The bit that really stuck with me from this podcast was how overworked some medical professionals are, especially those in residency. Which ends up contributing to them making mistakes with their patients, including deadly ones. Shift work is already extremely taxing on the human body, on top of the large amounts of stress nurses and doctors are already under; but on top of that, we're working the newbies 80 hours a week!?

According to Matthew Walker, this phenomenon started with one influential guy who thought it was important for the residents to "prove themselves" by working these insane hours, and it's just kind of stuck since then. Scary stuff, and basically no reason for it.
