Long before I thought of doing Asian MA (things Asian in those days usually meant 'associated with a(n unpopular) war', I 'did' the US Navy. The service was, sadly, so desperate to fill the 'empty boots' that they offered an instant promotion to petty officer for anyone extending their enlistment by two years. Had a friend do this, and watched the ceremony as he became a 'Shake 'n Bake' E-4, while I remained a mundane E-3. Funny thing, tho, a few years later when I got out we were both E-5's, but he still had two years to serve for the earlier instant gratification.
I think dan rankings only have meaning to each of us personally. Only we know if we've earned it or not, or what we might have 'earned' in life that's doesn't show up on a belt. I admire your example, Doc. It's good for the arts.
