Re: Broken Clavicle - Advice sort
I broke my left collar bone preAikido and did not think it made a difference until I noticed that I prefered right rolls over left rolls. In response I practiced left rolls over and over. As a teacher, I discovered that front rolls are not the best way to take ukemi in almost any situation and taught my students to take back/side ukemi. If your dojo gives you such freedom, I suggest you use your engineering skills to develop your own ukemi system. (Donovan Waite videos might be a big help).
Another thing, I have not met a serious practitioner who has not at some time had a serious injury that sidelined her, I suggest you figure out how to watch classes enjoyably.
