I signed up to be a bone marrow donor. I was motivated by the TV show House. You have a 1 in 12 chance of being picked; they give you anesthesia during the donation, and NY State employees get up to 7 days of paid leave. I'm a city employee, sadly, but maybe I will get something, and even if I don't, I'm in it for the good karma.
In other news, The Bahamas sent me a birthday email and urged me to return and visit. I think this is genius-- they got my birthday off their immigration forms.
