I used to work in the culture and entertainment field. Some work days during festivals and tours were long. It wasn’t uncommon for me to work 24h+ straight, but I think the longest uninterrupted work session was during the first iteration of a big music festival, where I ended up doing a 53h (to my recollection) day, then taking a 3h nap, and continuing for another several hours. Dev work is so much easier comparatively in that regard - and the money’s better.
