American Teenagers Dangerously Sleep Deprived

Hi, everyone
I'm Yudai Nakanishi

The reason I chose this news is this article wrote why teenagers become sleepy during classes. I also often become very, very sleepy during classes. So do you?
According this news, teenagers' biologically rhythm is different from other age people.
So, I think school and university should delay start time of classes , for example as Eric Peterson did so.
if they change start time, we will have more sleep time, and we will become more healthy.I hope that the first class of Ritsumei University start a.m. 10.

What time should we change Ritsumei University started time from 9:00 am to?
Why do you think so?
