What kind of job is it that someone cannot have 8-9 hours sleep a night?! In what world does a perfectly normal human function require an accommodation?!
(front line medical and emergency workers, law enforcement etc, shift workers… are different. But if you needed a regular schedule, esp for health, you would avoid those professions, right?)
We should ALL be aiming for 7-9 hours a night, every night (per all the world’s sleep scientists).
