I've been on the Organ Donor Registry for about 30 years. I signed up before most states gave you that option on your driver's license. It was a no brainer as they say, and what could it hurt? I would be dead by the time they came to collect.
I've often thought about being a living donor. I donated blood for years before a doctor diagnosed me with Lyme's Disease and said I shouldn't donate any more. Although recently, another doctor tested me for Lyme's and I came back clean. So I will probably start donating blood again, once I get off the meds for the auto-immune issue I developed because of the statins I was on.
Anyway, back to being a living donor. Donating blood isn't that hard. I've wondered though, do I have what it takes to donate part of my liver? A kidney? Bone marrow? That involves more commitment, more pain, and more risk. I think I might sign up to be a bone marrow donor, once I have a clean bill of health. My thought is, what's a little pain or risk, if it means you could save a life?
