I have a handful of degrees in teaching and history but I couldn't stand the public school system. Spent a decade as a martial arts instructor, fantastic job, kept me very fit and like the Boy Scouts I felt it made a positive impression on the students. All that ended when I got injured pretty severely in my late 20's, then again two years later. I've been working an office job I hate since 2008. Tossing around the idea of opening up a gym one of these days.
