Weird

My typing has gone all to pot over the last few days. Normally, I am a quick and reasonably accurate two(plus)-finger typist, and I don't need to stare at the keyboard in order to find the keys (until I think about it, then I do!) But over the last two / three days, I have been making loads of strange typing errors.

I have had a few things on my mind, but not more than at other times when I haven't noticed this. I've been feeling tired today, and a bit snuffly, but again not more than at other times.

It's worrying me a bit, but mostly I just find it strange.
