James Harrison (blood donor)

James Harrison is a person who has special blood that can be really helpful to other people who are sick or injured. His blood has something called an antibody in it that can help save lives. So, James Harrison goes to a special place called a blood donation center and gives some of his blood to help people who need it. That's kind of like how you might share your toys with a friend who doesn't have any toys, to make them happy and feel better. James Harrison does this a lot and has helped save many, many lives!
