I gave a kidney up for a stranger I heard about on Facebook (who's now a friend) to another stranger I will never meet, and it was pretty neat.

“The main reason I passed that little kidney on for someone else was that I believe I'm worthy of the same gift. That if I needed a transplant I would hope a stranger would step up for me and I know I'm worth that gift. Therefore I had to do it for someone else, because no one should die when someone can save them. Be the person you want others to be for you. So that's what I want to say.”

And she is so passionate about her decision that she literally wears her kidney on her sleeve. (Ashley donated through the paired exchange program). Learn more about it at https://blood.ca/en/organs-issues/living-donation/kidney-paired-donation-program
