Early-40s here who still does all-nighters. How long is recovery time for you? What does it entails -ie what doesn't work as much as it should / takes longer while you recover?
Mid 40s and I'll still do all-nighters on occasion when necessary. Recovering from sleep is no problem, recovering from an angry wife after sleeping well into the afternoon is trickier! ;D
I'm very tired a mildly stupid and my body has no idea at all when it should be asleep for about a week at which point i'm mostly but not entirely better. then again I always had trouble with keeping a regular sleep schedule
I have long since learned how to maintain a healthy sleep schedule when the system is not disturbed by stupid decisions, my techniques just don't work as quickly as they used to. (the most impactful technique is "don't stay up all night, idiot")
