求翻译：　　老年时，有人采访爱迪生，为什么能成为天才？他说：“天才需要百分之百的灵感再加上百分之九十九的汗水。”如果没有爱迪生，我们就不会有光明。当他去世的那一天，爱迪生叫他的妻子关掉了灯，也表示生命已经结束了。是什么意思？

Old age, it was an interview with Edison, and why to become a genius? He said: "Genius needs 100 percent inspiration plus 99% of sweat." If Edison, we would not be bright. When he died, Edison told his wife to turn off the lights, also said that life has ended.
