If more people donated organs after their death, it would not be necessary to use live donors.

如果更多人捐赠器官后死亡，就没有必要使用活的捐助者。

About a third of all donated organs are harvested from live donors. Nearly all the rest come from people who have been declared brain dead while undergoing treatment in hospitals.

大约三分之一的器官捐献都是来自活体捐献者，剩下的则基本上来自那些已被宣布脑死亡而又在医院接受治疗的人。

They could, for instance, receive health insurance as part of their payment—which would be cheap because properly screened donors appear to live longer than the average Joe with two kidneys.

比如，他们可以获得健康保险作为报酬的一部分——这笔费用可能要便宜一点，因为术后能获得严格体检的捐赠人们似乎要比那些拥有两只肾的人还要寿命更长一些。
