You have absolutely no clue as how to intense, tiring, and stressful it is sitting a court for 4.5 hours per day. In addition, for every hour in court, there is at least one hour of preparation time for lawyers and reading/writing times for judges.. 

You try keeping razor sharp focus for 4 hours, while listening to critical, oftentimes emotional and difficult testimony. And remember, you have to make notes. And, those notes have to be accurate, because they are the basis for your judgment. And remember your judgement will be scrutinize by lawyers, appellate judges, and members of the public. And if you make a mistake due to a lapse in judgment, the media and public will criticize you to no end.

Oh, and if you're a superior court judge, there is a good chance you're 60+ years old.
