TED reaction

This TED is about sleeping. The presenter says sleeping is important to keep motivation and creating ideas.

Although there is no statistical data to show the importance of sleeping, this presentation gives me an opportunity to think my life -style. It is said that sleeping help memorizing. When I was in high school on senior grade, I had to study a lot to enter good university, but I always slept in around 11 O'clock. However, I've heard many of my friends talked that I studied until 2 or 3 o'clock yesterday, and they complained about not memorizing well. Now, I realized my sufficient sleeping helped my memorizing skills. I have a lot of things have to do recently, and I spare my sleeping time. I'll look over it again and take a enough sleep if I have a large amount of work :)
