My wife uses this for quick & easy relief from discomforts that crop up. She says, 'simple is better' when showing others how to help themselves especially when they know little to nothing about the the body's energy systems. She's given some of the specific exercises in the book to several young mothers with grade school children who experience behavior problems, who say their children love doing these or having their mother help them perform the exercise. Best of all they say their children are doing much better. Who knew!
