In Australia, Joe Mannana plans to make a trip to donate his blood.

What is so interesting about this man?

First, he is 79-year-old.

Second, he has donated his blood over 1000 times during 36 years.

Last, he has saved over 20,000 lives of infants and mothers.

Born with RH- A blood type that can also be replaced with RH+ A blood type, he indeed is a rare man with mutant but precious blood.

He began this donation marathon after he survived a difficult surgery that demanded a special blood like his. However, the doctors later realized that the operation proceeded successfully even after wrong type of blood had been transfused into his body. Since then, he decided to save other lives and contribute to the medical experiments.

Even though he has already been marked as a significant benefactor of the medical field, he continues to incessantly donate every possible drop of his blood.
