I made it to the 21st day of the year before injuring myself this year – an improvement of 6 days over last year. Today, I managed to dislocate my thumb merely by attempting to put my brake light in its clip before riding home. This was quite pathetic really, since the guy standing beside me unlocking his bike will have been none the wiser to what happened, as I masked the sudden need to throw up while putting it back in its socket quite well. Cycling home was pretty sore, and I bandaged it up upon my return, mainly to prevent myself from accidentally using it.
My thumbs are not, in fairness, the strongest part of my body. I have broken them both and dislocated at least one of them (possibly both, I can’t now recall, but I suspect I have), and they are therefore the most likely to damage from standard activities, such as putting a rear brake light in its clip. Need to take more care when doing such risky procedures in future.
