the way i think about it, it would make your whole life different if you could save someone else's life for just a week or so of downtime
having a buddy (and then an uncle) both looking for donors made me realize how much you would help the person and their family if you were ever a match
my dad got called in once and got to the second or third round for someone, but was not a close enough match and wasnt asked to do the actual procedure
every year or so they send you a note thanking you for being on the registry, asking to confirm that you still want on it and confirming all your details
if everyone was on there, it could save a lot of lives...
