I know that Shioda smoked a lot and drank the hard stuff.
I was at a seminar/demonstration and was shocked to see the senior instructor (won't mention any names) puffing away outside the building every chance he got. I think it was seeing a cigarette, a dogi and hakama together that looked strange.
During his demonstration he coughed a lot and he kept telling the audience that he was fighting the flu. When I was leaving the parking lot I saw him sneaking out a side door, lighting one up.
I have a question: was Ueshiba's smoking responsible for his visions?
