Later Start times for schools.

I have recently read an article about starting schools later in the morning. I completely agree with the article.
Most high schools start about 7:30 in the morning which is completely ridiculous. I personally wake up about 5:30 am every morning to catch my bus and go to sleep at about 11 pm- 12 am every night, depending on the amount of homework I have. According to the article, teenagers my age are theatrically suppose to have about 9 hours of sleep every night ,but I get only about 5 and half or 6 hours every night.
According to the article sleep  deprivation can lead to alcohol/ drug abuse, social problems and depressions. Personally, my lack of sleep reflects on my grades and attitude at school. Last week, I did not get much sleep because of homework and other activities which lead my whole week to become miserable. For example,i had a couple of tests last week and even though I studied for all of them really hard, I knew I did not do as well I could of done. In addition, the whole week I felt pretty sick which was probably due to my lack of sleep.
If school systems would simply push the start times back only an hour, I feel results would be extremely beneficial. The article talked about two studies done by Center for Applied Reaseach and Educational Improvement  in two different schools districts in Minnesota. In "Minneapolis-area school district—Edina, a suburban district who changed their high school start time from 7:20 to 8:30, and the Minneapolis Public Schools, who changed their start time from 7:15 to 8:40." After CAREI recorded data  on grades and school habits of the students and the data  "showed that there was a significant reduction in school dropout rates, less depression, and students reported earning higher grades."
 I think school systems around the country should follow the example of the these two districts.
