How many hours of deep work can a person do?

Guess as many as you can. I, personally, prefer to avoid going past 4 hours of deep work, with a 10-15 minutes to split the work in half and recover

As many as they want. Focus isn’t a bad thing. One needs to balance however with interacting with others, eating health, sleep, and self care as well as meditation and exercise.
