Put me under!

Following is a transcript of a recent text message exchange with Mama Bird:

MB: I want to sign up to be a bone marrow donor, but I can’t because I don’t weigh enough.  You want me to sign you up?

Me: What does it involve?

MB: Nothing unless you’re a match, then just blood and marrow cells, all outpatient.

Me: How do they get the marrow cells?  Painfull?

MB: It says a needle in your pelvis.  It says 1 out of every 200 will actually donate and it requires 30 to 40 hours of your time if you are a match.  And you will be sent a packet to provide a cheek swab.

Me: Will an anesthesiologist be present?
