How often do you donate blood? Once a year? Once every few years? Never? Would you be willing to do it every few weeks? That is what James Harrison of Australia has been doing for almost 60 years. In that time he has donated blood over 1,000 times.
James Harrison has very special blood—so special he has been called the man with the golden arm. When James was a teenager it was discovered that his blood contained a rare antibody. After it was detected James volunteered to help scientists create the Anti-D vaccine, which required the antibody in his blood.
