the science has been in for a long long time. early school start times negatively effect adolescents. tired people behind the wheel are as dangerous as drunk drivers. tired kids get in to more trouble. doing drugs to relieve stress, having sex to relieve stress, mischief to relieve stress, diagnosable mental illnesses. more drops outs, more failing. but you can see from the comments people are stubborn and locked in their ways. how about neighborhood busing? ya, i know- mixing the age of kids is a no-no. give me a break. hire another adult to ride herd, you'll be able to afford it by running FULL buses instead of half-empty ones. of course, how much more can you generate with 'learning problems, add, adhd, delinquent behavior'? purposeful? perhaps. shameful? definitely. (now why do i have to score over and over and over again the same comments?)
