I?ve been a martial arts student for a couple of decades and in that time I?ve known quite a few others who were brilliant technicians and were otherwise formidable individuals, but lacked a fundamental skill set: the ability to fall safely and gracefully. This is a grave omission, because training with the belief that things will always go well and as-planned is delusional. Delusion is not a sound context for any serious endeavor; like design, for instance.
