CityLab: "That research, which recently led both the CDC and the American Academy of Pediatrics to urge later start times at American schools, shows that teenagers need at least nine hours of sleep a night, and that during puberty the body starts producing the sleep-inducing hormone melatonin at 11 p.m.—a full two hours after adult bodies do. And teens keep pumping the stuff out until around 8 a.m.; perhaps not surprisingly, virtually all American teenagers don’t get nine hours of nightly rest."In the US, suburban school students have their own bus system. This expense benefits the sprawl profiteers, builders, developers, oil, cars, DIY stores, and such, but is paid for by tax payers. In addition, to make these buses work, students must give up sleep.
When people tell you that #freetransit is too expensive, these are just some of the egregious costs of #autosprawl that can be listed that would be relieved by ending the autosprawl system.
