a LITTLE more than useless

as of today i am a ....bone marrow donor!
we had a blood drive at school, i'm not allowed to give blood because of the random assortment of diseases i have had in the past 5 years but i was able to join the marrow donor registry...and so I did!
so, if this life comes to not saving any people at all( if all else fails and I do not become a nurse) hopefully I can be the one to save someone's life through my marrow.
most people aren't so excited about something like this.
but the cotton swab thing I got to do to test my HLA(whatever that means) got me a little more excited.
so this body may be worthless and 30 years old(says the doctors-internally) but i still have valuable bone marrow!
sooo world...TAKE THAT!
a little more than useless,eh?
