An Australian man who has been donating his extremely rare kind of blood for 56 years has saved the lives of more than two million babies.
James Harrison has an antibody in his plasma that stops babies dying from Rhesus disease, a form of severe anaemia. He has enabled countless mothers to give birth to healthy babies, including his own daughter, Tracey, who had a healthy son thanks to her father's blood.
Mr. Harrison has been giving blood every few weeks since he was 18 years old and has now racked up a total of 984 donations. When he started donating, his blood was deemed so special that his life was insured for one million Australian dollars.
He was also nicknamed the “man with the golden arm” or the “man in two million”. He said: “I've never thought about stopping. Never.” He made a pledge to be a donor aged 14 after undergoing major chest surgery in which he needed 13 litres of blood. “I was in hospital for three months,” he said. “The blood I received saved my life so I made a pledge to give blood when I was 18.”
Just after he started donating he was found to have the rare and life-saving antibody in his blood. At the time, thousands of babies in Australia were dying each year of Rhesus disease. Other newborns suffered permanent brain damage because of the condition. The disease creates an incompatibility between the mother's blood and her unborn baby's blood. It stems from one having Rh-positive blood and the other Rh-negative.
His blood has since led to the development of a vaccine called Anti-D. After his blood type was discovered, Mr. Harrison volunteered to undergo a series of tests to help develop the Anti-D vaccine. “They insured me for a million dollars so I knew my wife Barbara would be taken care of,” he said. “I wasn't scared. I was glad to help. I had to sign every form going and basically sign my life away.”
Mr. Harrison is Rh-negative and was given injections of Rh-positive blood. It was found his plasma could treat the condition and since then it has been given to hundreds of thousands of women. It has also been given to babies after they are born to stop them developing the disease.
It is estimated he has helped save 2.2 million babies so far. Mr. Harrison is still donating every few weeks now.

Seven Health Facts about Coffee
When you’re considering your morning coffee, here are some health facts to keep in mind:
1. Coffee Reduces Your Risk of Diabetes (糖尿病)
In a 2005 review of nine studies, researchers found that for those that drank four to six cups of coffee per day, versus only two or fewer, their risk for Type 2 diabetes decreased by almost 30 percent. The number decreased by 35 percent when people drank more than six cups per day. And if you’re picturing yourself running around the office with your eyes bugging out of your head, no worries because caffeinated and decaffeinated coffees provided much the same results.
2. Coffee Fights Free Radicals (自由基)
We often forget that coffee is actually a plant and like all plant foods, the coffee bean contains more than 1,000 naturally occurring substances called phytochemicals, which may help prevent disease. Many of these phytochemicals are antioxidants which protect the cells from damage from free radicals.
3. Coffee Improves Memory and Cognition
Researchers reported that volunteers who drank caffeinated coffee in the morning performed better than nondrinkers on tests that involved learning new information. Coffee can also improve cognitive function as we age. One study found that combining coffee with a sweet treat had an even bigger impact.
4. Coffee Can Increase Osteoporosis (骨质疏松)
It’s true that coffee can cause the body to excrete calcium in urine. We don’t want the body to rid itself of calcium because this can lead to osteoporosis. According to The Diet Channel, about five milligrams of calcium is lost per every six ounces of coffee consumed. But these calcium losses can be counter balanced with two tablespoons of milk or yogurt per cup of coffee.
5. Coffee Causes Wrinkles
Even though coffee has antioxidants, if you drink too much of it, it can cause wrinkling of the skin. This is a result of dehydration (脱水) which is the worst thing for your skin. So when you’re drinking that morning cup or two, make sure that you’re pairing it with water. Even better, add one tablespoon of chia seeds to your water and let them sit for 30 minutes. The chia seeds keep you even more hydrated than regular water.
6. Coffee Can Actually Cause Weight Gain
The blood sugar changes that a caffeine high produces can contribute enormously to a strong desire for it, according to iVillage. Coffee is also socially connected to food. For example, we pair coffee with dessert or that morning powdered doughnut. Additionally, when we crash from our caffeine high that’s when we reach for all sorts of fatty snacks to keep us going.
7. Conventional Coffee Is Laden with Pesticides (杀虫剂)
The coffee plant is one of the most heavily sprayed crops. It’s coated with chemicals, pesticides, and herbicides, nothing you’d want to be swallowing. If you do drink coffee, make sure that it’s the organic variety, free from assorted chemicals that leech into our ground water and can make us sick down the road.
If you switch to decaffeinated coffee, make sure the caffeine (咖啡因) is removed in a natural way without the use of chemicals to do it. Often times, conventional decaffeinated coffee has more chemicals than regular.
1. If you want to decrease the risk of diabetes by 35%, you need to take at least _____ cups of coffee every day.
|
A．seven |
B．six |
C．five |
D．four |
2.If you are a heavy drinker of coffee, a far better way to avoid wrinkling of your skin is to drink water _____.
|
A．less than usual |
B．regularly |
C．with sugar |
D．with chia seeds |
3. Which of the following statements is wrong?
|
A．Adding two spoons of milk to a cup of coffee can prevent calcium losses. |
|
B．Decaffeinated coffee has different effects from caffeinated coffee as to diabetes. |
|
C．Many phytochemicals protect the cells from damage from free radicals. |
|
D．The organic variety of coffee plant is free from assorted chemicals. |
4. The author has a/an _____ attitude towards drinking of coffee.
|
A．positive |
B．negative |
