You hospital workers have insane schedules! All of you! I've heard of resident doctors working 36 hour shifts. How do they even function?

I have a friend who is a nurse and he takes all the worst shifts because they pay the best. He doesn't have a family, so it only impacts him, and he's living a FIRE lifestyle (which he's hella good at). But he lost a ton of weight and was as white as a vampire last time I saw him because he never sees the sun. That's taking it a bit too far IMO. But I'm sure he'll be the one laughing when he retires with a paid off house and no debt in a few years.
