James Harrison, an Australian man whose blood contains a rare antibody that can create a treatment that saves babies' lives, has donated plasma one last time.
Harrison, 81, is now over the age limit for donors — in fact, he hit the cap months ago.
But the Australian Red Cross Blood Service let him donate one last time on Friday. The service estimates that over the course of his life, he has helped save some 2.4 million babies.
Harrison, known as "the man with a golden arm," has donated blood and plasma regularly for more than six decades, from age 18 to age 81. All told, he donated 1,172 times — 1,162 from his right arm, 10 from his left, the Sydney Morning Herald reports.
"I hope it's a record that somebody breaks," Harrison told the Blood Service.
