Organ Donation

So I was reading this article on Yahoo! Canada about a group of people who were donating kidneys just to do it to help another person. It was very inspiring and amazing to see people do that for someone that they didn't even know. It made me start thinking about if I would do that, and I probably would. I mean, life is the most important thing in the world and saving someone's life is probably one of the best favours one can ever do. Although when I was reading about the donation of a kidney, and I was thinking about that but for some reason I got a serious pain in my side... Perhaps that's a psychologically-caused pain? Hopefully!
