"perishable skills"

Very well put.....sadly enough. You have to be willing to put in the time if you expect it to work. And you have to keep training it to be able to use it to best effect.

That may be exactly why many of the "old masters" only taught a few kata and, relatively speaking, a small list of techinques. They needed to keep the list kinda sparten in order to have the time to train it in a dedicated and diligent fashion.....maybe.
I did battle with ignorance today.......and ignorance won. Huey.
