Please consider registering as a bone marrow donor.
This is something I've been thinking about for a long time, more so lately. I used to donate blood regularly—every eight weeks, like clockwork. My blood is type O negative, which means that it can be given to anyone regardless of their blood type with minimal chance of complications (which is why in shows like ER you hear phrases like "push 2 units of O neg") and CMV negative, which means that it can be given to infants and pregnant women without concerns about them contracting, well, a cytomegalovirus infection. Check the link above for more information; all I know for sure is that it means I get called by the community blood center a lot.
Unfortunately, the last few years I've been busy with work, and usually feeling less healthy than I should (largely, I suppose, because I sit at my desk all day instead of exercising), the upshot being that I donate very, very rarely anymore. I reached my first gallon before I started college, my second some years ago, and am probably nowhere near a third.
That will change.
