Writing injuries, writing links and mental asylums.
It's not the typing, I feel, but the 'mousing' (or the 'tracking' - since I recently went over to a tablet and after a few days found that didn't work for me either - must be just the way I work) so I'm going to move onto my lap top for the rest of the weekend, and maybe find the old RSI book for some advice and exercises (which worked very well last time).
And in the mean time leave you with some links:
Woowoo Teacup's comprehensive and thought-provoking post on writing and the internet - she's asked for more ideas, and although I couldn't think of any maybe you can...
and Lizzy Sidal's very kind review of my novel 98 Reasons For Being. She's done some very interesting research about the history of the Frankfurt mental asylum having just paid a visit to Frankfurt and it is well worth reading.
