As long as you help another victim with a kindness, you are a hero. For example, every time you donate blood, you are actually saving the stranger you don't know. You are a veritable hero.

There is a person in the world who has done the ordinary act of donating blood to the extreme. This is james harrison. He is an ordinary man without any fame.

In 60 years, he donated blood 1 173 times, and his blood saved more than 2.4 million lives. He holds the world record for the number of blood donors. What was his old age like? Do you live a long and healthy life?

He can prove to us whether it is good or bad to insist on donating blood for a long time.

Harrison can always donate blood so frequently because people need his blood. His blood is special.

Harrison has a special and rare antibody in his blood, called anti-D (also called Rho(D) immunoglobulin), which makes his blood comparable to gold.

We know that human blood types are generally divided into A.B.O But there is also a blood type system called rhesus monkey blood type system (RH), which can be divided into yin and yang.

If a mother's blood type is RH negative (RH-) and her partner is RH positive (RH+), they will produce RH positive antibodies in the mother after giving birth to their first child.

When they want to have another child, the child will still inherit the father's RH positive blood type, but at this time, the RH positive antibody produced by the mother will attack the child's blood cells, leading to hemolysis, that is, rhesus monkey disease.

This situation can lead to serious brain damage and even death.

Harrison's blood is specially lost to such mothers, so that they can continue to give birth to healthy babies.

Harrison and two healthy twin babies, thousands of babies in Australia owe their health to Harrison's contribution.

Because the anti-D in Harrison can resist the attack of RH positive antibody and protect the baby from harm. However, Harrison's blood alone is difficult to meet a large number of needs.

So the researchers used Harrison's blood to make a vaccine, as long as the mother with this problem was vaccinated before the second pregnancy.

The main ingredients of the vaccine still come from substances in Harrison's blood, so Harrison will still donate blood regularly.

So how did Harrison have this super power?

Harrison didn't have this antibody in his blood when he was a child. It was an accident that caused his blood to change when he was 14 years old.

At this time, young Harrison knew that he could survive because he had donated the blood of other good people, so he decided to donate blood to save other people's lives as long as he recovered and was still alive.

It is this belief that sustains Harrison's life. But Harrison was only 14 years old, and only 18 years old was allowed to donate blood.

Harrison's blood donation record ranges from 1967 to 1969.

/kloc-at the age of 0/8, Harrison began to insist on donating blood once a week. This frequency can be said to be close to the limit, and too much will do harm to people's health.

Because it takes about 7 to 10 days for the human body to make 500 ml of blood. In the initial blood donation, the doctor analyzed his blood and found a rare anti-D.

From 65438 to 0966, Harrison was invited to participate in the experiment of a new anti-D vaccine. In the same year, the vaccine against rhesus monkey disease was successfully developed.

Since 1955, he has been insisting on donating blood because Harrison knows that he can save children. From 1955 to 20 173 times, he donated blood 1 173 times, saving more than 2.4 million children suffering from rhesus monkey disease in the process.

Every dose of anti-D vaccine produced in Australia comes from Harrison's blood.

Maintains the world record for the largest number of blood donors.

This is the last time that james harrison donated blood to the Australian Red Cross.

Harrison, 8 1 year-old, stopped donating blood because health is the most important age for him. He was awarded the world record of the person who donated the most blood by Guinness World Records.

During his life, he received thousands of letters and gifts to thank the children he saved by donating blood. People even want to meet him and thank him in person.

On May 18, 1 1, james harrison made his173rd blood donation, which was his last one.

Now james harrison is still alive. He is 84 years old. Health and longevity.
