High School starts at 11?

I just heard some interesting news: there are some high schools in England that have decided to push their school days back to start at 11 a.m.! They couldn't seem to overcome their students' staying up late and sleeping through class, so they chose to change themselves rather than working on changing their teenagers. At first, I couldn't believe they waited so long to make this change (it's only just barely come to the states now) since that would've been awesome when I was going through it, but then the other ball dropped- while they do start at the wonderful hour of 11, they don't get out until 5! I don't know if I'd rather do that anymore. I love getting out of class early and having the whole afternoon to do stuff! I have very mixed feelings about this....
