ouch, that does suck.. i remembered when i rolled my ankle once, (which is quite easy for me, since i have hyper-mobile joints) and couldn't go for my nightly walk (yeah, i'm kinda trying to get fit, instead of being a fat slob) so it was kind of annoying to be stuck inside a fair bit. the loss of one bit of freedom and all.
also from time-to-time, i have a benign tremor in my hands (i.e, they shake like crazy) so it's well neigh impossible to draw anything..
but right now, what's irritating me, is the severe lack of decent art supplies, i'm particular about what medium i draw on, and right now, even the local K-mart doesn't have those visual arts diaries i use for my sketches and comicing. instead i have to use some crappy sketchbooks with only 20 or so sheets of paper, and pratically no backing on them..
