Natural Healing is a subject very dear to me, so of course I've devoured many books on the subject, but am very willing to keep getting the same material from different sources in hopes that I will eventually get it and shift my lifestyle to more healthy directions.
The first lecture, I think Dr. Guarneri was establishing her credentials (which are more excellent than all my other sources) and summarizing what the course is about. I was anxious to get to the "meat" so was frustrated that she wasn't getting right to it. Still, I'm glad she started out explaining her own history. Also, in the first lecture (only about 30 min each) she seemed to pause a lot at the end of a statement. That drove me nuts and I vowed to set the speed on my iPod up a notch when I transferred the lectures to it. However, by the time I was listening to the 2nd lecture, either she wasn't doing that as much, or I had gotten used to it, so I never changed the speed. I think it helps me to absorb what is being said better anyway.
For the first third or half of the lectures, I was hearing mostly familiar things but in a way that was more helpful than before; but in later lectures, I'm hearing things I didn't know, so this has proved much better than I expected. She has also provided many things I can research and follow up on, and things I'm anxious to try out. I'm only about 3/4 of the way through this course but it keeps getting better and better.
