This is exactly what I was getting at in paragraph 5 of "The Cure" section ("If you find the idea...").
The problem with stress as the root cause is that after I resolved my RSI pain, I have been through tremendously stressful situations during which I was typing a lot, but these have not triggered any RSI pain. So I think there's something more going on unconsciously, and yes I agree with you it sounds pretty far out.
As for exercise, I should have mentioned in the article that I have always exercised regularly and exercise is a big part of my life, even while I was typing a lot, so in my experience exercise (while having may other benefits) did not help my RSI pain.
