So I've never read about bone marrow donation, but I had never imagined it required being put under general for. Erk. o.O (I've been under general for surgery, and I suspect the fasting before hurt me more than the anaesthesia itself.)

Meh. I'm O- and have never donated blood; I make the excuse that I don't meet the weight requirements, but honestly, my veins go flat and hurt so quickly during routine small medical draws, that I can't imagine going through a blood donation draw without a LOT of pain, so I'm not willing to skirt the weight rules and try anyway.
