Man, I was riding the other day and toothbonked a rail but shit went wrong and I ate shit. I didn't hit my head and I was wearing my helmet at any rate. All the same I saw those little flashy floaters like neurons dying or something. I've had this real shitty headache and I made a quick correlation to that. The real responsibilities probably lay with being awake right now and subsisting on 6ish hours of sleep the last couple weeks. That, or not drinking coffee Sunday or Monday and having a couple strong ones today.
