I don't actually think I have autocorrect on but it's a great excuse and I'm sticking to it!
Sometimes I think I have an autocorrect in my brain, or maybe it's a form of dyslexia. Ever since I received a relatively mild traumatic brain injury (also know as a concussion), ironically not on any of my combat tours, but rather from falling on an icy surface on a ski trip in Switzerland, I've had a form of aphasia. For a while I couldn't articulate some words for several seconds, even though I knew exactly what I wanted to say. I could write the words, though, usually, so it was something to do with speaking, not the formation of text in my brain.
Now, though, what occasionally happens is that I know exactly what I am trying to say, but somewhere between my conceptual thought processes and my fingers, it transforms into a similar word. For example, I'll want to write "think" but what comes out on the page is "thing," despite the k and g keys being 4 apart. In some cases, it comes out as above--suggesting for suggestion, which requires several completely different keystrokes.
