"I have this person whom I love very much, and he needs a healthy kidney, and I have two of them. So of course I'll give him one."

How would you define an act of love? What about donating a kidney to a person you deeply care about, one who is a dialysis patient? I believe this is one of the great acts of human kindness, one that brings empathy to a whole new level. Our guest today, Dr. Vanessa Grubbs, MD, a nephrologist, gave her heart and a kidney to her boyfriend, Robert, who is now her husband. It’s all documented in her very candid book, Hundreds of Interlaced Fingers, which is a love story, yes, but one with very useful information about kidneys and kidney disease, too.
