You gotta fight for time to use the restroom even: https://idlewords.com/shepard_pee.htm I mean it makes sense in a way. It's probably more cost effective to have 100 people on the ground spreadsheeting out your entire day to the minute than have 1 astronaut hour spent planning, but it would probably drive me completely insane. Reminds me of that story about the earring that slowly absorbs your mind as you let it make every single decision for you: https://gwern.net/doc/fiction/science-fiction/2012-10-03-yva...
That earring story, as some commenters pointed out, is an alternate version of Greg Egan's short story "learning to be me", now easily found in one of his short story compilations. If you haven't yet read Axiomatic as well as Luminous, I highly recommend both.
