The phenomena of lethargic early-morning teenagers is one I know only too well. I know I am not alone.
But if Paul Kelley and his team are right why do secondary schools start their working day at 9?
Why not 10?
Why are we getting this so wrong if such an obvious solution (including, as a bonus, to traffic congestion, at least in the morning) is readily available?
Ever heard of working parents? Who start work before 10?
