This is a great book to learn some of the deeper points of anatomy and health, without getting excessively technical. For instance, have you ever wondered why do people get less colds as they get older? This book says it is because each time you get a cold, you get an immunity to that virus, but because there are so many viruses, we never get an immunity to them all. This and other interesting things are in this book. By the way, this book is written mostly on a high school or adult level.
Science was not one of my favorite subjects, as a child. I found this book while homeschooling my boys. I enjoyed it so much that I kept it on my bookshelf. It points to the Creator. When you read it you wonder, "How can anyone not believe in the existence of God? "
