"Nurses are angels in comfortable shoes."

They're the 'heart' of our healthcare system - the glue that holds everything together. Nurses save lives. Nurses protect lives. Nurses make lives easier, for both patients and their families.

There are more than 2.5 million Registered Nurses in the United States and hundreds of thousand more in Canada. In A Work of the Heart you'll hear from a number of them about what it's like to be a nurse - the joy, the grief, the chance to see life and death play out every day before your very eyes.

You'll also hear why these nurses are so passionate about the importance of good nutrition - and about Juice Plus+. They believe in what Florence Nightingale, the founder of modern nursing, once advised her fellow nurses: "Never lose an opportunity of urging a practical beginning, however small."
