Query: Very Dated

I'm only about half way though, but not currently impressed. As mentioned, there are some good relaxation techniques, however, the diet portion is basically eat lots of protein to sustain energy and maintain blood sugar levels, the exercises are nill to none for anyone whose not completely sedentary, and much of the hospital info is very dated. In short, it didn't do much for me.
