  This Ted talk mentions that teens face chronic sleep deprivation due to public policy.Insufficient sleep will bring many adverse effects on health and even society. If school start later, teenagers will allow to have more sufficient sleep. It will improve health and social problems, and the benefits will be huge. Overall, I agree with the idea of ​​delaying school start times.

  I reported this Ted talk. Most of people think that learning one thing need 10,000 hours, turns out we can learn anything in 20 hours! After finishing this report, I learned a lot about the secrets of learning, I also hope that I can use it in my future study.
