I am very impressed by this little book. You can find out just about everything in this book. The medical information contained in this book was superb. I am reading it little by little every night and I also use it as a quick reference for when I need to find a little something about someone’s medical condition. Because the book is so useful, I usually keep it with me at all times and since it’s a paperback it’s getting beat up. I’ll have to buy a hard-cover soon.
