A 73-year-old man from Port St. Lucie, Florida, has saved the lives of 864 people by donating blood for decades. Since 1976, James Michelini has donated blood and platelets every second Wednesday. After 43 years, he has made his initial target of 10 gallons ten times for a total of 100 gallons. Every pint of donated platelets can save the life of one person, while every pint of blood has the possibility of saving up to three people. So that amounts to 864 lives saved with the 100 gallons Michelini donated
