So now you're just projecting what you think his schedule is? Just because he doesn't want to have events scheduled at all hours of the night doesn't mean he actually goes to bed at 8pm and doesn't wake up until 11am. Any normal person needs time to eat dinner, time to unwind before going to bed. Hell I start unwinding around 7pm but don't go to sleep until almost midnight. Maybe you're just one of their weird people who requires zero sleep but the rest of the planet actually takes time to relax so they can get some decent sleep and be up early again the next day.
