Bill Gates condom; Bill Gates is putting out a call to inventors, but he's not looking for software, or the latest high-tech gadget. This time he's in search of a better condom. Condoms are recognized and used by an estimated 750 million people across the world and reduce both unwanted pregnancy and the spread of sexually-transmitted infections. However, unlike most other technologies, they haven't changed much in the last half-century. So isn't it about time for something new?

每天世界有7.5亿人口在使安全套。主要用途是避孕和防止性病感染。但过去半个世纪安全套不像其他科技，安然一成不变，所以是时候应该做出改变了。比尔•盖茨呼吁全球发明者参与，但这次不是软件或高科技配件。这是寻求更好的安全套。
