Saving Lives

Cojo says that physically, a kidney transplant is much easier on the recipient than the donor. "It's a very complicated operation to take a kidney out. It's very easy to put a kidney in. That's why [organ donation is] such the ultimate compassionate brave act."

"How did you feel after you had done it?" Oprah asks Abby. "Did you feel your friend was worth it?"

"I would do it again in a heartbeat," Abby says.

As a token of his gratitude, Cojo gave Abby a beautiful heart-shaped diamond ring. "I think the only way to thank her," Cojo says, "is to give her my heart and tell her she'll always be in my heart. We have this incredible connection. She's my life."
