Yes. When my nephew was born he was very sick and needed blood that was cytomegalovirus negative, which is extremely rare. Our family had a huge "private" blood drive at the Red Cross, and I was a match. But everyone won that day - there was something like 300 people showed up to give blood trying to find a match, so many lives were surely helped by it.
Well, I wouldnt mind cooking on holidays if my mother wasn't such a witch with a capital B. She kind of ruined holidays for me a couple of years ago, they haven't been the same since. I like cooking on regular days, though, if someone's around to appreciate it.
What would you do if a family member needed a kidney and you were a match?
