24 hours is crazy I've only done 19 hours straight. I've been up more than 24 hours because of it. Sure I have worked hours like I described here over the course of my career. I don't always work these crazy shifts though. If anything it's usually only 1 crazy day at a time not 3 days.
It really is a fun job regardless of who it's for. The preplanning is fun it's like Tetris putting cargo on planes but with formulas though. We call it load planning
