Shelly Hughes says three things are required to do her job: a strong back, a strong stomach and a big heart.
She's a certified nurse's aide at a nursing home in Washington state, which also means another requirement: To get her work done, she has to physically be there.
"You're helping residents that may not be able to dress themselves, feed themselves, toilet themselves," Hughes says. "The great stuff is that you get to know wonderful people. I have so many grandmas and grandpas now, let me tell you."
