Mostly in here:
This is my brain, age 20. Is there a story out there somewhere in which a character pays extra to get his own copies of an MRI? That may have had a real world inspiration. I got this because I was having weird twitching convulsion things that eventually just went away on their own. No good diagnosis was ever provided, the best the neurologist came up with was sleep deprivation.
I ran across this while digging out my college ID picture for the previous post. It occurred to me as I looked at it that if I were to post it online, and then at some future point society shifts to using brain geometry as a form of identification, I might be screwed. But the fun of showing off my own brain eventually overpowered my fear that the future might turn out to be a work of science fiction from the 70s.
