I suddenly find I am taking a day off writing to vegetate and read random escapism and generally chill, and keep asking myself, "why?"

This isn't healthy.

@cstross didn't you recently have covid? If so, your brain is telling you that you're not fully healthy and you need to rest.
@aegtx No, I last had COVID in October '22. (I had a booster shot at the beginning of this month.)
