Ещё одно публичное выступление автора:
When the Mahtomedi School District of Minnesota pushed their school start time from 7: 30 to 8: 00 a.m., there was a 60 percent reduction in traffic accidents in drivers sixteen to eighteen years of age.
Teton County in Wyoming enacted an even more dramatic change in school start time, shifting from a 7: 35 a.m. bell to a far more biologically reasonable one of 8: 55 a.m. The result was astonishing— a 70 percent reduction in traffic accidents in sixteen- to eighteen-year-old drivers.
