Not only do I get to feel good about the fact I am currently only a third of a percent of those eligible in England (yes that means only 3 in 1000 are registered as bone marrow donors) I also get a funky blue card to carry around with me. Watch out people of Wolves, I intend to flash it whenever possible and hopefully get a few more joining in.
18 to 40? painless to register, just a quick swab inside the cheek.
