> There needs to be a time when you are completely undisturbed and disconnected. If you are disturbed by work you will think about work while you answer and maybe even after that. That's not good.

IMO this is not a universal truth - I’m sure some people need that level of disconnection, but I don't find I'm one of them. I generally like my job, and don't find that forcing myself to disconnect does me any particular mental good. But other people report needing that separation, and that's fine! I don't think there needs to be a one-size-fits-all answer here.

I do agree with your bus factor argument though.
