Lack of sleep is a huge public health danger that our society refuses to take seriously so far.
I highly recommend the book Why We Sleep by Matthew Walker (2018) [1]. It goes into great detail how driving while tired late at night is no different from driving drunk in terms of resulting fatalities -- yet driving while tired is entirely legal while drunk will lose your license.
It's also terrifyingly eye-opening in the number of hospital fatalities from sleep-deprived doctors, surgeons, residents, and nurses with their extremely long shifts.
This is a conversation America needs to be having. Thankfully there are hard-won limits on how many hours a day drivers and pilots can drive and fly... but it's a vastly larger problem than just those professions.
