Good news - part 2
In 2008, a Canadian student named Christopher Charles was working in rural Cambodia. He was living in a typical Cambodian house - a house up on stilts to deal with the rainy season. He had no electricity or running water, but lots time to sit around and think.
He started thinking about anemia.
Anemia is often caused by an iron deficiency. It makes you tired and weak. It makes you have trouble thinking clearly. Almost half of Cambodia's population suffers from this disease! In fact, over 3.5 billion people on our planet have anemia, and the World Bank estimates that it's a $50 billion drain on the global GDP.
You can cure anemia with iron supplements - but they taste bad, and they often cause stomach pains, constipation, and even more disgusting problems.
So Charles had another idea: give villagers little blocks of iron to drop into their cooking pots. The iron gets released slowly as the water boils.
But at first, people hated them. They thought the iron blocks where ugly. They thought the iron blocks would scratch their pots. So they turned them into doorstops.
He kept trying. Eventually he came up with a second idea, that could make the first idea work.
He realized that in rural Cambodia almost everything revolves around fish. People earn money fishing, they're a big part of the Khmer diet and their folklore. Even their currency — the riel — is named after a fish!
So, he made iron into "lucky fish" , shown here. And people are now happy to put one into the pot when cooking.
One of those who has been using the fish is Sot Mot, a 60-year-old grandmother who lives just outside Phnom Penh. She drops the fish into boiling water as she chops up garlic, ginger and lemongrass for Khmer chicken soup. "Before, I felt tired and lazy and my chest shook when I was tired," she says. "But after I use the fish, I have strength and energy to work and I sleep well, too."
One of her grand-daughters seems to be improving, too.
"Before, when I went to school I felt tired, and I didn't do well at math, maybe the sixth in the class," says 15-year-old Danai. "Now," she says proudly, "I'm No. 1."
Of course, this idea needs to be tested with scientific studies. And here's one such study:

, Iron-deficiency anaemia in rural Cambodia: community trial of a novel iron supplementation technique, http://eurpub.oxfordjournals.org/content/21/1/43
More studies are coming up.
No matter what the result finally is, it shows that paying attention to local culture can work wonders when trying to help people.
Large parts of this story are paraphrased from the following radio show, which is definitely worth listening to:
