This US Man Has Donated Over 110 Litres Blood, Calls It "Multitasking"

Until the previous five or ten years, he donated every 56 days. However, with age he tries to "stretch it out a little bit."

A man from Long Island in the United States has donated around 29 gallons of blood (approximately 110 litres) in 49 years. Henry Bickoff, aged 68, started the noble deed in 1975. His blood has helped 693 people, according to the New York Blood Center.

He has donated the equivalent of 870 single-serve ice cream scoops, 310 Coke cans or almost six-gallon office water cooler bottles. "I've been doing it for a while," he told the New York Post. "It's something I've committed to, and it's actually nice to get a little bit of recognition for it," he added.

The eye care professional made his first donation when he was in college. "Everybody was doing it. It was a save-the-world kind of situation of do something good for everybody," Mr Bickoff said. However, he recalled his first experience and said that he was "very dizzy" after the donation since he was not hydrated, fed or rested. However, it did not stop him from continuing to do it.
