I don't know if this applies, but I wonder if cognitive therapy ever stops. I type at least a half hour each day, just copying an article or anything, to keep my skills sharp in case a transcription opportunity comes along.

the funny thing is sometimes I bang out my old speed of 100 wpm, and sometimes my left hand doesn't work so well, I know it's my left hand fingers giving me trouble and wonder why it comes and goes.

After my last injury I was only able to type 15 wpm and it came slowly back. The brain is crazy and amazing. when I feel fine I can do 100 again. I don't know if this is cognitive therapy.
