HARTFORD, CT (WFSB) - Recent studies show that more than 50 percent of female nurses in the United States are obese. However, a Connecticut hospital is taking charge and making a big change among the nursing staff. Last June, St. Francis Hospital nurses Crystal Miller and Kelly Chevalier embarked on a special journey together to better their health. “I was pretty fat,” Chevalier said. “I don't know what I saw when I looked in the mirror, but I didn't like it,” Miller said.
