adding extra content along with this to get my point accross. It would only be using a few paragraphs in a couple of places where needed.
