I wish I would have learned biology or health with this book in high school. It makes the body so easy to understand. It reads as more of a reference book and I'll keep it around as such. For example, I had a sore throat recently and I remembered trying a salt water gargle in the past with little success. I looked it up in the book and I realized the only quick fix to feel better was a salt water gargle with warm water a certain number of times a day. It worked!
It's also made me stick with taking a multi-vitamin every day and with the back-up of my own Dr. of course adding 1200 mg of calcium + Vit D (which I didn't think I needed at my age).
