Went to run at 11km/h ambitiously just now, and my left knee protested 10 minutes into the run. It remembered all too well its previous injury (visits to the doctor; sleeping with my legs curled up cos I couldn't straighten them) and then it spoke its mind. I decided not to push my luck but still I felt deflated.

Bum knee. Bum day. Still working alone in the office. Sigh.
