Ray,
It keeps getting better. I still really like the font. I can't really decide which color works better. Please keep massaging that icon if you can. I like the book as a graphic device. However, the heart-monitor line may be too subtle. My wife, who works in health care, did not grasp it at first. For some ideas, check out this URL;

Good luck.
