It was in the 60's so you would have to do the math and speculate whether that was near the end of his career. I can't do that. However, It is unfair to suggest that because Mr. Parker didn't like what Mitose was doing personally, that he would disparage his martial arts skill. Mr. Parker always made the point that Mitose, from the first time he saw him, was not very impressive, and that he was conversely impressively overwhelmed by Chow's capability, and that is why Mitose was never his teacher. The difference for me is I have no need to make an excuse for what someone might have been, or speculate on what they became. I made a judgement on the man's ability based on what I saw, not what I heard, hypothesized, or rationalized. I didn't know the man, but his ability, agenda, and what he was seemed apparent and is well documented outside of martial arts worshippers. I have no problem that some have an opposing view, because it doesn't affect my lineage, or anything I do. However my education and profession pushes me more toward the objective facts, over speculative subjective rationalizations which can obscure and explain anything you want to embrace.
