This happens to me often, and I'm starting to think that my hands have really poor endurance. I've found my hand hurting around what I conjecture to be 250 words in 30 minutes. That seems to me like way too little writing to cause pain. So is it? Can most people write more without trouble? If so, what's my problem?
And when I say writing, I really mean writing only. Typing is excluded. I have no problems with typing.
