IMHO, its not a crisis only an opportunity.
Its is not what is lacking/missing (implied that it was there or should be there) only that there may be more.
In FMA we often say that the art is complete but not finished.
But, I have been a cross-trainer and perpetual-student my whole life.
Each person gives/shares what they have; some will appreciate it, some will reject it, and most will complete ignore it.
So it goes.
Yes...to practice Aikido on the mat is much easier than to practice it on here. I will keep at it.
