Back in 2000, I took my 3rd Dan in Aikido. The grading consisted of me instructing a 1/2 day course to a range of grades of Aikido, then peforming techniques as requested by the examiner (Vince Thompson)
However, the most daunting aspect was being asked to to produce a paper on “The Effect Of Aikido On The Individual”. I had not done anything like this in years and to be honest, dreaded the thought.
However, as soon as I had done it, I felt I had actually learned a lot about myself in the process.
