Sometimes, I have published a page saying "I am too stressed and am going to take some time off from publishing about world issues." Then I try to do that, although it's difficult for me to shut up.
I don't really feel like shutting up right now, but maybe what I'll do is impose an unspecified hiatus on my writing at this blog, recognizing that my investment in world events, and the times when I'm writing intelligently and helpfully, can be undermined if I don't take stock of what stress might be doing to my health.
