Man Gives 100 Gallons Of Blood In 35 Years
Harold Mendenhall is one unique volunteer: In 35 years, he has given 100 gallons of his blood to help save lives.
He never looks as the needle goes in.
Even though he’s done this more than 400 times, Harold Mendenhall still doesn't like to watch it sliding into the raised vein on the inside of his left arm.
It doesn’t hurt, he just doesn’t like the visual.
