In 1996, Rosa saw a video of Therapeutic Touch (TT) practitioners claiming they could feel a "Human Energy Field" (HEF) emanating from a human body and could use their hands to manipulate the HEF in order to diagnose and treat disease. She heard Dolores Krieger, the co-inventor of Therapeutic Touch, claim that everyone had the ability to feel the HEF, and Rosa heard other nurses say the HEF felt to them "warm as Jell-O" and "tactile as taffy." Rosa was impressed by how certain these nurses were about their abilities. She said, "I wanted to see if they really could feel something."
