content: I use this book because I am under a doctor's care and have to track my food intake and exercise daily. I'm also supposed to take notes on how I feel physically each day. I was happy to find a book that included everything I needed. It's the first one I've found and I've been doing this for a while. I also write my medications down on the journal page after I take them and have them all listed in the front. That way in case of emergency the crew would know what I take. I carry this book in my purse and love it.
