Why can't we have.......A longer lunchtime?

Why can't we have a longer lunch time, I think lunch time is way short we don't have enough time to do the stuff we love jurying lunch break, for example when I was playing a really fun game with my friends we had to stop half way though the game because the bell rang the good things about having a longer lunch time is that kids would get much longer time to eat so that they wouldn't be rushing and they would finish in time for the ten minute eating bell and then at the end of the day you wouldn't here parents asking if their children have eaten the lunch or not,then also if we had a longer lunch time then that would mean longer fun active and a more time to think. so I think that lunch time should be put to two hours instead of one hour.Plus it would mean that the teachers would have much more time to do there work , they would have a longer lunch break and they would get more stuff done and wouldn't to do it some other time.
