I'd much rather know about something that's
about to be a problem then find out about it at 9 AM when it
is a problem. I would argue staying on top of my work life throughout the day prevents stressful issues. I'm proactive instead of reactive, and when someone up the chain wants to know what's going on, the chances are, I already know, and it's already partway resolved, and those are very comforting answers to be able to give people.
I have a number of hobbies! I'm writing a home automation system, it runs in my car now as well. I play a fair number of games, am a pretty regular movie theater goer, etc. Don't mistake being reachable for being in a constant state of panic, I actually used to have a job where I'd have to duck out of a movie theater if my phone went off when I was on call, and now it's really not a big deal, I can get to it when I have a few moments.
