I put myself down as a potential bone marrow donor. I met the criteria, they took mouth swabs, and was asked to sign a form that I would try to be avialable if the need arose. I'm pretty confident of my ability to actually go through with it, should I be called. I'm not the bravest animal in the shed, but feel ok with this, and don't judge others who, for whatever reason, would not do something like this. For example, I don't think I'd voluntarily donate my kidney to a stranger, and yet people do. What do you think? Any of you go beyond giving blood?
