Over the last year, we've talked about the importance of joining the National Marrow Donor Program. It's literally just a few minutes of your time and there are so many people who are terrified and battling a very sinister disease in need of transplant. You could be their match. Getting registered is painless and from now until May 19 it's free for non-minority registrants. Please take a moment and visit this site: http://www.donorgarden.org/main/default.aspx
If you're called up to donate, it's virtually painless and will probably only take up a day of your time. That's not a lot to ask when you consider that you'll be providing many "tomorrows" for someone like me.
If you're already registered, don't forget to keep your profile updated with the NMDP. They need your current information, like how to contact you in case you're needed.
It'll only take you the time to do a cheek swab and post the kit, so what are you waiting for?
