sounds almost like the results you get from some of the voice recognition software when the user, regardless of how much they use it, gets excited. now that can make for some funny reading!
I know how that works though. sometimes when I am typing fast the letters get transposed, I skip words because the brain has already gone about 5 words past the point where the finger's memory is full so it misses an unnecessary word or punctuation and, if he is like me also, and does most of his work on the computer at ridiculous hours of the day then fatigue may also be a very large factor as well.
as for being passionate, surely if we got almost any of us worked up enough over a certain subject and were continually pushing their buttons their typing would suffer too, for the Col, it turns out to be a combination of the words warbirds and US and navy ( words seperated to prevent unnecessary excitment for the Col.

)
If only we could find a few elected officals with the same level of zeal and enthusiam in our respective govt's to get behind the warbird movement then we'd see some truly amazing events regarding salvage, recovery, restoration and flying of warbirds. I'd even settle for 1 of those in a sufficiently high place of power in the US, as long as he left the aussie warbirds alone and here.
