Last september, cnn s last remaining original employee, senior u.n. correspondent, richard roth, sent a letter to his co workers. he was in desperate need on of a new kidney. he said even though he received one 25 years ago, it was now dieing inside of him. that s when his colleague samira gentleman farry answered the call. they started intense testing around thanksgiving to see if she was a match. richard successfully received a kidney from the woman who he now calls his heroine. i want to ask you both the same question. richard, starting with you.
