That's a terrible idea. From a Reddit thread: >I have a friend who is a doctor. I have another friend trying to donate a kidney to a stranger. My doctor friend said that's a terrible idea for you personally because doctors have a phrase "nobody should die with 2 kidneys." What it means is that a lot of extreme medicines they might try if you're really in trouble have a high risk to kidneys. In other words, you need a buffer kidney in case of a need for risky medication, as that is very common. Just my personal experience.
