A slow 15km today, recovering from Friday’s trauma when I dislocated my shoulder when putting a rucksack on(!) 
Took several hours for the doctors to get it back in. Possible root cause is epileptic seizures I had as a teenager, damaging the sockets. (Have had about 5 dislocations now.) Will go back next week to discuss potential surgery in both shoulders to prevent a reoccurrence (6 months recovery per shoulder?).
