While I'm going on about this stuff, have you considered becoming a marrow donor? Marrow is also valuable for life and you don't have to be dead to donate. It's a bit more intense than blood donation (much more for proper marrow rather than peripheral stem cells), but you only give once a match is found. Definitely consider it if you haven't before.
And, finally, please register as an organ donor. In some countries, you might be by default, but a lot of countries require you to opt-in. Go check and register if you need to!
A quick PSA:
If you're able to do so, please give blood! Blood supplies are generally lower than demand for blood products, so giving blood can very much save a life. So, please, check the eligibility requirements for your locale and, if you're eligible, go donate! Whole blood, red blood cells, platelets, or plasma, all are useful!
