all in my head

I have become fairly convinced that my death will have something to do with my head: a brain tumor, an aneurysm, something hitting me on the head, maybe even a violent decapitation.

I know, I know, it's not a positive side of me. Paranoid. I mean, I don't walk around with a bicycle helmet on or anything, but I probably shouldn't be thinking about the kind of thing that happened to this woman when I am driving in my car.
