And if we move back again, here, and we put on trails on them, like this,
我們再回到過去，給每個球畫出運動的軌跡，
you can see again that the speed of development is very, very different,
可以看到，發展速度的差距非常大，
and the countries are moving more or less in the same rate as money and health,
雖然各國的經濟和健康發展的軌跡大同小異，
but it seems you can move much faster if you are healthy first than if you are wealthy first.
但是健康水平起點較高的國家，發展速度遠超過經濟水平起點高的。
And to show that, you can put on the way of United Arab Emirates.
為了說明這一點，我們看看阿聯酋。
They came from here, a mineral country.
他們從這里出發，一個資源型國家。
They cached all the oil; they got all the money; but health cannot be bought at the supermarket.
他們靠石油大把賺錢，但健康絕不是超市里的貨物。
You have to invest in health. You have to get kids into schooling. You have to train health staff.
你需要衛生方面的投資。需要提高兒童的教育水平。需要培訓衛生工作者。
You have to educate the population. And Sheikh Zayed did that in a fairly good way.
還要教育民眾。Sheikh Sayed干的非常漂亮。
In spite of falling oil prices, he brought this country up here.
盡管油價下跌了，他仍改善了阿聯酋的健康。
So we've got a much more mainstream appearance of the world,
這里我們可以看到世界發展的主流，
where all countries tend to use their money better than they used in the past.
各國對資金的分配和使用都比過去合理的多。
Now, this is, more or less, if you look at the average data of the countries -- they are like this.
這里大家看到各國的數據基本上都是平均數。
Now that's dangerous, to use average data, because there is such a lot of difference within countries.
但是用平均數可能會很危險，因為國家內部也存在很大的差異。
So if I go and look here, we can see that Uganda today is where South Korea was in 1960.
我們看這里，今天的烏干達和1960年的韓國差不多。
If I split Uganda, there's quite a difference within Uganda. These are the quintiles of Uganda.
如果把烏干達分解開，可以看到內部的明顯差異。
The richest 20 percent of Ugandans are there. The poorest are down there.
烏干達最富有的20%在右邊，最貧窮的在左下邊。
If I split South Africa, it's like this.
如果把南非分解開。
And if I go down and look at Niger, where there was such a terrible famine, lastly, it's like this.
尼日爾在下邊，他們剛遭受一場恐怖的饑荒。
The 20 percent poorest of Niger is out here, and the 20 percent richest of South Africa is there,
最貧窮的20%的尼日爾人在最左邊，而最富有的20%的南非人在最右邊，
and yet we tend to discuss on what solutions there should be in Africa.
今天我們仍然在討論什么方案能解決非洲的問題。
Everything in this world exists in Africa.
世界上所有的問題非洲都有。
And you can't discuss universal access to HIV for that quintile up here with the same strategy as down here.
我們不可能討論出一套通用方案，既能解決這些地方的艾滋病問題，同時也適用于這些地方。
The improvement of the world must be highly contextualized, and it's not relevant to have it on regional level.
世界的發展一定要因地制宜來分析，僅從各大洲的水平上來分析是不夠的。
We must be much more detailed. We find that students get very excited when they can use this.
我們必須更加詳細。當學生們接觸到這個軟件的時候，他們都非常興奮。
