Bubbling from the old memory banks is a quote (paraphrased) from M. Saito to the point that when aikido is done properly there is no opportunity for ukemi. That leaves only the injury or the kind heart of the aikidoka to permit ukemi. Seems ukemi is a training tool (which requires nages permission to use) to prevent a trail of wrecked partners as opposed to an actual method or unique element of aikido.
I agree with that - but in that case, isn't it conditioning your body in the wrong way?
