funny how work habits change. in grad school I had infinite energy, would be in lab all night, blasting loud music when nobody was around a decade later I only work at night only to finish stuff that is overdue. protected time: my kids are asleep still blast loud music tho ! (on good headphones)

A decade after this you will work at night to make up for all the doctors appointments (and other new self-care necessities) you had to attend to during the day. (I think I'm about a decade older than you?)
