Eventhough they play God.. Doctors are human too! According to the report, Doctors on-training are still exhausted and that that they should have a 5 hour of uninterrupted sleep after a 16- hour shift. Yes… They get tired too even though we saw some hot residents in Grey’s Anatomy that seems so energetic and horny all the time.. The truth is they too have bleary eye and can cause a medical mistake.. Probably that’s why they can come up to any diagnosis that seems unheard of.. it might have been they were sleep deprived and fogged their brains when they made the wrong diagnosis to the poor patients…
