I guess there are scientists right now trying to do that, and I hope they'll succeed because the world would be a much cleaner place, wouldn't it? I think it will be great if they invent something so that we only have to sleep for one or two hours every day.

我想有科学家正在尝试这样做，我希望他们能成功，这样世界会变得更干净，不是吗？如果他们发明一种东西，让我们每天只睡一两个小时，那就太好了。
