waiting for lungs, 72 children. sara is one of those. 880 children are waiting for a kidney. and 478 children are awaiting a liver. and when you look at adults, and let's again focus on lungs here, 1,614 adults are waiting for a lung. and, again, 72 children are waiting for a lung. if you look at all of this in the big picture, more than 118,000 americans are waiting for an organ. and many of them will die without it. many of them do die without that organ. >> that's why lung donors are so important. >> so important to sign that organ donor card and give your organs if, you know, god forbid in a car accident or something, sign that card so your organs can be useful to someone like sara. >> just a point in case here, i really wish her -- i hope it goes well for that family. but it's very brave of her mother to bring it to the country's attention, really. >> and i think it shows you what happens when you become sort of an active and powered patient.
