I figured out what gave me the brain tired. I had a ocular migraine today. It's a type of migraine that is triggered by ... well, a couple of different things. Like a lot of migraines, it could be stress, or it could be a bright glare from some reflected light, or it could be high blood pressure. All sorts of things.
( Description of the Brain Fog back here. )Anyway... that's the documentation of this episode. I'm hoping tomorrow will be a lot easier, without a bunch of brain fog. The good news is that these rare migraines are the one and only thing that tends to be wrong with me, besides this getting old thing. But that's kind of a normal thing, y'know. Still, all in all, it's a good life, and I'm incredibly blessed to have all sorts of wonderful folks around me. You all make me want to be a better person.
