Two coworkers confided in each other about their husbands' illness. Then both donated a kidney to the other's husband.

Last year, two women were chatting in the bathroom at work and both discovered their coworker could help save their husband's life. 

Tia Wimbush and Susan Ellis worked at Children's Healthcare of Atlanta for over a decade and were in the same department for five years. A mutual friend had told them they had something in common — Wimbush's husband, Rodney, and Ellis' husband, Lance, were experiencing kidney failure.  They confided in each other about their husbands' kidney disease, a condition that affects an estimated 37 million people in the U.S., according to the National Kidney Foundation.
