Re: Aikido survivors
I have never come across yudansha quitting aikido because of declining skill: at least yudansha who will openly admit to this.
I know some half-dozen yudansha who have stopped aikido altogether and it is obvious from their training up to this point that their skill level has not been declining. I am well aware that you have to adapt the way you train to cope with advancing age, but this is not what I mean. You have to do this with anyway.
The reasons for quitting have invariably been 'political'. They have had serious arguments with their instructors or Dojo-cho, or have serious issues with the way their dojo or organization is being run.
