Csar, regarding
The Rambam writes that a “working person” is someone who learns 8 hours a day and works 3. Not works 9am to 5pm.
How do you reconcile the fact that he worked for the Sultan for many hours and then saw patients at his home, exhausted by the end of the day per his letters. This seems like more than 3 hours. He might not have been able to say no to the Sultan or the sick patients waiting for him.
Do you think that in any century a typical person could possibly make a living working for 3 hours a day?
Do you know the source for the Rambam quote?
