Well, I've just learned that I am officially banned, for life, from donating blood. Why? Because I have bovine material swimming around inside of me. You may recall that when I had my spinal fusion surgery back in December 2007, the surgeon used cadaver bone, bovine material, and even some synthetic material.
I was hoping to donate as part of my synagogue's big Mitzvah Sunday event - the whole community was coming together to do all kinds of mitzvot (good deeds) to help the temple and the world around us. One of the ways that I was looking forward to participating was to be a good role model by donating blood.
I now learn that those of us lucky enough to have cow parts are not allowed, permanently, to donate blood.
However, when I kvetched about this to my sister, she wisely answered, "Well, which would you rather have? The ability to donate blood, but be in pain? Or your life back and be totally healed?"
Well, when you put it that way.... :)
