Wrong idea number 3: Inventors are always old people. 

错误的想法3：发明家总是老年人。

Don’t believe that you can’t invent something when you are young. Here are two examples of young inventors:

不要相信你年轻的时候就不能发明东西。下面是两个年轻发明家的例子：

Louis Braille went blind when he was a child. When he was 15, he invented a system of reading and writing for blind people that is still used in most countries today. 

路易·布莱叶小时候失明了。15岁时，他发明了一种盲人读写系统，至今仍在大多数国家使用。

As a young man, George Nissen was watching trapeze artists in a circus. He watched how they fell into the safety net and then bounced back up again. This gave him an idea and he invented the trampoline. 

年轻时，乔治·尼森在马戏团里观看空中飞人表演。他看着他们如何掉进安全网里，然后又反弹起来。这让他产生了一个想法，他发明了蹦床。
